The following set of Trading Rules governs orders placed via these trading platforms.</p> 1. Trading on Coinbase Pro and Coinbase Prime <p>1.1 Coinbase operates a central limit 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.</p> 1.2 Orders <p>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.</p> <p>1.22 When a Trader places an Order, that quantity of the relevant Asset becomes subject to a Hold.</p> <p>1.23 A Trader can place an Order as either a Limit Order, a Market Order, or a Stop Order.</p> <p>1.24 A Trader may cancel an open Maker Order or Stop Order at any time before it is Filled. No fees are charged for canceled Orders.</p> 1.3 Limit Orders <p>1.31 A Limit Order is an Order to buy or sell a specified quantity of an Asset at a specified price.</p> <p>1.32 A Limit Order will only ever Fill at the specified price or a better price.</p> <p>1.33 A Limit Order with ‘post-only’ selected will only be posted to the Order Book 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.</p> <p>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.</p> <p>1.35 Limit Orders may be placed with one of the following Time in Force Instructions.</p> <ul> <li>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.</li> <li>Immediate or Cancel: the Order will only be posted to the Order Book to the extent that it would be immediately Filled. any remaining quantity is canceled. This results in a Taker Order.</li> <li>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.</li> </ul> 1.4 Market Orders <p>1.41 A Market Order is an Order to buy or sell a specified quantity of an Asset at the best available price of existing Orders on the Order Book.</p> <p>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.</p> <p>1.43 Depending on the volume and prices of Orders on the Order Book at the time 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’.</p> <p>1.44 A valid Market Order will be immediately posted to the Order Book. A Market Order is always a Taker Order.</p> 1.5 Stop Orders <p>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.</p> <p>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.</p> <p>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.</p> <p>1.54 A Stop Order must be placed as a Stop Limit Order which posts a Limit Order when the Stop Price is triggered.</p> <p>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.</p> <p>1.56 Stop Orders may be placed with one of the following Time in Force Instructions.</p> <ul> <li>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.</li> <li>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.</li> </ul> Warnings <p>The Web Interface will display 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).</p> 1.6 Posting of Orders to the Order Book <p>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.</p> <p>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:</p> <ul> <li>It is canceled by the Trader;</li> <li>It expires due to a Time in Force Instruction. or</li> <li>It is completely Filled by one or more Taker Orders placed by another Trader at the same price.</li> </ul> Order Protections <p>1.63 Market Orders and Limit Orders are subject to a 10% protection point. Market and Limit orders will fill at prices up to 10% 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 or Limit Order would fill against orders beyond the protection point, the Order will partially fill up to the 10% price level and the matching engine will cancel all remaining portions of the Order.</p> Order Minimums/Maximums <p>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://pro.coinbase.com/markets.</p> <p>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://pro.coinbase.com/markets.</p> <p>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.</p> <p>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://pro.coinbase.com/market</p> 1.7 Matching Engine and Order Priority <p>1.71 Coinbase Markets matches Taker Orders with Open Maker Orders on each Order Book based on Price-Time Priority.</p> <p>1.72 Price-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. and 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.</p> <p>1.73 All Traders on accessing Coinbase Markets are subject to the same Price-Time Priority.</p> <p>1.74 Subject to Time in Force Instructions, an Order may be matched with a number of corresponding Orders at the same price.</p> <p>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.</p> 1.8 Fills and Settlement <p>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.</p> <p>1.82 Coinbase Markets settles all Filled Orders immediately, by debiting and crediting the relevant balances of Assets in both Traders’ Accounts.</p> <p>1.83 Subject to daily withdrawal limits a Trader may immediately withdraw all Assets in their Account.</p> 1.9 Trading Fees <p>1.91 Coinbase Pro and Coinbase Prime 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.</p> <p>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.</p> <p>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.</p> <p>1.94 Fees may vary between Order Books. The current fee rates can be found at pro.coinbase.com/fees and prime.coinbase.com/fees.</p> <p>1.95 Volume-based fee discounts are available to all traders based on trades over the trailing 30 day period across all order books.</p> 2.
