Not sure, commission with a decent broker is around 2USD per 100 Stocks trade (buy+sell) which with a stock valued 50USD is equivalent to 2 ticks, I normally make at least 10 to 30 ticks in a winning trade so the 2 ticks that I loose for commissions are really not much, same for a loosing trade where (if I follow my plan) I might be stopped or I may get out at 10 to 20 tick, 2 ticks are a nuisance but do not impact my P/L that much. As for Slippage it normally have no impact on my trades as I trade high volume stocks and use Limit orders. So the problem, at least for me, is following my plan, when I do I make money consistently, when I don't I loose them. Commissions is the price I pay to be allowed to trade, nothing more...
Well, the Roulette being random does not allow any winner but the house in the long term. Trading is somehow different since it is not random as price moves between levels for very good reasons. Understanding these reasons together with tight control over looser trades gives all the edge that is needed. It is not easy but that is the whole point (at least that is what I think) since either a trader makes significantly more ticks than he looses (in which case commission and slippage are just a nuisance) or he does not (in which case he would be loosing money even if he did not have to pay commissions and there was no slippage).
