In the last few versions of TWS the stop price on the order ticket gets wiped out if you move to other tabs and change something. For example if you open a ticket for just about anything, pick an order type of STP, enter a stop price, then switch to the TIF tab and change from DAY to GTD, then go back to the Basic tab and the stop price is wiped out. I keep thinking they'll fix this, but so far no luck. It's really annoying as I usually enter the stop price, then the TIF, then the FA allocation, and then when I click Accept I get an error that I need to specify a stop price (because the price I entered has been wiped out).
