Order Types

Purrps supports all Hyperliquid order types.

All orders execute directly on Hyperliquid's native order engine. Purrps does not modify execution logic, routing, matching, or priority.

Market: Executes immediately at the best available price.

Limit: Executes at your specified price or better.

Stop Market: Triggers a market order when the stop price is reached.

Stop Limit: Triggers a limit order when the stop price is reached.

Take Profit (TP): Triggers an order when a target price is reached.

Stop Loss (SL): Triggers an order when a loss threshold is reached.

Scale: Places multiple limit orders across a defined price range.

TWAP (Time-Weighted Average Price): Splits a large order into smaller suborders executed over time to reduce market impact.

TWAP Mechanics

Orders are split into suborders sent every 30 seconds
Each suborder has a maximum slippage cap of 3%
If early suborders don't fill due to liquidity or spread conditions, later suborders increase in size (up to 3× standard size) to catch up
TWAP suborders won't execute during post-only periods (e.g. network upgrades)

These can be applied to supported order types:

Reduce Only: Ensures the order only reduces an existing position.

Good-Til-Cancelled (GTC): Order remains active until filled or manually cancelled.

Post Only (ALO): Ensures maker-only execution by preventing immediate matches.

Immediate-Or-Cancel (IOC): Executes immediately and cancels any unfilled portion.
