Dear Ninja

Have you considered having the ability to back tests say as BT does through Esignal's tick replay which I find very helpful on testing new system/strategies?

It would seem you just need a way to stream the data into NT, much like the canned data you get in sim101 account. Maybe allowing a user to input their own test data?

Personally, I find back-testing just allows me to prove my point, yet somehow it never pans for me out in real trading.

Dear Cody

Thank you for the interest.

I do agree that paper trading and real life are very much two different things.

But on the other hand when paper trading two significantly different methods there is some guideline to real time as to how diff the results of one to another.

First let me clarify defitions. What you are asking for is replay functionality not back testing. Back testing is running a trading strategy (buy/sell signals) on a range of histrorical market data. What you would like to do is interactively test discretionary traded methods while historical market data is being relplayed. To that end, we already have reply functionality built into NinjaTrader it is just not publicly released yet. This will be released with NinjaTrader V5 due out later this year.

Any plans to get it to read Ensign data (you'd be getting Ensign's ability to access all data providers) AND playback????
