Trading Rules


Coinbase Markets is Coinbase's set of Central Order Books that are accessed by clients through Coinbase Advanced Trade, Coinbase Pro, and Coinbase Exchange trading platforms. The following set of Trading Rules governs Orders placed via these trading platforms.

1. Trading on Coinbase Advanced Trade, Coinbase Pro, and Coinbase Exchange

1.1 Coinbase operates a Central Order Book trading platform, and settles trades in a number of Digital Asset and Fiat Currency Trading Pairs. Each Trader’s Account will list which Order Books are available to the Trader.

1.2 Orders

1.21 To place an Order on an Order Book, a Trader must have an Available Balance of the relevant Asset in their Account which is sufficient to cover the total value of the Order plus any applicable fees. What

1.22 When a Trader places an Order, that quantity of the relevant Asset becomes subject to a Hold.

1.23 A Trader can place an Order in a variety of manners, including a Limit Order, an Iceberg Limit Order, a Market Order, a Stop Order, or an Iceberg Stop Order.

1.24 A Trader may have the ability to cancel an open Maker Order or Stop Order at any time before it is Filled. No fees are charged for successfully canceled Orders.

1.3 Limit Orders

1.31 A Limit Order is an Order to buy or sell a specified quantity of an Asset at a specified price.

1.32 A Limit Order will only Fill at the specified price or a better price.

1.33 A Limit Order with ‘post-only’ selected will be posted to the Order Book only if it would not be posted at the same price as an existing Order on the Order Book. A Limit Order with ‘post-only’ selected will always be a Maker Order. ‘Post only’ orders cannot be placed during an Auction.

1.34 A Limit Order without ‘post-only’ selected will be immediately posted to the Order Book (subject to any Time in Force Instructions) and can result in a Maker Order or a Taker Order, or an Order that is partially a Maker Order and partially a Taker Order.

1.35 Limit Orders may be placed with one of the following Time in Force Instructions, which may vary by platform:

  • Good til canceled: if posted, the Order will remain on the Order Book until canceled by the Trader. This is the default Time in Force Instruction.

  • Good til time: if posted, the Order will remain on the Order Book until a certain time is reached or the Order is canceled by the Trader.

  • Immediate or Cancel: the Order will be posted to the Order Book only to the extent that it would be immediately Filled; any remaining quantity is canceled. This results in a Taker Order.

  • Fill or Kill: the Order will only be posted to the Order Book if it would be immediately and completely Filled. This results in a Taker Order.

1.36 Iceberg Limit Orders

1.36.1 An Iceberg Limit Order is an Order to buy or sell a specified quantity of an Asset at a specified price without revealing the entire size of the Order to the market. This is achieved by splitting the Order into a Trader determined visible portion that is displayed to the market, while the non-displayed portion remains confidential or hidden from the market. The minimum visible portion of the Order will be the base increment of the asset or 10% of the total Order quantity, whichever is larger. Once the visible portion of the Order is filled, the non-displayed hidden portion is decremented, and a new visible portion is placed on the order book, with new time priority, meaning it will be added to the end of the queue at that price level.

1.36.2 An Iceberg Limit Order will only Fill at the specified price or a better price.

1.36.3 An Iceberg Limit Order can result in a Maker Order or a Taker Order, or an Order that is partially a Maker Order and partially a Taker Order.

1.36.4 An Iceberg Limit Order may be placed with one of the following Time in Force Instructions, which may vary by platform:

  • Good til canceled: if posted, the Order will remain on the Order Book until canceled by the Trader. This is the default Time in Force Instruction.

  • Good til time: if posted, the Order will remain on the Order Book until a certain time is reached or the Order is canceled by the Trader.

  • Immediate or Cancel: the Order will be posted to the Order Book only to the extent that it would be immediately Filled; any remaining quantity is canceled. This results in a Taker Order.

  • Fill or Kill: the Order will only be posted to the Order Book if it would be immediately and completely Filled. This results in a Taker Order.

1.4 Market Orders

1.41 A Market Order is an Order to buy or sell a specified quantity of an Asset at the current best available market price of existing Orders on the Order Book.

1.42 There is no guarantee that a Market Order will Fill at the price specified. A Market Order may Fill at a number of different prices, based on the quantity of the Market Order and the quantities of the existing Orders on the Order Book at the time.

1.43 Depending on the volume and prices of Orders on the Order Book when a Market Order is posted, the Market Order may Fill at a price less favorable than the most recent trade price, in some cases significantly so. This is commonly referred to as ‘slippage’.

