# Limit

> Set the price you are willing to trade at and choose how unfilled orders are handled.

A limit order buys at your limit price or lower, or sells at your limit price or higher. It can fill immediately if that price matches an existing order. Its time-in-force determines what happens to any unfilled amount. Use a limit order when the execution price matters more than being filled immediately.

## Time-in-force (TIF)

Every limit order on Pacifica uses one of the following TIF options.

* **Good-Til-Cancelled (GTC):** The order remains active on the order book until it is either filled or cancelled.
* **Immediate-or-Cancel (IOC):** The order attempts to match immediately at the specified price (or better). Any portion that is not filled immediately is cancelled.
* **Add-Liquidity-Only (ALO):** Also known as **"Post Only"**. The order is added to the order book only if it does not immediately match against an existing order. If it would cross, it is cancelled.
* **Top-of-Book (TOB):** An ALO order that would cross the book is placed at the best possible maker price instead of being cancelled. For a buy, that is the lowest ask minus one tick. For a sell, it is the highest bid plus one tick.
