What is a Market Order on Crypto Futures?

A Market Order on Pluang's Crypto Futures buys or sells a contract immediately at the best available price in the order book, without you specifying an exact price yourself — a Long Market Order matches against the best Ask price, and a Short Market Order matches against the best Bid price, both filling the instant you place the order. Market Orders are the fastest way to open or close a position because they don't wait for a specific price level to be reached; instead they take whatever liquidity is currently sitting at the top of the order book. This makes a Market Order the right choice when getting into or out of a position quickly matters more to you than controlling the exact entry or exit price, while a Limit Order is better suited when price precision matters more than speed.

• Long Market Order (Buy): matched with the best Ask price available at the moment you place the order. Example: you open a Long position of 0.001 BTC by Market Order while the market price is 105,000 USDT — your order executes immediately at the best available price, and the contract nominal you receive reflects the price at which it actually filled, which may differ slightly from the 105,000 USDT you saw beforehand.
• Short Market Order (Sell): matched with the best Bid price available at the moment you place the order, using the same immediate-execution logic as a Long Market Order, just against the opposite side of the order book.
• Market Orders prioritize speed of execution over price control — you're guaranteed to fill, but not guaranteed the exact price you saw before placing the order, especially during fast-moving or thin-liquidity conditions.
• Market Orders can be used both to open a new position and to close an existing one manually, separate from any TP/SL you may have attached.

Related questions:

Q: Will my Market Order always fill at the price I see on the chart?
Not exactly — it fills at the best available price in the order book at the moment of execution, which can differ slightly from the last displayed chart price, particularly when the market is moving quickly or liquidity at that price level is thin.

Q: What's the difference between a Market Order and a Limit Order?
A Market Order fills immediately at the best available price with no price guarantee; a Limit Order only fills at your specified price or better, but isn't guaranteed to fill at all if the market never reaches that level.

Q: Can I attach TP/SL to a Market Order when opening a position?
Yes — you can attach Take Profit and Stop Loss when placing a Market Order, or add them afterward to the resulting position; both Simple and Advanced TP/SL are available regardless of which order type you used to open the position.

Q: Is there a size limit on a single Market Order?
Market Order sizing follows the same contract and margin rules as any other Crypto Futures order — the amount you can place depends on your available margin and the position limits in place, not on the order type itself.
