how do I save or export to an exell file the history trades of back testing?
One way of achieving this is to write some additional software: every time when a trade is performed it writes/appends the relevant information to a csv file.
Starting point for the reference manual is here: https://www.mql5.com/en/docs/files
Once your backtest has completed you can go to the correct directory and find the csv file with all trade information there. This file can be read with Excel.
