Small Exchange POP and Environment Locations
Click below for a PDF of the connectivity information.

The Small Exchange maintains Backbone POPs in the following locations:

Order 3 has a time priority over Order 6, meaning Order 3 will match at the price level of 91.00 before Order 6. Similarly, on the sell side, Order 2 has a time priority over Order 5.

A 7th aggressor order enters the CLOB to buy 40 SM75@ 91.10 and the following trades are produced in this order:

1. 15 SM75@91.06. The best offer available is Order 2 at 91.06 which satisfies the limit price of aggressor Order 7. Order is fully filled and removed from the CLOB.
2. 10 SM75@91.06. Order 7 has a remaining quantity of 25 which matches with Order 5, removing this from the CLOB.
3. 10 SM75@91.07. Order 7 now has remaining working quantity of 15.  There are no offer orders at the 91.06 price level, and the next best offer in the CLOB is Order 4 at 91.07, which also satisfies the aggressor limit price of 91.10.  Order 4 is removed from the CLOB.

Order 7 is placed in the CLOB with a remaining working quantity of 5 as there are not any remaining offers in the CLOB that satisfy the limit price.

The Small Exchange’s Matching Engine generates implied orders based on real, direct orders received by market Participants.  The Exchange supports implied orders for single and multi-leg orders and implied orders are only generated when the markets are in an open state.

Implied single orders are generated from real two-leg orders and single contract orders.  For example, an implied bid order for contract A can be generated from direct bid orders from A+B and direct best offer order for B.

Single Implied Order Generation Rules

1. For every contract, implied orders can be generated for each side based on the best priced order of the contract's CLOB and the two-leg contract's CLOB.
2. The effective limit price of a generated implied order is determined using the multi-leg order formula, taking into consideration side and leg ratios.
   Example
   a. Buy A@90.50 and sell A-B@0.30 => generate implied buy B@90.20
   b. Sell B@90.10 and sell A-B@0.30 => generate implied sell A@90.40
   c. Sell B@50.00 and buy A+2B@180.00 => generate implied buy A@80.00
3. An implied order for a contract which is generated from a multi-leg order that has a leg ratio other than 1 is generated but not distributed over market data protocol. 
   Example
   a. Sell A@80.00 and buy A+2B@180.00 => generate implied buy B@50.00 with minimum required fill quantity of 2 as required by the leg ratio in the multi-leg contract.  The minimum fill requirement makes the implied order not useful to be distributed over market data protocol. 
4. The size of the implied order is determined as a possible fill size between a single order and multi-leg order multiplied by the implied contract ratio in the multi-leg ratio. 
   Example
   a. Buy 15 contracts of A and sell 20 contracts of A-B generate implied buy 15 contracts of B.
   b. Sell 15 contracts of A and buy 10 contracts of A+2B generate implied buy 20 contracts of B (as 10*2).
   c. Sell 15 contracts of A and buy 10 contracts of 2A+3B generate implied buy 21 contracts of B (as 7*3). 

Implied multi-leg orders are generated from existing real best bid and best offer of the leg's contracts.  For example, an implied bid order for contract A+B can be generated from best bid orders of contract A and B.

Multi-leg Implied Order Generation Rules

1. For every multi-leg contract, implied orders can be generated for each side based on the best priced orders of the contract's CLOB.
2. The effective limit price of generated implied order is determined using a multi-leg order formula taking into consideration sides and legs ratios.
   Example:
   Buy A@95.50 and sell B@95.70 => generate implied A-B@-0.20
3. Implied orders for listed multi-leg contracts (specifically, calendar and standard ratio intercommodity spreads) are distributed over market data protocol.
4. The size of generated implied order is determined using the minimum of the leg’s order size.
   Example:
   Buy 15 contracts of A and sell 20 contracts of B => generate implied buy 15 contracts of A-B
5. Implied order generation procedure may not start and may not generate any implied multi-leg orders when there is a high volume of real direct orders from Participants.

