7.0.1000.4 Inconsistent strategy analyzer graph

[nailz420]

After running the attached strategy, cumulative profit graph displays random results when switching between 2 optimizer results. I expect the graph to stay the same for each of the optimizer results when I switch between them. In the attached screenshots (word doc) you can see I switch between the first 2 results and the each time the graph changed. This happend after I restarted NT, but this time the optimizer results changed as well.

WinXP sp3, 32bit, 4gigs of ram, pentium D

optimized strategy parameter from 1 to 10 on 5 min chart with Default 24/5 session, default optimizer.

Hi Tim,

Thank you for the report, detailed steps, and the provided strategy. Was able to see similar here and we're currently looking into.

The reason the optimizer results were different between runs is because the entries are randomly generated, however that still does not explain why the cumulative profit graph changes. Also, I didn't check if other optimizer graphs are affected as well.

I see. Yeah, that explains it. NT doesn't hold all components of the initial run into memory so it recalculates the executions. This produces different results since your entry conditions are random.
