Trades can be closed automatically for a number of reasons. They can include:
- Stop loss or take profit being triggered causing positions to close automatically
- Margin stop out occurring as the account no longer has enough free equity to maintain the open trades. Trades may be automatically close trades when margin stop out levels have been breached.
- If you are using an Expert Advisor that could have triggered a command to close a trade. Please be familiar with the conditions in which your Expert Advisor operates.
