Fast backtest is it possible ?

 

hi,

sorry for bad englih, I have one expert advisor, but backtest is very slow, in robot code have my indicator code, (in this way my robot not need indicator for use) but I thin this is not reason for slow backtest ( because I delete my indicator in robot code, so in this way for my robot use need have my indicator in indicator file ) and result is same so slow backtest, I want know possible write some code for fast backtest ? I use for right backtest Every Tick, but if I use Open Pirces Only backtest is slow again, yes Open Prices Only is fast tahan Every Tick, but this for me is not enough,

Reason:
