What should I use to accomodate both backtesting

[atrader]

and real trading?

I have developed a couple of strategies already. Finally, all has problems in either backtesting or real time trading because the lack of knowledge about some details of NT. Now I am going to make a new strategy. Can anybody help me to see what I should use? My requirements and questions are:

1. The ability to backtest in a same or similar result as real time trading;

2. I am going to make the trading code in second bar object under OnBarUpdate with CalculateOnBarClose to true. Is this the best solution? I know that I will lose the tick handling in this way, but second is good enough for me because I know that tick will not allow backtest.

Thanks!

However, no backtest is ever 100% like live trading:

with interbar granularity you mentioned on your 1st link is for setting CalculateOnBarClose to false and build the capability for backtest, right?

If I set the CalculatOnBarClose to true, do I need to use interbar granularity for backtesting? If I do, do I need to make some code for real time trading?

Hello,

1- Yes, I gave this to you so you understand your options with NT.

2 - No, you don't. Remember even though your strategy may calculate on the close of the bar, your results will be different. See the link I posted.
