1. Market Hours. The Exchange and the Clearinghouse will be open for trading on all business days excluding holidays specified on the Website. Market hours shall be 8:30 to 14:30 CPT, Monday through Friday.

2. Procedures. With respect to trading on or through the Exchange, the Exchange and the Clearinghouse may adopt, without limitation, procedures relating to Transactions in Contracts and trading on the Exchange, including procedures to:

   1. disseminate the prices of bids and offers and the prices of trades in Contracts;

   2. record and account for Contracts;

   3. perform market surveillance and regulation on matters affecting Contracts;

   4. establish limits on the number and/or size of Orders that may be submitted by a Participant or Authorized User to the Exchange;

   5. establish position limits on the number of Contracts that can be held by a Participant or customer on the Exchange;

   6. establish limits on the number of messages a Participant can send to the Exchange for a Contract in a given time frame;

   7. establish a limit on the maximum daily price fluctuations for any Contracts and provide for any related restriction or suspension of trading in such Contracts; and

   8. require a suspended or expelled Participant, or a Participant with restricted trading rights, to cause Contracts to be executed for such Participant's account to reduce or eliminate such Participant's open positions.

3. Market Suspension and Emergencies. The Exchange and the Clearinghouse reserve the right to adjust Trading Hours and suspend market activities for all or a subset of Contracts in the case of extenuating market circumstances which include, but are not limited to, any occurrence or circumstance which threatens or may threaten such matters as the fair and orderly trading in, or the liquidation of or delivery pursuant to, any Contracts, and which is determined by the Exchange to require immediate action.

   During an Emergency, the Board may implement temporary emergency procedures and rules ("Emergency Rules"), subject to the applicable provisions of the CEA and CFTC Rules. Emergency Rules may require or authorize the Exchange, the Clearinghouse, the Board, any committee of the Board, the Chief Executive Officer or, in his or her absence, any other Officer to take actions necessary or appropriate to respond to the Emergency, including, but not limited to, the following actions:

   1. suspending or curtailing trading or limiting trading to liquidation only (in whole or in part);

   2. extending or shortening the last trading date for Contracts;

   3. providing alternative settlement mechanisms;

   4. ordering the liquidation or transfer of Transactions, the fixing of a Settlement Price, or the reduction of positions;

   5. extending, limiting or changing the Trading Hours;

   6. temporarily modifying or suspending any provision of the Rules;

   7. requiring Participants to meet special Margin requirements;

   8. imposing or modifying trading limits, price limits and/or position limits; and/or

   9. any other action as directed by the CFTC.

   Before any Emergency Rule may be adopted and enforced, a required vote of the Board must approve the enforcement of such Emergency Rule at a duly convened meeting. Directors may attend such a meeting by teleconference. If the Chief Executive Officer, or another authorized Officer, determines that Emergency Rules must be implemented with respect to an Emergency before a meeting of the Board can reasonably be convened, then the Chief Executive Officer or such Officer shall have the authority, without Board action, to implement any Emergency Rules with respect to such Emergency that he or she deems necessary or appropriate to respond to such Emergency. In such circumstances, the Chief Executive Officer or such Officer must convene a meeting as soon as practicable.

   Whenever the Exchange, the Clearinghouse, the Board, any committee of the Board, the Chief Executive Officer or authorized Officer takes actions necessary or appropriate to respond to an Emergency a duly authorized representative of the Exchange or the Clearinghouse, where possible, will post an announcement in a notice to Participants and Clearing Members. When the Board, any committee of the Board, the Chief Executive Officer or other authorized Officer determines that the Emergency has been reduced sufficiently to allow the Exchange and the Clearinghouse to resume normal functioning, any such actions responding to an Emergency will be terminated.

   The Exchange or the Clearinghouse, as applicable, will notify the CFTC prior to implementing, modifying or terminating an Emergency Rule. If such prior notification is not practicable, the Exchange or the Clearinghouse, as applicable, will notify the CFTC at the earliest possible time after implementation, but in no event more than twenty-four hours after implementation.

   Upon taking any action in response to an Emergency, the Exchange or the Clearinghouse, as applicable, will document the decision-making process related to such action. Such documentation will be kept for at least five (5) years following the date on which the Emergency ceases to exist or to affect the Exchange or the Clearinghouse, as applicable, and all such documentation will be provided to the CFTC upon request.

1. Contracts/Expiries. Contract Specifications are set forth on the Website. Contract Specifications are subject to revision or amendment from time to time.

