This script will export your trades to a csv file.
The attached file is a setup file, simply double click on it to start the install, when prompted for a folder point the install to the root folder of your MT4 installation NOT the experts folder. The video may be outdated, the script name is "MSFX - Trades History CSV"
Watch the video for more info.
I just updated the script so that it does not rely on my site to be up and running ( see screenshot ), I simply hardcoded a simple html/css header in the mql4 script itself.