Implied orders have a lower matching priority than real, direct orders with the same price.   

An implied order will be canceled and becomes ineligible for matching when one (1) or both of the orders used to generate the implied order is removed from an CLOB by being canceled, expired, filled or replaced.  

When an implied match occurs, the aggressor order with the latest timestamp (e.g. the last order received by the Matching Engine across all orders in the match) receives the best fill price.

Example
4 direct orders are placed into the books:
Order #1 - buy 10 SM75-S10Y@0.02
Order #2 - sell 25 SM75-S10Y@0.05
Order #3 - buy 10 SM75@91.00
Order #4 - sell 15 S10Y@90.98

These direct orders create the below list of implied orders:

1. Buy 10 SM75-S10Y@0.02.  This first level implied multi-leg order is created from Order #3 and Order #4.
2. Buy 10 S10Y@90.95.  This first level single implied order is created from Order #2 and Order #3.
3. Sell 15 SM75@91.03.  This first level single implied order is created from Order #2 and Order #4.
4. Buy 10 SM75@90.97.  This second level single implied order is created from Order #1 and the second implied order above, buy 10 S10Y@90.95. 
5. Sell 10 S10Y@91.01.  This second level single implied order is created from Order #1 and the third implied order above, sell 15 SM75@91.03.

Aggressor Order #5 is received: Sell 25 SM75-S10Y@0.01

This order triggers the following actions:

1. Order #1 (buy 10 SM75-S10Y@0.02) and Order #5 (sell 10 SM75-S10Y@0.02) are matched. This causes implied orders buy 10 SM75@90.97 and sell 10 S10Y@91.01 to be canceled.
2. Order #5 (sell 10 SM75-S10Y@0.02), Order #3 (buy 10 SM75@91.00) and Order #4 (sell 15 S10Y@90.98) are matched. Implied order to buy 10 S10Y@90.95 is canceled and implied order sell 15 SM75@91.03 is reduced to 5 contracts: sell 5 SM75@91.03.

Orders remaining in the book:

Mass quoting functionality allows participants to send a set of two-sided tradable quotes for multiple option instruments within a single message. Each tradeable bid/ask quote is treated as a day limit buy/sell order.

This method is used when a contract's market is open.  When there are multiple orders, the inbound aggressor order will always receive the best price. 

Example

There is a resting order to sell @95.00 and an inbound aggressor order enters the market to buy @96.00.  The resulting trade produced for the orders will have a price of 95.00, which is the best price available when the aggressor order is processed.  Any remaining quantity from the aggressor order will be placed in the CLOB using the priority of its price and time.

This pricing method is used when a contract's market state is in pre-open.  The indicative opening price provides market participants with a probable price and quantity at which the market will open. This price is calculated based on all direct limit orders; bid and offers may cross but no matches occur until the contract's market switches to open.  Stop orders are excluded from this calculation and implied orders are not generated during pre-open. The indicative opening price will be generated and disseminated in the market data at the price level with the largest matching quantity of bids and offers.  Since this is based on the current book and order activity, the indicative opening price may change according to activity and, conversely, if there are not any matching orders, an indicative opening price will not be generated.   

The opening price is calculated using an algorithm that considers the total number of matching buy and sell orders:

1. Buys and sells are totaled at each price level.
2. The price level with the largest number of matching orders on the buy and sell side will be the opening price.
3. If there are several price levels with the same matching quantity, the price closest to the previous day’s settlement will be the opening price.
4. If there are not any crossing buy and sell orders the opening price will be the first traded price after the opening.
   
   ExampleExample
   Previous day settlement = 91.05
   The price 90.98 is chosen as the Opening as the price is closer to the previous day settlement of 91.05

When the market transitions to open, the following steps are performed as a single, atomic transaction in the matching engine:

• The opening price is calculated based on all direct limit orders for the contract's CLOB. This is only done if there has not been any published opening price for the contract on that trading day.
• All direct crossing bid and offer orders are matched, and related trades are produced.
• All changes to the market during the opening are distributed over market data for the contract.
• After the initial opening price is calculated and disseminated, any eligible stop orders will become active.
• Implied matching and pricing is enabled for the contract.