The Exchange will permit trading only in Contracts that are not readily susceptible to manipulation.

2. To offer new products, the Exchange may request that the CFTC approve a new product prior to listing the product for trading. The submission to the CFTC shall be filed electronically in accordance with CFTC Rules 40.3 and include:

   1. a description of the product with the rules that set forth the Contract's terms and conditions,
   2. an explanation and analysis of the product and its compliance with applicable provisions of the CEA, including core principles, and the CFTC Rules thereunder, including documentation relied upon to establish the basis for compliance with the applicable law, or incorporate information contained in such documentation, with appropriate citations to data sources,

If requested by CFTC staff, the Exchange will provide evidence, information or data demonstrating that the Contract meets, initially or on a continuing basis, the requirements of the CEA, or other requirements for designation or registration under the CEA or the CFTC Rules thereunder. The Exchange shall submit the requested information by the open of business on the date that is two business days from the date of request by CFTC staff, or at the conclusion of such extended period agreed to by CFTC staff after timely receipt of a written request from the Exchange.

1. Each Participant must request one or more Trading Account ID as needed to accommodate the nature and volume of the Participant's business.

2. Each Participant and its Authorized Users must have a unique, Exchange-assigned, registered User ID.

3. Each Order entered will track to a User ID that identifies the Authorized User that entered the Order.

4. No Person may use a User ID to place any Order except as permitted by these Rules, nor may any Person knowingly permit or assist the unauthorized use of a User ID. Each Participant and Authorized User shall ensure that no User ID is used by any Person not authorized by these Rules. Each Participant that is not an individual must have in place policies and procedures acceptable to the Exchange to ensure the proper use and protection of User IDs.

5. Each Participant shall ensure the accuracy of the registration information of its Authorized Users at all times.

6. Each Participant shall be solely responsible for controlling and monitoring the use of all User IDs issued to it and its Authorized Users of the Exchange.

   1. any unauthorized disclosure or use of any User ID assigned to it or any of its Authorized Users and of any other reason for deactivating a User ID; and

   2. any unauthorized access to the Exchange by any Authorized User or by any Person using a User ID assigned to such Participant or Authorized User.

8. Each Participant and its Authorized Users shall be bound by any actions taken through the use of a User ID assigned to such Participant or Authorized User (other than any such actions resulting from the fault or negligence of the Exchange), including the submission of Orders and/or execution of Transactions, whether or not such actions were taken or authorized by such Participant or Authorized User, as the case may be.

9. Each Participant must be able to identify all Orders submitted under an Authorized User's respective User ID at all times.

1. Order Requirements. To be valid, an Order must consist of the following information:

   1. Contract: The Order must be submitted for a Contract for which Orders may be placed.

   2. Order ID: Must be present for identification purposes.

   3. Side: Must be either buy or sell.

   4. Quantity: Number of Contracts to be traded. Must be a positive integer greater than zero and less than maximum Order Quantity as defined in Contract Specifications.

2. Order Types. The following types of Orders are allowed on the Exchange.

   1. Limit Order. Allows the buyer to define the maximum purchase Price and the seller to define the minimum sale Price for a Contract. If any portion of the Order can be matched, it will be immediately executed. Buy Limit Orders will only be executed at or below the limit Price. Sell Limit Orders will only be executed at or above the limit Price. If a Limit Order is not immediately executed, it will remain in the book at the limit Price until the Order is either executed, cancelled, or expires at the end of the trading session.

3. Submission. Submission of an Order to the Trading Platform constitutes a representation by the submitting Participant that it is acting as principal in respect of such Order. Orders may be submitted to the Trading Platform via the API.

   The Exchange reserves the right to temporarily or permanently defer processing Orders that may interfere with the proper functioning of the Exchange. For previously submitted Orders, additional validation checks may be run to ensure that the Order contents are still valid and that the submitting Participant has not been suspended.

   The Exchange may not offer all Contracts and Expiries in a particular Contract.

4. Order Modification. Previously submitted Orders can be modified at any time prior to the Order being fully filled.

5. Order Cancellation.

   1. Orders can be cancelled at any time prior to being fully filled. Once an Order has been fully filled, an Order cannot be cancelled.

   2. Orders can be cancelled individually through the API.

6. Order Submission Period. The Exchange will accept Orders in the time period defined in the respective Contract Specification. The Exchange reserves the right to modify this schedule. All submissions, modifications or cancellations will receive acknowledgement after Exchange processing if they have been accepted.