1.44 A valid Market Order will be immediately posted to the Order Book. A Market Order is always a Taker Order.

1.5 Stop Orders

1.51 A Stop Order is an instruction to post an Order to buy or sell a specified quantity of an Asset but only if and when the last trade price on the Order Book equals or surpasses the Stop Price.

1.52 Once a Stop Order has been placed, it is considered ‘active’ until it executes by posting the relevant Order when the Stop Price is triggered.

1.53 A Stop Order is not posted to the Order Book and is not visible to other Traders, but any resulting Order is posted and visible. All Stop Orders are placed without 'post-only' enabled.

1.54 A Stop Order must be placed as a Stop Limit Order, which posts a Limit Order when the Stop Price is triggered.

1.55 A Stop Limit Order is not guaranteed to Fill. The Web Interface will display a warning each time a Trader attempts to place a Stop Order.

1.56 Stop Orders may be placed with one of the following Time in Force Instructions.

  • Good til canceled: if posted, the Order will remain on the Order Book until canceled by the Trader. This is the default Time in Force Instruction.

  • Good til time: if posted, the Order will remain on the Order Book until a certain time is reached or the Order is canceled by the trader.

1.57 Iceberg Stop Orders will function the same way as a Stop Order, but when the stop price is triggered an Iceberg Limit Order will be posted.

Warnings

The Web Interface will either display the slippage on a transaction, or otherwise provide a warning to Traders who attempt to place an Order which would completely or partially Fill at a price which is more than 2% away from the last trade price (slippage warning).

1.6 Posting of Orders to the Order Book

1.61 (Taker Order) If an Order is posted to the Order Book at the same price as one or more existing Orders, it is a Taker Order which will result in an immediate Fill at that price, to the extent of the total quantity of those existing Orders.

1.62 (Maker Order) To the extent that an Order is posted to the Order Book at a different price to all existing Orders, it is a Maker Order which will remain open at that price on the Order Book until:

  • It is canceled by the Trader;

  • It expires due to a Time in Force Instruction; or

  • It is completely Filled by one or more Taker Orders placed by another Trader at the same price.

Order Protections

1.63.1 Market Orders, Limit Orders, and Iceberg Limit Orders are subject to a price protection point (PPP). Market Orders, Limit Orders, and Iceberg Limit Orders will Fill at prices up to the PPP from the mid-point price between the best bid and best offer on the Order Book at the time the Order was placed. If a Market Order, Limit Order, or Iceberg Limit Order would Fill against Orders beyond the PPP, the Order will partially Fill up to the PPP level and the matching engine will cancel all remaining portions of the Order. 

For a list of PPPs by asset please see https://exchange.coinbase.com/markets.

1.63.2 At the discretion of Coinbase Market Operations, select Order Books may also employ limit order controls to maintain market health. The “high bid limit” (HBL) order control will limit how high a Buy Limit Order or Iceberg Limit Order can be filled based on the last sale price or the current best bid price. If a Limit Order or Iceberg Limit Order would Fill against Orders beyond the HBL, the Order will partially Fill up to the HBL level and the matching engine will cancel all remaining portions of the Order. The HBL will be calculated as either the current best bid price on the order book or the last execution price, plus the HBL percentage.

Order Minimums/Maximums

1.64 Order Minimums: All Market Orders, Limit Orders, and Stop Orders placed on Coinbase Markets are subject to the minimum order size requirements listed at https://exchange.coinbase.com/markets. Iceberg Limit Orders and Iceberg Stop Orders also have a minimum displayed order size. The minimum visible portion of the Order will be the base increment of the asset or 10% of the total Order quantity, whichever is larger.

1.65 Order Maximums: All Market Orders, Limit Orders without 'post-only' selected, and Stop Orders placed on Coinbase Markets are subject to the maximum order sizes listed at https://exchange.coinbase.com/markets.

1.66 'Post-only' Limit Orders do not have a maximum order size. The size can be in any increment of the base currency above the minimum order size requirements.

1.67 Updating Order Parameters: Coinbase Markets will periodically update these Order Minimums, Order Maximums, and total number of Orders allowed per Order Book to reflect the current state of our marketplace and the notional value of the assets. https://exchange.coinbase.com/markets

1.68 Auctions

1.68.1 Coinbase Market Operations may conduct an Auction to initiate trading in an asset pair on Coinbase Markets. In addition, Coinbase Market Operations may also initiate, at its discretion, an Auction on a listed asset pair based on prevailing market conditions and to ensure fair and orderly markets.

