# One-way Mode | Hedge Mode

{% hint style="info" %}
The one-way mode cannot lock long and short positions, but the hedge mode can!
{% endhint %}

## One-way mode

In the one-way mode, a contract is only allowed to hold a position in one direction. When opening a position in the opposite direction, the existing position will be closed first, and then the new position will be opened.

> For example, in the BTCUSDT contract, if you hold a long position of 1 BTC in the one-way mode, and then open a short position of 2 BTC, your position will become a short position of 1 BTC.

## Hedge Mode

In the hedge position mode, a contract can hold positions in both long and short directions at the same time. Opening a position in the opposite direction will open a position in the opposite direction, but positions in the opposite direction will not lead to risk hedging. When the price moves in one direction, the position in this direction will be liquidated.

> For example, in the BTCUSDT contract, if you hold a long position of 1 BTC in the hedge mode, and then open a short position of 2 BTC, your position will become a long position of 1 BTC + a short position of 2 BTC.
