# How to Place a Limit Order

The **Trigger** function allows users to place **on-chain limit orders** directly within the DEX. Instead of executing at the current market price, users can specify a **target rate** and **execution parameters**.

#### **Key Features**

* **Sell Amount**: The quantity of the selected token to sell (e.g., USDT)
* **Buy Amount**: The amount of the counter token expected at the target rate (e.g., APT).
* **Rate**: The limit price (e.g., 1 APT = 3.981161 USDT).
* **Expiry**: Order validity (e.g., Never, 1 day, 1 week).
* **Execution Fee**: Paid only **upon successful execution**; rewarded to the executor.
* **Gas Fee**: Covers network cost, paid to the executor.
* **Platform Fee**: Charged by the DEX, currently free.

Hyperion is an **open protocol** — anyone can execute Trigger orders and earn the Execution and Gas fees. Users only pay these fees when their orders are successfully executed.

Users create a Trigger order by confirming these parameters. Once the market price reaches the set rate, the trade is executed automatically on-chain.