Market with protection orders are submitted without a specified limit price and are executed at the best price available in the CLOB when the order is received. Market with protection orders entered on the Small Exchange are given protection prices to prevent market orders from being filled at extreme prices and the market orders are filled within this predefined range. Protection levels are defined by the Exchange and may vary by market. To determine the protection price on bid orders, protection points are added to the current best offer price. Conversely, protection points are subtracted from the current best bid price to determine the protection price on offer orders. If there is no liquidity on the opposite side so a market order can calculate its protection price, the order is rejected.  Market with protection orders can only have a time in force of Day.

Example

The CLOB is as follows:

A limit order has a specified limit price which defines the maximum price for buying or the minimum price for selling.  The system is designed to execute a buy order at or below the specified limit price and a sell order at or above the specified limit price.

Example

The CLOB is as follows:

Stop with protection orders are entered on the market with a specified price to buy or sell when a future trades past the specified price. When the stop price is reached, the stop order becomes a market order and it is given a protection price to prevent the order from being executed at an extreme price.  The triggered order can only be executed within the protection range limit. Triggered stop orders that are working cannot be replaced, only canceled.

Example

When a stop order or stop-limit reaches the Matching Engine it is validated for a specified stop price.  Buy orders must have a stop price greater than the last traded price and sell orders must have a stop price less than the last traded price.  If the order does not meet this criteria, it is rejected. If a contract does not have a last traded price for current trading session, the previous day’s settlement price is used for validation.  Accepted stop and stop-limit orders are placed in a queue and do not enter the CLOB until the stop price is triggered.  

• Buy stop and stop-limit orders are triggered by a trade at a price equal or above the order’s stop price.
• Sell stop and stop-limit orders are triggered by a trade at a price equal or below the order’s stop price.

Orders received with an incompatible order type and instrument will be rejected.

These orders remain eligible for execution during the session in which it is placed.  After the trading session closes, the remaining portion of all unexecuted day orders will expire.  Day orders are supported for market, stop, limit, and stop-limit orders.

GTC orders remain in effect until the order’s contract is expired or until the order is canceled.  At the close of the contract's last trading day, any unexecuted GTC orders will be expired. The GTC time in force qualifier is supported for stop, limit, and stop-limit orders.

IOC orders received by the Matching Engine are immediately filled for at least the specified minimum quantity and any remaining portion of the order that cannot be immediately filled is canceled.  The IOC qualifier is accepted for limit orders only.

FOK orders must be executed in their entirety immediately.  If the total quantity of a FOK order cannot be immediately filled, the entire order is canceled.  The FOK qualifier is accepted for limit orders.

Each product trading on the Small Exchange has two (2) months available for trading: the current month and the following month.  Once the current month's contract expires, the new month begins trading the trading day after expiration.

Spread trading is simultaneously buying one (1) futures contract and selling another.  Small Exchange supports calendar and intercommodity spreads across certain asset classes. The Exchange’s CLOB treats these defined spreads as separate markets and accepts a single price and quantity even though they are constructed of more than one (1) contract.

Each product will have 2 months listed for trading and these will make-up the months for a calendar spread.  The construction of the spread consists of purchasing the shorter month and selling the longer month or vice versa. Each spread will have its own CLOB, but it is possible through implied pricing, the spread can execute against another spread or against orders in the single leg CLOB.

Example

The Small Exchange accepts recognized spreads between different products with the same expiration month, which are defined below within a 1 by 5 ratio and each recognized ratio will have its own CLOB. It is possible the spread can execute against another spread order or against orders in the single leg CLOB. These accepted spread orders will not receive margin relief.

