You completely missing the point. What every potential investor needs to look for is not how trader traded years ago for 1-2-3 years all by himself but how trader can operate withing certain prearranged risk parameters with rules agreed upon. How trader is mentally stable and can produce within those parameters where down side is being rigorously controlled and investor can see it day by day.
People are being recruited this way into trading companies by the way. If trader is disciplined, consistent and can produce what the problem?
If one wants riskless investment he should be looking elsewhere but the way I am offering is actually the best way cause investor can see how trader is following rules and risk control and how he can perform in the now market. Adjust and so forth.
You will never find any trader here who trades for 5 years making 5% a month cause they are all taken and making good living.
If you want to find talent you go for those early birds but within all parameters. The most important part of trading is discipline and mental stability ability to adjust and follow rules and all the limits set before trading starts. If trader can perform within these limits it is a good idea to first allocation with cut off maximum allowed DD after which trading stops and money taken away.
4-6% is a reasonable max DD for day traders or scalpers.
