Stop orders are submitted on the opposite side of the market than normal Limit orders. A buy stop order is submitted at a price higher than the current best bid but does not fill until that price trades. A sell stop order is submitted at a price lower than the current best offer price.

Stops are useful as loss limits as you can use them to close out a position automatically if the market goes against you.

You can check working orders, fills, and positions by tapping on the appropriate icon in the Monitoring Trading Activity