Additionally, any of the following two products can be traded as an intercommodity spread:

• Small 2YR US Treasury Yield (S2Y)
• Small 10YR US Treasury Yield (S10Y)
• Small 30YR US Treasury Yield (S30Y)

Each option instrument traded on the Small Exchange will have two months available for trading: the current month and the following month.  Once the current month’s contract expires, the new option’s month instrument will begin trading the second business day after expiration.

Below are  multi-leg instruments constraints for options. If these are not met, the order will be rejected.

• Max number of legs is 4
• Max leg ratio: 3:1
• All legs must be for the  same product
• Only one leg can be a futures

Price bands are used to prevent erroneously priced orders from entering the market.  The bands validate limit price-based orders, rejecting any buy orders above the upper band and any sell orders below the lower band. These are dynamic based on the reference price.  The reference price is the last traded price. If it is not yet defined for a trading session, the previous day's settlement is used. The reference price will be added to bids and subtracted from offers.

Logic for single instruments:

<Upper Price Band> = <Reference Price> + <Intrument Price Increment> * <Instrument Upper Price Band Offset>

<Lower Price Band> = <Reference Price> - <Intrument Price Increment> * <Instrument Lower Price Band Offset>

Logic for multileg instruments:

<Upper Price Band> is calculated using multi leg formula by taking taking Upper Price Band for all positive ratio legs and Lower Price Band for all negative ratio legs.

<Lower Price Band> is calculated using multi leg formula by taking taking Lower Price Band for all positive ratio legs and Upper Price Band for all negative ratio legs.

Price bands are applied to all time in force qualifiers. In the case of stop-limit orders, the stop and limit prices for sell orders must be less than the reference price and for buy orders the stop and limit prices must be greater than the reference price. Band validation does not prevent bids below the market or offers above the market from being accepted on the Exchange. Price bands are not applied during the pre-open or pre-open no cancel states.

The Exchange adds a protection level to market orders and stop orders after they are triggered.  The purpose of this is to protect these orders from filling at bad prices that are far off from the market price at the time of the order due to price slippage in an illiquid or volatile market. Protection levels are defined by the Exchange and may vary by market. To determine the protection price on bid orders, protection points are added to the current best offer price. Conversely, protection points are subtracted from the current best bid price to determine the protection price on offer orders. If there is no liquidity on the opposite side in order to calculate the protection price, the order is rejected. 

The daily limit is the maximum price range permitted for a contract during a trading session.  The daily limit helps the Small Exchange maintain stable markets by preventing extraordinary market volatility during periods of significant stress.  This pre-order check is performed on all order types with the exception of good till canceled orders. Buy orders priced above the upper daily limit and sell orders priced below the lower daily limit will be rejected, preventing the market from trading above or below this predetermined price. 

The daily limit is based off the previous day’s settlement price.  This limit can be found on each market’s specific Market Page, in the "Contract Specs" section.

The purpose of a intraday limit is to provide the market a momentary pause during times of increased volatility.  This market halt is intended to give participants time to respond to large, unexpected movements in a particular market on the Small Exchange.  The Exchange employs 2 intraday limits that are based on the previous day’s settlement price.  These limits can be found on each market’s specific Market Page, in the "Contract Specs" section. During a triggered intraday limit event, the market state for that product (front and back month) is switched to “paused” for 3 minutes and the following actions take place: 

• For the first minute, trading is paused and only order cancelations are allowed.
• During the second minute, the market is in a pre-open state.
• In the final minute, the market is in a pre-open no cancel state and then reopens. After the market reopens a new opening price is not calculated or published. 

Clearing Members are required to set maximum order quantity limits on each product for their associated trading firms.  This pre-order validation requires the Clearing Member to define the maximum order quantity that will be accepted and any order over this size will be rejected.  Max quantity limits will default to zero and orders will be rejected until this is updated to a positive value for each product. 

