Strategy Tester

 
Hi guys and girls,

So I've heard that the strategy tester in MT4 is a little bit wholly inaccurate. Does anyone have any tips on how to make it less so? For instance commands to avoid and what commands to use instead. I've been doing forward testing using multiple accounts and different parameters, but it takes bloody ages. Any suggestions you can give, or if there is already information you can point me towards then I'd be very grateful.
