I am a FFasttrade user, and I have recently begun noticing that on occasion when I either try to buy or sell at the inside bid/offer, and I click a price nothing happens. I don't get filled, nor is my order placed in line for execution. It's as if the whole transaction never took place. Now, if I click the price a second time. I have always either been filled or placed in line for execution. I'm using a cable modem, so bandwidth shouldn't be the cause. Has this happened to other FFasttrade users?
