I'm up to a level where I can make gross profit consistently by scalping couple nasdaq stocks, but my net profit is close to 0, sometime even negative. The net profit = gross profit - (execution fee + clearing fee + sec fee + activity fee + gateway fee). The gateway fee is what kills my net profit the most. Yestoday afternoon, I made 145$ gross profit, but the gateway fee is 111$, plus other fees, my net was -6$. My major problem is that I use market buy or sell all the time because I need to be fast. And the average gross profit I made on a single trade is only around 2 cents per share. I know some people would use bid and ask, instead of having to pay the gateway fee, they get credits back from the ecn. Today I try to bid/ask rather the entry or the exit in my trading, but I totally fail it. Many time the price just run away without filling my entry order. And for exit, it was even more terrible...At the end of the day, not only my net profit is negative, my gross is also negative. I have some questions for those who scalpe active nasdaq stocks successfully. How do you deal with the order fill? and the gateway fee? Any cheaper ecn? I read somewhere that MLX(ISI) charges only 0.0005$ per share for Nasdaq stocks, that's like 6 time cheaper than ARCA, INET, BRUT etc which charge 0.003$ per share. Somehow I don't see MLX(ISI) on the level 2. Please give me some advices. Thank you!
