Backtesting with Magnifier 1min VS Data Replay 1 min

Postby SirHC » 13 May 2013

Hi,

How can we be sure that backtesting is using Magnifier ( 1min or sec, or tick) ?

My backtest with bar magnifier (per tick) is giving quickly a result (same as no bar magnifier option) as it did not download tick per tick historical datas.
And same for magnifier with 1 min.

It seems that this option does not systematically download needed datas.

Did someone get this problem ?

Thanks in advance

Chris

In fact, I'm changing my question :

How can we explain a totally different equity curve between normal backtest with bar Magnifier (1 min) (no IOG) and Equity curve with market data replay (minute by minute) ?

This must be the same thing and we have a huge difference ? What can cause this ?

Does any body ever tested that ?
