I don’t remember this difference in profit figures (pls see headline subject heading) happening when I was doing optimisations last year and then putting the results into Excel (to find robust ranges of optimised parameters) but it’s just happened again optimising s trailing stop. 

Is there any reason why an optimised report can’t calculate the same way as a detailed report @GraHal @nicolas? Is it just a case of too many permutations to calculate? 

Cheers
