It might 'seem' to take longer to make money but in reality it is shorter. The longer your trading time frame, the higher the percentage of winning trades should become. As such, over a period of a year or so, you should show higher returns than if you are trading very short time frames. Apart from that, if you are trading something like the DOW, you are unlikely to average more than 25 points per day (unless you are very good), but if you were trading it on a weekly basis you would probably average in excess of 150 points. Although the difference might seem marginal it does add up. It is also less stressful.
I know from experience with individual shares that the longer the time frame the bigger the returns and the difference is quite substantial.
