Astab. Anchored parameter stability in a walk forward test. >=40 is preferred. Also see Rstab
The logic behind this is in a good trading system, the best parameter should be find quickly, and remain stable as possible over numerous Walk Forward runs. Inversely if a parameter in a trading system is not stable, its less likely to be robust or stable.
For example average(close,x). If x was 99 vs 100 Astab would be degraded. Astab-C would not. But if x was 2 vs 3, Astab-C score would be.

Pearsons - This is the Pearson's correlation to a straight line. The x axis is normally the trade number, but can also be date. The perfect correlation score would be 1.
Rstab. Rolling parameter stability in a walk forward test. >=62 is preferred. See also Astab.
Rstab-C. see This is Anchored parameter stability coarse. See Astab-C above.
VIP – Very important
Walk forward efficiency. This is the annualized rates of return for the out-of-sample results divided by the in-sample results.
