Hi there, i want to trade a system that relies on limit orders, but the problem is, i need to submit a whole bunch of limit orders, and that's something i can't do in my IB TWS. the reason of course is that the sum dollar value of the orders exceeds my buying power. (i need to place limit orders for about 100 stocks). is there a program that i can use that will trigger a limit order or market order when a price hits a certain point to get around the problem of a whole bunch of limit orders canceling each other out?
