>>One problem we find is that different software has variances in formulas- for example- CCI in WOW is not the same as CCI in Metastock. I get an intermediate term indicator with one system in WOW and Richard Estes gets a short term indicator with the same system in metastock. The complexities of group tests are there. Many have group together to work through email or the SI threads on a new approach.<<

I have this question regarding data.

With most stocks having different price, bar, high, low, close, volume, plots how can system testing cover all stocks with only a few stocks tested? Or how can/does this variation enter into the testing?