1.68.2 Traders can place Limit Orders on the book over a period of time without matching.  Pro and Exchange applications (including API and data feeds) will show an Indicative Price. Using this Indicative Price as an indicator of the eventual open price, Traders can cancel and resubmit orders until the Auction takes place. Upon completion of the Auction, orders crossing the final opening price will be matched and the book will move to Full Trading,Limit Only, or Cancel Only.

1.68.3 For orders matched at an Auction when the market opens, both sides are charged Taker fees. Orders that remain on the Order Book upon completion of Auction are charged Maker fees.

1.68.4 An Iceberg Limit Order cannot be entered during an Auction. Existing Iceberg orders will be canceled if a book is transitioned to Auction mode.

1.7 Matching Engine and Order Priority

1.71 Coinbase Markets matches Taker Orders with Open Maker Orders on each Order Book based on Price-Display-Time Priority.

1.72 Price-Display-Time Priority means that each time a Taker Order is posted: The Taker Order is matched with the earliest in time Maker Order at the best price on the Order Book; and to the extent that the Taker Order is not completely Filled by that Maker Order, it is matched with any subsequent Maker Orders at that price, in the sequence those Maker Orders were posted. If a Maker Order is an Iceberg Limit Order at the price, the Taker Order will match against the displayed amount of the Iceberg Limit Order, then subsequent Maker Orders at that price. If the Taker Order is not completely Filled by all Maker Orders and the displayed interest of Iceberg Limit Orders, it will then match against the non-displayed portion of the earliest in time Iceberg Limit Orders at the price. To the extent that the Taker Order is not completely Filled by one or more Maker Orders described above, it is matched with one or more Maker Orders at the next best price, in the sequence those Maker Orders were posted, and this process is repeated until the Taker Order is completely Filled.

1.73 All Traders on accessing Coinbase Markets are subject to the same Price-Display-Time Priority.

1.74 Subject to Time in Force Instructions, an Order may be matched with a number of corresponding Orders at the same price.

1.75 Taker Orders are matched with the best available existing Maker Orders. This means that a Limit Order placed outside the market (i.e. a Sell Order below the highest existing Buy Order, or a Buy Order above the lowest existing Sell Order) will be Filled by the best available existing Order rather than an existing Order with the same price as the Limit Order.

1.8 Fills and Settlement

1.81 When a Maker Order is matched with a Taker Order, those Orders are Filled. An Order may be matched with and Filled by one or more Orders at the same price.

1.82 Coinbase Markets settles all Filled Orders immediately, by debiting and crediting the relevant balances of Assets in both Traders’ Accounts.

1.83 Subject to daily withdrawal limits a Trader may immediately withdraw all Assets in their Account.

1.9 Trading Fees

1.91 Coinbase Advanced Trade, Coinbase Pro, and Coinbase Exchange charge a Maker fee for each Maker Order and a Taker fee for each Taker Order that is posted to the Order Book. The fee is charged in the Quote Asset and is calculated as a percentage of the Order quantity.

1.92 A fee is charged by debiting the Trader’s Available Balance for the amount of the fee at the time that the Order is posted.

1.93 If an Order is posted to the Order Book partially as a Maker Order and partially as a Taker Order, a Maker fee applies to the portion posted as a Maker Order and a Taker fee applies to the portion posted as a Taker Order.

1.94 Fees may vary between Order Books. The current fee rates can be found at coinbase.com/advanced-feespro.coinbase.com/fees, , and exchange.coinbase.com/fees.

1.95 Volume-based fee discounts are available to all traders based on trades over the trailing 30 day period across all Order Books. Additional fee rebates may be available based on availability of such rebate programs, and Trader meeting eligibility criteria, which may include minimum maker volume, total volume, or similar across specific time horizons.

1.96 Additional Services: Coinbase may, at its sole discretion, make additional services available to Traders. Coinbase reserves the right to modify these services at any time for any reason, in our sole discretion, including, but not limited to the preservation of market integrity, service limit updates related to maximum/minimum size, rate of use, and participation, technical reasons, or if required by law or regulation. Additional Services may be subject to fees as set forth in the fee schedule located at https://exchange.coinbase.com/fees, or as otherwise communicated.

2. Market Integrity

All trades are final.

2.1 All Fills are final and will not be reversed unless:

  • Coinbase is compelled to do so by any applicable law or regulation; or

  • Due to a serious technical error, Orders or Fills do not occur as specified in these Rules - in which case Coinbase will make all reasonable efforts to restore all Traders to the position they would have been in had the error not occurred.

