Market Close feature allows you to close all your open positions at once.
To use the feature, go to “Open Positions” tab under the chart, and click the “Market” button on the right side. Market Close will find the most beneficial order match on the market to close out your position, whether its a long or a short. If you’re closing a long, the feature will seek to find the highest bid price on the ladder. For a short, it will look for the lowest ask price.
Please note that once you click the button, Market Close cannot be undone. It won’t stop until all your positions are closed. If you have a large number of open contracts, this means you risk running into a loss if the liquidity in the order book is insufficient to close out your position above your long entry price or below your short entry price.
