In IB TWS is it possible to mark a stock as do not sell. In a hurry I've occasionally put a sell order in and then realize I've sold the wrong stock. And just today I was putting a buy order in and for some strange reason this window popped up. "Be careful with proceeding, if you click on okay all positions on this page will be sold". I clicked on cancel but looking ahead I'd like to avoid selling a stock in error. I'm running a Friends and Family account and some accounts are IRAs and some are not.
In account management click on configure/portfolio columns, turn on liquidate last. Then right click on the security in account management, expand all the options, select liquidate last.
