# Order Types

> All order types available on Legend

Legend supports the full range of order types available on Hyperliquid. For additional details, see [Hyperliquid's order type documentation](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/order-types).

## 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](#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

<Note>
  TWAP orders have a **\$300 minimum notional** size (compared to \$10 for other order types).
</Note>

## Order Modifiers

### Time in Force

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

| Setting | Name                | Behavior                                                                               |
| ------- | ------------------- | -------------------------------------------------------------------------------------- |
| **GTC** | Good Til Cancel     | Order rests on the book until filled or manually canceled. This is the default.        |
| **IOC** | Immediate or Cancel | Any portion not immediately filled is canceled.                                        |
| **ALO** | Add Liquidity Only  | Post-only order — rejected if it would immediately match. Guarantees maker fee/rebate. |

### 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](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/take-profit-and-stop-loss-orders-tp-sl).

### 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.

<Note>
  Trailing stop and stop loss are mutually exclusive — setting one clears the other.
