Since cover are orders, they are automatically squared off at the end of the trading session. Here’s what happens in different scenarios:

• If your primary is fully but the SL leg is not triggered, our risk management system will convert the SL leg into a market order and exit at the best available price.
  
• If your primary order is partially executed, the unfilled quantity will be canceled, and the SL leg will be squared off only for the executed portion.
  
• If your primary order is not executed at all, both the primary and SL legs will be canceled automatically at the end of the day.