7. Trade Matching. The Trade Matching Engine matches and fills Orders using a central limit order book ("CLOB") and a price-time priority algorithm. In the event of matching Orders with identical prices, Quantity is filled on a first-in-first-out (FIFO) basis.

8. Clearing. All matched trades generated by the Trade Matching Engine after the application of trade risk limits give rise to binding Exchange Transactions between the applicable Participants, which will be automatically submitted to the Clearinghouse for registration and novation, as described in Chapter 8 and 9 of these Rules. Further description of Clearinghouse procedures and rules can be found in the Clearinghouse rulebook. The Exchange reserves the right to cancel erroneous trades submitted to the Clearinghouse in accordance with Rule 508.

9. Trading Information. The Exchange shall make public daily information on settlement prices, volume, open interest, and opening and closing ranges for actively traded contracts on the contract market. Trading information will be published on the Exchange Website at the end of the day.

1. The Exchange shall designate the Contracts in which Block Trades shall be permitted and determine the minimum block size for such transactions. Block sizes will be posted on the Website.

2. The following rules shall govern Block Trades:

   1. A Block Trade must be for a quantity that is at or more than the applicable minimum threshold. Orders may not be aggregated to achieve the minimum transaction size unless expressly permitted under Applicable Law.

   2. Each Participant entering into a Block Trade must be an Eligible Contract Participant, as defined by the CEA, and approved for Block Trading by the Exchange. Each Participant must have a separate and independent bona fide business purpose for entering a Block Trade.

   3. The price at which a Block Trade is executed must be fair and reasonable in light of:

      1. the size of the Block Trade,
      2. the prices and sizes of other transactions in the same contract at the relevant time,
      3. the prices and sizes of transactions in other relevant markets, including the underlying cash market and related futures markets, at the relevant time, and
      4. the circumstances of the markets or the Participants to the Block Trade.

   4. Block Trades shall not affect Orders on the Exchange's regular market.

   5. Parties to a Block Trade must ensure that each Block Trade is submitted without delay upon execution of the trade, in no event later than fifteen (15) minutes after execution via web platform. The submission must include the Contract(s), contract month(s), price, quantity of the Transaction, time of execution, the respective Clearing Member, as well as any other information that the Exchange may require. The Exchange shall promptly publish price and volume information separately from the reports of Exchange transactions.

   6. Participants involved in the execution of Block Trades must maintain electronic records of all such Block Trades, including an electronic timestamp reflecting the date and time each such Order was received as well as an electronic timestamp reflecting the date and time such Order occurred or was cancelled.

3. Trade Entry. Block Trades must be submitted via web platform, where both approved Participants must confirm the Block Trades, specifying the identical Expiry(s) to be traded, the quantity and price, and the buyer and seller.

4. Modification and Cancelation. Block Trades submitted during the Exchange's Trading Hours, and up to fifteen (15) minutes thereafter, are subject to immediate confirmation by the Exchange and may not be modified or cancelled. If erroneous information has been submitted as part of a Block Trade, the Exchange should be notified as soon as the error is detected. If appropriate, the Exchange will facilitate the modification of the trade on a discretionary basis; any trade modification the Exchange agrees to submit to the Clearinghouse will be done during normal Trading Hours.

5. Risk Limit Validation and Clearing. All Block Trades will be subject to the Exchange's risk controls. Upon verification, the Block Trade will be submitted to the Clearinghouse for novation. The Exchange will make available, via a web interface, confirmation that the Block Trade has been accepted.

The Exchange may permit transfer trades to move positions between Trading Accounts for administrative purposes ("Position Transfers") where no change in ownership is involved. Participants and Clearing Members must obtain approval from the Exchange for a Position Transfer; such approval to be granted at the sole discretion of the Exchange. Position Transfers will not contribute to any reported volume, price, or trading range.

1. Trade Cancellation Authority. The Exchange may adjust trade prices or cancel (bust) trades when such action is necessary to mitigate market disrupting events caused by the improper or erroneous use of the Exchange or by system defects or malfunctions. Notwithstanding any other provision of this Rule 508.1, the Exchange may adjust trade prices or cancel any trade if the Exchange determines that allowing the trade to stand as executed may have a material, adverse effect on the integrity of the market. Any decision of the Exchange with respect to an adjustment or cancellation subject to this Rule 508.1 shall be final.

