I think the most unsung reason for retail trader failure is... COMMISSIONS. Let's say you pay $4.50 round trip and you're going to trade on average 10 ES contracts per trade. And on average you make 5 trades a day. So on average 25 trades a week, and 1300 trades a year. Ok, so 1300 trades times $4.50 commission comes to $5850. But you're trading 10 contracts... so that makes it $58,500 a year in commissions! Unless you really know your stuff, the cost of doing business will eventually erode all of your capital. Crunching the numbers for the first time was enough to turn me off the idea of being a frequent day trader. What a handicap to work with! Not trying to say it can't be done... but day trading is hard enough without a hurdle like this to overcome! If I'm a breakeven swing trader I'll end up with a net loss. If I'm a breakeven day trader I'll blow out my account. I'm interested in what retail traders who trade for a living think about this. Am I over-reacting in any way? Anyone who has counter arguments I'd love to hear them.
