Hello, I am looking for something like the Profit Locker from VECTOR VEST. [login to view URL] This is a dynamic stop loss. You set a 7% stop loss and for each 4.5% gain on the stock, the stop loss moves up 1% to continue to protect your profit. Once you get near a 25% profit the stop loss is very tight. This will be for the Think Or Swim program by TD Ameritrade
