Hi traders, I user QA/4 in version 4.20.2. and I noticed that the caclucation in summary in porfolio overview is wrong. In the attachment the drawndown (5) is 1.42 % but must near 6% and the Return / DD Ratio is with 38.15 also wrong because must be under 10.
Any other trader havethe same issue?

The QA/4 takes the divided result drawndown($) by 10 and caculates from this value (716$) the DD in % which is wrong, because it shows a very low value which is not true. This is the average from the average.
The real value is add the 10 DD(%) from every stratetgy and divided by 10. The result is the real and true average value of DD in % (6.23%) and not the the average from the average.
Do not work that way. Just because a strategy had a drawdown that was 10 % did not mean the portfolio was at drawdown at all. It calculates the max drawdown for the whole portfolio at a point in time and the max combined drawdown is obviously 1.42 %. That’s why you build portfolios in the first place. Profits ads , drawdowns do not.