Clearing Members are responsible for setting position exposure limits within each market for their associated trading firms. The matching engine validates orders against the position exposure limits and, if the validation fails, the order will be rejected. If the trading firm has no exposure (zero) limit set for a certain market, all orders received from that firm within that market will be rejected.  When a trading firm is added, the limits default to zero and the Clearing Member must set max long and max short exposure limits to enable trading.

Position limits are calculated by netting the long and short fills then adding gross working orders.

Long positions = long working quantity + day long fills - day short fills

Short positions = short working quantity + day short fills - day long fills

The credit exposure limit is the permitted maximum exposure in USD across the trading day and this can be set by a Clearing Member on their trading firms as an additional way to manage risk.  This limit is the overall exposure allowed per firm and is calculated using each product’s initial margin rate, multiplied by the number of filled and working contracts. Trades are netted by each instrument within each trading firm and working orders are added on a gross basis.  If a working order is canceled, that value is returned to the overall exposure amount. Limits can be updated during the trading day and will reset prior to the start of each new trading day. Clearing Members will be notified as they approach specified thresholds (e.g. 50%, 80%, 90%, etc.).  If the credit limit is met or exceeded, the Clearing Member or the Exchange can use the kill switch to reject new trades and/or cancel working orders.

The kill switch can be activated to either block new orders or block new orders and cancel working orders.  Once the kill switch has been activated, it will stay active until it is deactivated. Clearing Member admins will have access to the kill switch for their firm, their associated trading firms, and they will be able to grant other authorized persons access as applicable.  Appropriate personnel within the Small Exchange will have access to all instances of the kill switch. The kill switch, when activated, will cancel and/or block orders during Pre-open, Open and Paused market states. The kill switch will not cancel orders during Pre-open no cancel and Halted market states.

Kill switch functionality is executed on a best-effort basis.

Self-match prevention is an optional risk control for Participants.  This functionality is intended to prevent the matching of orders with common ownership.  Participants choosing to utilize self-match prevention will send their Small Exchange generated self-match ID with all their orders using FIX tag 2362.  Orders received having an unknown self-match ID will be rejected. Two orders having the same token are prevented from matching by canceling one or both of the orders.  The Participant will have the option to cancel the aggressor order, cancel the resting order, or cancel both orders. This strategy will be sent in tag 8000. Self-match prevention will prevent self-matches for implied trades.

Self-match prevention is executed on a best-effort basis.

Cancel on disconnect is an optional setting for each trading session. Participants will set this when they configure their FIX line.  When enabled, the FIX gateway is monitored for disconnections or timeouts at intervals specified by the Participant when they log on to the FIX session.  When an absence of a heartbeat is detected for the Participant specified time, all the working orders for that session will be canceled, regardless of the order’s time in force.  It is the Participant’s responsibility to reenter all orders that have been canceled by cancel on disconnect. If this functionality works correctly, the Participant will receive a cancel confirmation message for the canceled orders once the FIX session is reconnected.  Cancel on disconnect will cancel orders during Pre-open, Open and Paused market states. Cancel on disconnect will not cancel orders during Pre-open no cancel and Halted market states.

When enabled, cancel on disconnect is executed on a best-effort basis.

The Small Exchange implements message throttling to assist with maintaining an orderly market.  This control reduces negative impacts to the Exchange’s marketplace in the case of a malfunctioning trading system, among other things.  The FIX message throttle is a configuration of the Small Exchange’s FIX gateway to limit the number of messages (New, Replace or Cancel Orders) received from FIX sessions within a time period of 1 second. In the case a Participant exceeds any of the FIX session limits, subsequent messages are rejected until the rate falls below the threshold.

FIX throttling services are executed on a best-effort basis.

The fill rate limit is an optional post trade risk control on the trading firm level that is set for futures and options on futures products.  The Clearing Member will set this limit for each of their trading firms.  If the number of contracts filled in a market breaches a specified limit within a specified period of time, all firm working orders will be cancelled. The Clearing Member will specify the max fill contract quantity and a time interval per each instrument product.  The time interval is a multiple of 100 milliseconds and has a max value of 10 seconds.

