This is a simplified and effective version of the library for walk forward analysis of trading experts. It collects data about the expert's trade during the optimization process in the metaTrader tester and stores them in intermediate files in the "tester/Files" directory. Then these files can be used by the special WalkForwardBuilder script to build a cluster walk forward report and rolling walk forward reports for refining it. The intermediate files should be manually placed to the "MQL4/Files" directory before running the script.

Using this library without the script is meaningless. The script is free.
