SQX 112 - Retester Monte Carlo results, Ret/DD ratio shows zero for higher confidence levels

Took a strategy (attached) and retested it.



Looking at Ret/DD many of the values are shown as zero, but not clear why?


See attached screenshot and XML config

DD is zero for most of the simulations because there is no loss trade.

Ret/DD is calculated as NetProfit/DD, due this Ret/DD is 0.


Other problem is that you set Number of simulations to 10. Increase it to at least 100.

Vyhýbáte řešení situace, kde při dělení 0 není výsledek 0 !

Pokud používán automatický filtr  na profitfactor < 1.0 , tak v současné době přijdu o strategie, které jsou v daném typu testu jen ziskové. Což je ale úplně špatně.


Mám podobný problém,  reportovaný viz https://roadmap.strategyquant.com/tasks/sq4_3864



You are trying to avoid to solve the situation when divide by 0 is not a result 0!
If the automatic filter for profitfactor< 1.0 is used, I will also eliminate strategies that are only profitable in the given test type. Which is totally wrong.



I have a similar problem reported on https://roadmap.strategyquant.com/tasks/sq4_3864

ok, we modified it. When Drawdown is zero, then Return/DD = 10.


10 is half of the average maximum Ret/DD value, we return this so that it doesn't distort the fitness if t is computed from Ret/DD..