2.12 Coinbase may cancel Open Orders for any reason, in our sole discretion, including, but not limited to, in the following circumstances:

  • Orders placed by Traders who, in our sole discretion, have engaged in abusive use of the platform, for example, Market Manipulation, or using the API in a manner which unreasonably burdens the platform.

  • Orders which under the circumstances involve an error with respect to price, quantity, or other parameters - a ‘clearly erroneous transaction’.

  • If required by any applicable law or regulation, including specifically where Coinbase is required to suspend or terminate a Trader’s Coinbase Advanced Trade, Coinbase Pro Account, Coinbase Exchange Account or Coinbase Account.

  • If required for technical reasons.

2.2 Access to Coinbase Advanced Trade, Coinbase Pro and Coinbase Exchange

2.21 All Traders have equal access to the Coinbase APIs and Web Interfaces. Coinbase does not provide prioritized access to any Trader.

2.22 Coinbase Market Operations has the authority to take any action deemed appropriate to preserve market integrity. Such actions include, but are not limited to, the halting of trading, modifying risk-mitigating parameters, restricting Trader access to Coinbase Advanced Trade, Coinbase Pro or Coinbase Exchange, restricting order types to post-only or limit only, canceling orders resting in the Order Book, updating the criteria for Trader access to Request For Quote, or any other actions deemed to be in the best interest of the Exchange.

2.23 Traders participating as RFQ Liquidity Providers and responding to RFQs must ensure quotes adhere to the following rules to avoid rejections: (a) all required fields must be present in the quote message, and (b) quote response must be received before the expiration time indicated in the RFQ. A RFQ Liquidity Provider's bid and offer response to a RFQ shall be accompanied by the number of Assets at that price the RFQ Liquidity Provider is willing to buy or sell. A RFQ Liquidity Provider that enters a bid (offer) in an Asset must enter an offer (bid). Every RFQ message issued, and every RFQ Liquidity Provider responsive quote, must be for an initial minimum size of at least one (1) Asset. RFQ Liquidity Provider bids and offers are firm for all orders for the number of Assets specified in the bid and offer for the time indicated in the RFQ. Bids and offers are not firm if: (a) a system malfunction or other circumstance impairs Coinbase’s ability to disseminate or update market quotes in a timely and accurate manner; or (b) during the pre-opening phase. Coinbase reserves the right to revoke a Trader's status as a RFQ Liquidity Provider and participation in the RFQ program if the above criteria are not met, if it believes the RFQ Liquidity provider is not participating in good faith, or if it deems it to be in the best interest of the Exchange.

2.3 Interruptions

2.31 If technical reasons prevent or degrade Traders’ ability to place or cancel Orders, or prevent or degrade access to Coinbase APIs or the Web Interfaces or affect the operation of Coinbase Markets Order Books or matching engines, then Coinbase may, in its discretion, take one or more of the following actions in respect of one or more Order Books;

  • Temporarily disable depositing or withdrawing Assets.

2.34 Coinbase will notify Traders of the move to or from Cancel-only Mode via @CoinbaseSupport on Twitter or status.pro.coinbase.com and status.exchange.coinbase.com.

2.4 Self-trade Prevention

2.41 Traders are not able to place an Order which would result in self-execution—i.e., where the same Trader would act as both the maker and taker for the trade.

2.42 If two Orders of the same quantity would result in self-execution, both Orders are canceled.

2.43 If two Orders of different quantities would result in self-execution, the smaller Order is canceled and the larger order is decremented by an amount equivalent to the smaller quantity. The remainder of the larger order remains Open.

2.5 Flash Crashes and Circuit Breakers

Coinbase Prime Trading Rules

Coinbase Prime provides clients with access to trade execution and automated trade routing services, and may provide additional services offered by Connected Trading Venues through the Coinbase Prime Trading Platform. The following Trading Rules govern the receipt, execution and settlement of orders placed via the Trading Platform. Capitalized terms used herein without definition shall have the meaning assigned to them in the Coinbase Prime Broker Agreement.

1. Accepted Order Types

1.1 The Trading Platform shall accept the following types of Orders to purchase or sell specified Digital Assets as specified below, provided that the Trading Platform may also accept other order types as Coinbase may make available from time to time.

