# Limit order: short/long

There are three mandatory fields when setting up a limit order: 

1. The limit price - the price at which you wish your order to be filled.
2. The margin.
3. The leverage.

{% hint style="info" %}
When shorting, you cannot set a price higher than the current price, and when longing, you cannot set a price lower than the current price.
{% endhint %}

We will illustrate how to open a position at a limit price with a long position. The process is the same for shorts; simply click on “Short” on the home screen. When you click on “Long,” this is the form you’ll see:
