Hello Sharapova!
Very good post here. You are very correct that with manual trading we can not have such statistics for any strategy. Simply because we can not execute the trades from Monday to Friday without a miss. Or even one trade for 8 hours and hires another 2 to cover the other 16 hours. Imagine what would be 3 people trading for 1 strategy, or maximum 2-3 if they can do it simultaneously. And I know there are people doing that…
Keep in mind that there are very good manual traders but they do not know actually there are Expert Advisors. Because they are so concentrated in their manual trading, no time to look for something new or an easier way to do the trading..
