do i always have to press the transmit key on the tws to send orders ? cant i just press the buy or sell key?
BUT -- I strongly suggest you not to choose that option, i have seen instances where you can get pending orders, or out of the market fills, etc... What i do is set "BACKSPACE" as my "transmit order" so that would only be one fast hit away to confirm my order, and i can do a last quick scan before putting my order thru.
I've got shift-s and shift-b linked to a straight buy and sell limit at bid/ask, no auto-stop. shift-c is for cancel, and shift-enter is for transmit. shift-up and shift-down change the limit price. ctrl-shift-s and ctrl-shift-b have auto-stops on them. shift-enter for transmit seems really logical and fast to me. But this arrangement in general has been super fast for me...
