Ninjatrader questions

1. Can I "simulate" (rather replaying) trading using historical data? Can I chose periods of time, e.g. last year?

2. When using simulation based on historical data, can I change time frames? Using mt4 simulator I can only use one time frame during simulation.

Thanks

I believe it depends on your broker's feed. I am not sure if how far back the simulated feed in Ninja trader can go back. Better check with the customer service of Ninja. They are not too bad in answering questions.
