Market order: short/long

We will illustrate how to open a position at market price with a long position. The process is the same for shorts; you just need to click on “Short” on the home screen. When clicking on long, this is the form that you'll see:

Perps - Market - Long

To switch to short, simply click on the short button located to the right of the green “Long” button.

There are two mandatory field there to open a position:

1. Your margin in USDC on Base

2. Your leverage

The minimum margin requirement is 16.5 USDC. As your leverage increases, the required margin will also increase.

Take profit / Stop loss

An optional field appears at the bottom of the form. By clicking “Add,” you can include take-profit and stop-loss orders to your position.

A take-profit or stop-loss order will automatically close your position when the underlying asset reaches a specific price.

When opening a long position, your SL order cannot be set at a price lower than your estimated liquidation price. Similarly, when opening a short position, it cannot be set at a price higher than your estimated liquidation price.

You can always edit your TP/SL after the position is open. You can learn more about it there.
