OOS % & Runs
Percentage of Out of Sample (OOS) bars & Number of Walk-forward runs. Best to leave on defaults.
If nearest is set to 50%, it will genetically optimize 25% above and 25% below the parameters found in the original system. If this exceeds the range allowed internally in GSB, it will shift the range away from GSB's internal indicator limit.

One can Optimize Price Data. To do that choose "True" or use "false" when not to use.
