Guys I am a little confused about ECN fees. So here is what I know. Please let me know if I am right or add more substance to my statement ECN fees are added if you buy a stock at ASK because you have to pay the MM for the shares? However, you can try to get your order filled at bid, but most likely you are on the wrong side of the trade if it does get filled. What is the difference between direct buy and buy at ask?
