Help! Metatrader is eating up my harddisk space! Recently I notice my harddisk running low after few round of backtesting. After some investigation I found out where is the un-used data is gather at. Since there are very less article on the www talking about this, I thought I would share it here.
After running few back test, I notice the data is gather around “tester” folder. This is at /tester/history; in my case, it’s in C:\Program Files\MetaTrader 4\tester\history. I not sure what the file is used for, but they appear after back test. So I suppose this is back-test data. Some can be as large as few gb. Deleting them after back test can free up lots of harddisk spaces.
