Backtesting trading strategy...!

I am looking to backtest my strategy...

I read through threads here for this but could not find anything of use..

I have demat accounts with IIFL, ShareKhan and Reliance....does anyone know if there is a possibility to backtest on any of these platforms...

If not then can someone advise me if there is some platform where I could do these...

As far as I know, we can't back test our strategy in TT.

Try Amibroker...
