Actually its the opposite. If you are going to trade you are going to be wasting a lot of time in front of a computer. It seems like a better approach to actually get paid for that time rather than wasting day after day, year after year waiting for the hot run.
If you do 10 trades a day it only takes you a month to find out if you can trade without any doubt. My bet is that 99% of people here who trade less than 2-4 times a day cannot say with 100% confidence that they can trade.
If I spend 8hrs in front of the screen and take one 4 tick win after 7hrs 55 minutes, is that any worse than taking 20 trades and walking away with 4 ticks, after 8 hrs ?
I'd prefer the latter.
I'd rather concentrate on the higher probability trades and increase my size rather than take more trades.
