This will allow the hotkey to "flatten" all or some positions - that is cancel all open orders and zero out the existing positions for one or more symbols.

 

 

You can specify the Account for the command and the Symbol (or symbol list) for which the orders should be canceled. If not specified, the Account and the Symbol are taken from the window on which the hotkey is executed. If the Symbol is set to be AllSymbols, every position will be flattened.

 

The Position parameter allows you to flatten only short or only long positions. Or Both.
