Out of Memory

please try to use the option to set maximum memory to custom size. If you select "Let program determine maximum memory", then Java decides how much memory will be used. In your case you can use higher amount.

Furthermore you can try to disable memory protection as shown in a screenshot attached. 

"Out of memory error

StrategyQuant detected too big memory consumption (over 85% of memory was used)

and automatically stopped the project.

It is done to prevent program freezing, it should always operate with less than 85% of memory used. The solution is to increase the maximum available memory in Performance settings or use configuration that uses less memory."

Additionally, I think there is a serious memory leak since build 116 (as reported by many other users in other bug reports), I never had an issue in 115 with genetic evolution, but since 116 and now 117, genetic evolution fills up the allocated 28 GB in no time with just a few generations, while the database holds just 26 strategies at that moment. That is with 32 years of history data H1, and not even using intrabar mode but just selected timeframe and no retests or additional markets or whatever. Something is wrong here...

Isn't it enough to have a 5-10 years history?
