# Reverse

Unlike [Reverse Position](https://docs.crosstrade.io/webhooks/commands/reverse-position), which equates to a close position + entry of a specific new order, Reverse is a true inversion of an existing position.

The Reverse command accepts only the `account`  and `instrument` fields. If no position exists in the underlying instrument, CrossTrade will take no action. Otherwise, the position is inverted, i.e., if it was previously long 4 contracts, it will become short 4 contracts.

All orders will be submitted as MARKET orders to perform the reversal.

### Example Payload

This command will reverse the current position and result in an identical position in the opposite direction.

```
key=your-secret-key;
command=reverse;
account=sim101;
instrument=ES 06-26;
```
