Quote from OldTrader:
Here's something to ponder: if you got in toward the beginning of a swing, and out around the end of it, what you would find is that you would average 2-3 points per day in the ES. Go back for instance to the move that began in late November from around 1040. Let's say you bought there, and sold near the top in late January for 1140. A successful trade by anyone's measure....100 points. You would have had to sit with this position for 44 trade days. This works out to 2.27 points per day.
Let's say you bought at 1100 on March 25 and sold today at 1140. Another nice trade....40 points. 3.07 points per day for a holding period of 13 trade days.
Now here's the question: Could you make 2-3 points per day trading the ES in and out? If you could, this equals most of the longer term position trades you might have made had you had very good timing and the patience to allow them to make their move.
Trading in and out take more time, and certainly much higher commissions and/or slippage....a factor that you wanted to ignore but is foolish to ignore because they are a major factor.
My personal opinion is that day trading almost always "sounds" better theoretically. But in my opinion the traders that make the most money are the guys who hold positions for a longer period of time.