2. Review of Trades. The Exchange may review a trade based on its analysis of market conditions or a request for review by a user of the Exchange. A request for review must be made within five minutes of the execution of the trade. The Exchange shall promptly determine whether the trade will be subject to review, and upon deciding to review a trade, the Exchange will promptly issue an alert to all Participants on the Exchange indicating that the trade is under review. In the case of Contracts determined by the Exchange to be illiquid, the Exchange may initiate a review up to one hour after the execution of the trade, and has the authority, but not the obligation, to review trades reported more than one hour following execution if it determines that the trade price was significantly out of line with fair value. In the course of its review of any trade, the Exchange may, but is not obligated to, inform any of the parties to the trade of the identity and contact information of any other party to the trade.

1. Daily Settlement. The Exchange will provide the Clearinghouse with Settlement Prices once per day. The Daily Settlement price shall be determined at the end of the Daily Settlement Period as defined in Rule 517.

2. Final Settlement. The Exchange will provide the Clearinghouse with the Final Settlement Prices at the end of the Final Settlement Period on the expiration day of the Contract. Final settlement times for futures shall be 10:00 CPT of the trading day on the last Friday of the expiry month. Trading in an option class shall terminate for final settlement at 14:30 CPT six business days prior to trading termination of the underlying futures contract. If this is not both a London and U.S. business day, trading terminates on the prior London or U.S. business day.

   The Exchange reserves the right to adjust Daily and Final Settlement Prices as it deems necessary based on current market conditions or otherwise.

1. Each Clearing Member and Participant that accesses the Exchange electronically is responsible for maintaining or causing to be maintained a front-end audit trail for all electronic Orders, which shall include Order entry, modification, and cancellation (the "Audit Trail") entered into the Bitnomial System by the Participant for which the Clearing Member is identified in the order or quote submission as the Clearing Member for the execution of the order or quote, including all related modifications and cancellations.

2. Such Audit Trail shall include Orders submitted and the times of Order entry and of any Order modification or cancellation. Times that are so captured must not be capable of being modified by the Person entering the Order and must reflect all necessary data fields specified by the Exchange from time to time. For executed Orders, the Audit Trail must record the execution time of the trade along with all award information.

3. Each Clearing Member and Participant shall maintain such Audit Trail information for a minimum of five (5) years and must have the ability to produce Audit Trail data in a standard format upon request of the Exchange. Notwithstanding anything to the contrary herein, each Participant is required to comply with the provisions of Commission Regulation §1.35 as applicable to that Participant.

Each order submitted to the Exchange must include the correct Customer Type Indicator ("CTI") code. The CTI codes are as follows:

• CTI 1: Orders entered, or trades executed, by an individual for their own account, or for an account they control or have a financial interest in, that does not fall under the CTI 2 definition.

• CTI 2: Orders entered, or trades executed, for the proprietary account of a firm which is either a Participant registered with the Exchange, or a Clearing Member.

• CTI 3: Orders entered, or trades executed, for the personal account of an individual Participant.

• CTI 4: Orders entered, or trades executed, for customers which do not fall under CTI 1, CTI 2, or CTI 3 codes. These would include orders entered by, or on behalf of, clients which are not registered as Participants of the Exchange and are not Clearing Members.

1. The Exchange will make information regarding Orders (including prices bid or offered), trades and any other matters it may deem appropriate available to Participants and other Persons at such times and in such manner (whether through the Exchange, financial information services or otherwise) as it may consider necessary or advisable from time to time.

2. Each Participant or other Person receiving any such information referred to in Rule 512.1 above shall not redistribute such information other than to the extent and in the manner as may be expressly permitted by the Exchange in writing from time to time.

1. Each Participant and Clearing Member shall have written disaster recovery and business continuity policies and procedures in place to ensure it is able to perform certain basic operational functions in the event of a significant internal or external interruption to its operations. At a minimum, the following areas must be addressed in the Participant's or Clear Member's policies and procedures:

   1. each Participant and Clearing Member must have procedures in place to allow it to continue to operate during periods of stress or to transfer accounts to another fully operational Participant or Clearing Member with minimal disruption to the Exchange and the Clearinghouse.

