Legend supports the full range of order types available on Hyperliquid. For additional details, see Hyperliquid’s order type documentation.

​

Market

Executes immediately at the current market price. Best for getting in or out of a position quickly when speed matters more than exact price. A slippage buffer is automatically applied to protect against price movement between submission and execution.

​

Limit

Executes at the specified limit price or better. The order rests on the order book until it is filled, canceled, or expires based on its time-in-force setting. Limit orders give you precise control over your entry or exit price, but there is no guarantee of execution — the market must reach your price.

​

Stop Market

A market order that activates when the mark price reaches your trigger price. Commonly used as a stop loss to exit a position if the market moves against you.

• For longs, the trigger price is set below the current price
• For shorts, the trigger price is set above the current price

​

Stop Limit

A limit order that activates when the mark price reaches your trigger price. Works like a stop market, but once triggered, places a limit order at your specified price instead of a market order. Gives more price control than a stop market, but the limit order may not fill if the market moves quickly past your price.

​

Take Profit Market

A market order that activates when the mark price reaches your take profit level. Used to automatically close a position and lock in profit at a target price.

• For longs, the trigger price is set above the current price
• For shorts, the trigger price is set below the current price

​

Take Profit Limit

A limit order that activates when the mark price reaches your take profit level. Works like a take profit market, but places a limit order at your specified price once triggered.

​

Scale

Places multiple limit orders distributed across a price range. Useful for building or exiting a position gradually at different price levels instead of placing a single large order. Parameters:

• Number of orders — how many individual limit orders to place
• Min / Max price — the price range for the orders
• Size skew — controls whether orders are equally sized or weighted toward one end of the range (default: equal)

Scale orders support all three time-in-force options.

​

TWAP

Time-Weighted Average Price. Splits a large order into smaller sub-orders executed at regular intervals (every 30 seconds) over a set duration. This reduces market impact by spreading execution over time. Parameters:

• Duration — the total execution window
• Randomize — optionally randomize timing within the execution window

For full TWAP details, see Hyperliquid’s order type documentation.

Order Modifiers

​

Time in Force

Time-in-force (TIF) controls how long an order remains active:

​

Reduce Only

When enabled, the order can only reduce or close an existing position — it will not open a new position or increase an existing one. Useful for ensuring a stop loss or take profit order doesn’t accidentally flip your position.

​

Take Profit / Stop Loss (TP/SL)

You can attach take profit and/or stop loss levels when placing a market or limit order. These create linked trigger orders that automatically close the position at your target profit or maximum loss.

• TP and SL are both optional — you can set one or both
• You can set TP/SL as a fixed price or as a percentage from your entry
• TP/SL can also be managed on existing positions from the positions table

For full details on TP/SL mechanics, see Hyperliquid’s TP/SL documentation.

​

Trailing Stop

Automatically adjusts your stop price as the market moves in your favor. You set a trailing percentage — the stop price follows the market by that percentage distance. If the market reverses by the trailing amount, a market close is triggered.