1.11 Limit Order: A Limit Order is an Order to buy or sell a specified quantity of a Digital Asset at a specified price and will only Fill at the specified price or a better price. Limit Orders may be placed with Time in Force Instructions, which may include:

  • Good til canceled (GTC): if submitted, the Order will remain open until canceled by the Trader. GTC acts as the default Time in Force Instruction; or

  • Immediate or Cancel: the Order will only be submitted to the extent that it would be immediately Filled; any remaining unfilled quantity is canceled.

  • Fill or Kill: the Order will only be posted to the Coinbase Exchange Order Book if it would be immediately and completely Filled. If the Order would not be filled, the Order will be canceled.

1.12 Market Order: A Market Order is an Order to buy or sell a specified quantity of a Digital Asset at the best available all-in price, or such other pricing methodology as may be agreed with Coinbase from time to time. For the purposes of these Trading Rules, “all-in price” shall mean a price that is reflective of all transactional or other associated fees, costs, interest charges or expenses applicable to executing that Order. Due to changing market conditions, there is no guarantee that a Market Order will Fill at a specified price or that the specified quantity will be fully executed. A Market Order may Fill at a number of different prices. Depending on volume and prices on the Connected Trading Venues at the time a Market Order is submitted, the Market Order may Fill at a price less favorable than the most recently observed trade price, in some cases significantly so. A valid Market Order will be immediately routed from the Trading Platform to the Connected Trading Venues.

1.13 TWAP Orders: The Time Weighted Average Price Order (“TWAP Order”) seeks to complete the Order by splitting it into small pieces that will be independently traded at different time intervals in a linear fashion across Connected Trading Venues using a range of execution strategies. A Trader can specify a TWAP Order’s: i. Buy/Sell direction; ii. Quantity; iii. Limit Price; iv. Start time; and v. Duration.

1.14 VWAP Orders: The Volume Weighted Average Price Order (“VWAP Order”) seeks to complete the Order by splitting it into small pieces that will be independently traded at different time intervals in a non-linear fashion in line with historical volume patterns across Connected Trading Venues using a range of execution strategies.

1.15 Stop Orders: Coinbase Prime may make Stop Orders available to clients.A Stop Order may only be placed as a Stop-Limit Order. A Stop Order is an instruction to post an Order to buy or sell a specified quantity of an Asset but only if and when the last trade price on the Order Book equals or surpasses the Stop Price. The triggering price will be determined solely by trading on Coinbase Exchange, but the resulting limit order may be executed on any applicable Connected Trading Venue.

  • Coinbase Prime will require the triggering price to be a minimum distance from Coinbase best bid (for sell orders) or Coinbase best offer (for buy orders).

  • At time of order placement, the limit price will be subject to a maximum distance from the specified Stop Price.

2. Order Routing

2.1 Coinbase directs Orders to the Connected Trading Venues on an automated basis using Coinbase Prime’s trading algorithms. The trading logic incorporates a variety of factors relating to the Order and the Connected Trading Venues, which may include but will not be limited to:

  • available prices;

  • size of the order;

  • order type;

  • the likelihood of execution;

  • availability of the Connected Trading Venues;

  • Coinbase Prime’s credit with the Connected Trading Venues; and

  • any other considerations relevant to the execution of an order, which considerations will be determined solely by Coinbase Prime.

  • Coinbase Prime carries out regular reviews of the quality of the Connected Trading Venues to evaluate its execution practices.

Clients electing to exclude particular Connected Trading Venues acknowledge that Coinbase Exchange will not be excluded, the trading logic may not necessarily incorporate the above listed factors, including available prices, to the fullest extent compared with Orders not subject to any such exclusion, and Coinbase Prime has no obligation to provide pricing data for any excluded Connected Trading Venue.

2.2 Trading Controls: To help reduce the likelihood of human error, Coinbase Prime has implemented trading controls that apply to Order entry and Order execution.

2.3 A Client may elect to use the services offered by Coinbase Execution Services. Coinbase, acting as agent, would match client orders over-the-counter and as governed by the provisions of the relevant trading agreement. In such a case, the Client’s order may not be executed on a Connected Trading Venue. By electing to use Coinbase Execution Services, the Client understands and accepts that Coinbase Execution Services may, unless otherwise agreed, eliminate any positions on both sides of the market within an Account after the transaction has been executed.

3. Order Requirements

3.1 Available funds: To submit and execute an Order, Client must have sufficient funds or credit in its Trading Balance to cover the total value of the Order plus any applicable fees. After an Order is submitted, the associated funds become subject to hold until the Order is Filled or any part of the remaining Order is canceled.

3.2 Order Minimums: All Orders placed via the Trading Platform may be subject to minimum order size requirements specified by Coinbase.
