Hi, I'm new to IB. When I tried to put a sell order with the best bid price, sometimes the order won't being executed, it just stay there. I understand it's possibly because of the timing, maybe the market has changed after I put the order. But actually the bid price did not change, and my sell order with that price just not being filled. In case it matters, I'm talking about the future trading, with a paper trading account.
Any ideas?
