Caveat here: I don't know what I'm doing I'm trying to trade mini corn and mini wheat with IB Seems like liquidity is not there in the ECBOT night action. So I set limit orders for CBOT daytime. I have not paid $55 per month for CBOT market data through IB. I can get the delayed data through Barchart.com. Since I'm setting limit orders to scale in and out of positions I figured realtime data isn't that important. I'm finding that some of my limit orders even daytime CBOT are not executing. Even when the price when beyond my limit. Anyone else have this problem with IB?