If the settings are specified after trades have been executed for the firm, the logic counts the gross number of filled contracts (buys and sells) for the sliding time interval. If the number is greater than the specified limit, the logic will mass cancel, unsolicited, all of (DAY and GTC) the product’s working orders for the trading firm, futures and options. Related options and futures multi-leg orders are mass cancelled as well.

When enabled, fill rate limit is executed on a best-effort basis.

All Futures Contracts, Except Small US Crude Oil (SMO)

If a trade occurs in the last sixty (60) seconds of the contract’s trading hours, the daily settlement value for the front month will be calculated using the volume weighted average price (“VWAP”) of such trades, rounded to the nearest tradable tick, or $0.01.  If there are no trades during this time, the Small Exchange will use the following methodology to determine the daily settlement value for such contracts:

Cash Index Value + (Previous Day’s Back-Front Spread / Days Between Front and Back Month Contracts) x Days to Expiration

Small US Crude Oil (SMO) Futures Contract

If a trade occurs in the last sixty (60) seconds of the contract’s trading hours, the daily settlement value for the front month will be calculated using the volume weighted average price (“VWAP”) of such trades, rounded to the nearest tradable tick, or $0.01.  If there are no Trades during this time, the Exchange will use the last traded price for such day and, if that is not available, then the previous day’s Daily Settlement will be used to determine the Daily Settlement for such Contracts.

All monthly futures contracts not the front month are the back month. If a trade occurs in the last sixty (60) seconds of the contract’s trading hours, the daily settlement value will be calculated using the VWAP of such trades rounded to the nearest tradable tick, or $0.01. If there are no trades during this time, the settlement value of such back month contract will be calculated using calendar spreads. In the absence of relevant calendar spread trades during the trading day, the settlement value for such back month contract will be the front month settlement value for such market plus the previous day's front month minus back month spread value.

Futures Contracts Based on an Equity Index

For all futures contracts based on an Exchange equity index, including Small Cannabis (S420), Small Cryptocurrency (SCCX), Small Stocks 75 (SM75), Small Technology 60 (STIX), and Small Equities 400 (SMES). On the day of expiration, the final settlement of the contract is calculated using the closing price for each component of the index, as determined by the rules of the primary market for that component and disseminated by the primary market (the “Official Closing Price”). If the Official Closing Price for an index component is not disseminated or otherwise determined by 15:45:00 CT, the Official Closing Price for such component will be the last sale during regular trading hours on such day of expiration or, if necessary, on the prior trading day(s); in all cases, the sale will be determined by the Exchange’s Index Calculation Agent on a best-effort’s basis and validated by the Exchange. Each component’s Official Closing Price will be multiplied by its weight in the index. These values are then added together for the final settlement of the contract.

Futures Contracts Based on All Other Indices

For all contracts based on all other Exchange indices, including the Small 2YR US Treasury Yield (S2Y), Small 10YR US Treasury Yield (S10Y), Small 30YR US Treasury Yield (S30), Small US Dollar (SFX), and Small Precious Metals (SPRE). On the day of expiration, the final expiration settlement of the contract is determined using the modified average cash value of the respective cash index, starting at 14:58:30 CT to 14:59:59 CT, inclusive.  The value of the cash index will be recorded for each second of this time frame.  In the event the cash index value does not change during the one-second aggregation period, the value for the prior second is carried forward to ensure this is always comprised of 90 values; further, in the event the cash index value changes multiple times during such one-second aggregation period, the last value is used.  The average of these 90 values is the final expiration settlement value for the product.  The calculation of the final expiration settlement value of each contract is performed by the Exchange’s Index Calculation Agent, and validated by the Exchange.

