I’m struggling to proplery back test as every time I start downloading historical data on metatrader 4 and begin backtest the computer memory gets overloaded. Ive got 2 VPS and upgraded one of them to allow for more memory but i’m still getting the same problem. AS i’m a mac user am i just going to have to bight the bullet and Buy a windows dekstop. If so what specs do you recomend?
