These backtests are based on a 1k investment.
I believe that backtests are not predictors of future behaviours, but they give us a good idea. And being 99.90, they will give us the most accurate idea.
As a side note I also want to offer that I spent hours canvassing the internet for a cost effective and very easy way to do an unlimited number of such backtests and offer to do them for you, or supply you with the tools to do it.
My accounts will ALWAYS show high DD. This is done purposely to maximize our withdrawals every week.
