Of course there are ways to enter your “buy in” or initial trade far in advance, via GTC, or trade triggers.
But there should also be a way to pre-enter a conditional trade that would be entered if the first one goes through.
I have an order in now to buy 500 BAC @ 7. So, if that trade is filled, I’d like to have a second trade to sell the 500 @ 7.5 entered immediately, conditional to the first one being filled.
Sounds simple enough, and I believe I found a patent on this sort of mechanism on the internet
but as far as I know, at least Ameritrade has no system for doing this.