   2. each Participant and Clearing Member must perform periodic testing of disaster recovery and business continuity plans, duplication of critical systems at back up sites and periodic back-up of critical information and provide the Exchange or Clearinghouse with information regarding the foregoing upon request; and

   3. each Participant and Clearing Member must maintain and, at the request of the Exchange or the Clearinghouse, provide accurate and complete information for its key personnel. Each Participant and Clearing Member must inform the Exchange or Clearinghouse in a timely manner whenever a change to its key personnel is made.

2. The Exchange or the Clearinghouse may prescribe additional and/or alterative requirements for a Participant's or Clearing Member's compliance with this rule.

The Exchange enforces a Messaging Policy that limits the number of messages a Participant can submit to the API as defined by the Contract Specifications.

The Exchange enforces Self-Match Prevention ("SMP") to protect against self-trading that violates the Exchange's Wash Trade prohibition set out in Rule 402.10. SMP prevents the matching of orders with the same Trading Account ID. The Exchange reserves the right to change behavior of SMP from time to time.

1. The Exchange may list up to twelve consecutive contract months for all non-Perpetual Futures Contracts. Initial options contract listing shall include at least one strike at the previous settlement price of the underlying contract rounded down to the nearest minimum strike interval. Additional strikes may be listed at the discretion of the Exchange on any trading day.

2. The Exchange may list up to two quarter-century Perpetual Futures expiries per product, with the further dated contract listed no sooner than one year prior to the next-to-expire contract expiry.

1. Settlement Times and Definitions

• Daily Settlement Period: Five minutes prior to Trading Close
• Final Settlement Period: Five minutes prior to Trading Termination
• Settlement Period: Daily or Final Settlement Period
• Roll Period: Five trading days prior to contract expiration day
• Front Month Contract After Roll Period: Next contract to expire
• Deferred Month Contracts: All contracts yet to expire excluding the Front Month Contract
• Pricing Contract: Contract used for determining settlement prices

2. Futures Pricing Contract Selection. Unless during the Roll Period, the Front Month Contract is the Pricing Contract for determining settlement prices. During the Roll Period, the next-to-expire Deferred Month Contract is used as the Pricing Contract.

3. Futures Settlement Price Computation

   1. The settlement price of the Pricing Contract is the volume-weighted average price (VWAP) of all the trades during the Settlement Period.

   2. If no trades occur during the Settlement Period, the settlement price is the time-weighted average price (TWAP) of the bid-ask spread midpoint during the Settlement Period.

   3. If a bid-ask spread isn't available during the Settlement Period, earlier market data or a composite spot price is used from spot markets deemed acceptable by Bitnomial.

   4. All settlement prices are rounded to the nearest tick.

4. Options Settlement Price Computation

   1. The settlement price of the Pricing Contract is the volume-weighted average price (VWAP) of all the trades during the Settlement Period.

   2. If no trades occur during the Settlement Period, the settlement price is the time-weighted average price (TWAP) of the bid-ask spread midpoint during the Settlement Period.

   3. If a bid-ask spread isn't available during the Settlement Period, the settlement price is the output of the Black-Scholes model based on that day's settlement price and 30-day volatility of the underlying contract.

   4. All settlement prices are rounded to the nearest tick.

5. Futures Non-Pricing Contract Settlement Prices. The settlement prices for non-Pricing Contracts are inferred from the quoted spread market relationships to the Pricing Contract settlement price, directly or indirectly.

6. Futures Final Settlement. During the Final Settlement Period for physically settled Contracts, the Front Month Contract final settlement price is determined using the non-Pricing Contract settlement price procedure. See Contract specifications for cash settled products.

7. Options Final Settlement. During the Final Settlement Period the Front Month Option Contract will settle based on the underlying Futures Contract.

8. Sole Discretion. The Exchange has sole discretion to determine an alternative settlement price if the stated settlement procedure produces prices which are not representative of the fair value of the contract.

9. Perpetual Futures Contract Daily Settlement Prices. The Perpetual Futures contract settlement price is calculated using the settlement price futures contract implied spot price:

   1. An implied rate is calculated from the settlement prices of the nearest two contract months in the settlement price futures contract listing series in accordance with Rule 517.5.

   2. The implied rate is applied to the settlement price futures contract's pricing contract to imply a spot price in accordance with Rule 517.5.

   3. The settlement price is calculated in accordance with Rule 517.3.

Following the termination of trading, any option that is in the money shall be automatically exercised by the Clearing House, and any such option that is out of the money shall be abandoned by the Clearinghouse. For the avoidance of doubt, no such option that expires in the money may be abandoned, and no such option that expires out of the money may be exercised.