Small US Crude Oil (SMO) Futures Contract

Contracts are cash-settled in U.S. dollars on the second Friday of the month.  On the day of expiration, the Exchange determines the final settlement price of the Contract by using the equivalent front month price of the corresponding United States-referenced blend of several streams of domestic light sweet crude oil Future contract from the trading day prior, as made public by NYMEX (CL) and as published in the national print press.*

*NYMEX is a registered trademark and CL is a ticker symbol of New York Mercantile Exchange, Inc. and/or its affiliates. Reference is made to them here only to describe the source of the final settlement.

Any request by a Member, Related Party or Participant to invoke the Error Trade Policy must be communicated to the Exchange as soon as possible.  If a potential error Trade is not brought to the Exchange’s attention, with a phone call, email or other communication method deemed acceptable by the Exchange, within eight (8) minutes after Trade occurred the Trade will stand except as noted in Part D (iv).

The Exchange has the authority to adjust Trade prices or cancel Trades when necessary to mitigate market disrupting events caused by malfunctions in the electronic trading platform(s) or errors in Orders submitted by Members and Market Participants.

Any Trade price adjustments or Trade cancellations will be transparent to the market and subject to standards that are clear, fair, and publicly available.

All decisions of the Exchange are final.  The Exchange is not liable for any losses resulting from price adjustments or Trade cancelations.

The Exchange may determine to review a Trade based on analysis of market activity or at the request of a Member, Related Party or Participant.  The request must be communicated to the Exchange, as described above, and within eight (8) minutes of the Trade execution.  The Exchange will determine whether or not a Trade will be subject to review.

The Exchange will make a decision if the Trade in question will be subject to review.  The Exchange will first determine if the Trade price is inside the non-reviewable range.  In deciding if the Trade price is in the non-reviewable range, the Exchange will determine the fair value market price at the time the potential error occurred.  In making the determination, the Exchange may consider all relevant factors, including the last Trade price, the underlying index price, a better bid or offer price, a more recent price in a different Contract month and the prices of related contracts trading on the Exchange or other markets.

A. Trade Price in Non-Reviewable Range

If the Exchange determines the Trade price was inside the non-reviewable range, no further action will be taken, and the Trade will stand.

B. Trade Price Outside Non-Reviewable Range

If the Exchange determines that a Trade price is outside the Non-Reviewable Range, the Trade price will be adjusted to a price that equals the fair value market price for that Contract at the time the Trade in review occurred, plus or minus the Non-Reviewable Range.  In the event there are multiple parties, prices and/or Contracts involved in the Trades in question, the Exchange has the authority to cancel, rather than price adjust, these Trades.  The Exchange will alert Participants to the decision.

C. Contingency Orders Triggered by Error Trade

If an error Trade is busted, either by agreement of the parties thereto or by Exchange staff, the Help Desk will also: (a) bust all Trades that were triggered as a result of Contingency Orders being triggered by such Trade; and (b) cancel all bids and offers that were entered into the Trading System as a result of contingency Orders being triggered by such Trade.  The Exchange will notify the Participants responsible for the Trades so that the original Orders can be re-entered into the Trading System.

D. Alternative Resolution by Agreement of Parties

(i) With the approval of the Exchange, parties to a Trade that is price adjusted may instead mutually agree to cancel the Trade.

(ii) With the approval of the Exchange, parties to a Trade that is busted may instead mutually agree to price adjust the Trade to a price consistent with the adjustment provisions above (Price Adjustments and Trade Cancellations section). 

(iii) Subject to paragraphs (i) and (ii) of this section D, parties to a Trade that is cancelled, or price adjusted may mutually agree to a cash adjustment provided that such adjustments are reported to the Exchange and the parties maintain a record of the adjustment.

(iv) An executed Trade may not be reversed via transfer except where such Trade is determined by the Exchange to be outside of the non-reviewable range but not reported timely, subject to agreement of the parties and approval of the Exchange.Any such transfer must occur at the original Trade price and quantity; however, the parties may mutually agree to a cash adjustment.

E. Liability for Losses Resulting from Price Adjustments or Cancelations
