MT4 Backtesting – How to use your own FXT files (NOT MT4 generated data) OK, so you may have some tick data in FXT files that you’d like to use for backtesting, but each time you start the test, the files are overwritten. Here’s a quick workaround. Place the FXT files in your tester/history folder, and rename them all with “x” in the front. 代码和说明详见: http://77z3-fx.com/2012/10/03/mt4-b...-fxt-files-without-using-the-downloaded-data/ 我没实际测试，有需要和兴趣的可以去看看。
