Hello eSignal,

The link to the external forum thread appears to be directed at NinjaTrader 7, for which I am not aware of a way to check there is historical data before adding an instrument.

However, with NinjaTrader 8 (the version this thread is in), there is a BarsRequest(). This could be used to check to see if there is a bar returned from a time frame. Theoritically this can be run anytime in any state, but be cautious, this method uses a lot of resources.

http://ninjatrader.com/support/helpGuides/nt8/en-us/barsrequest.htm

The data pulled from this cannot be used as an input series or as a data series, but it would provide information for you to make a switch to skip that particular instrument.

Its also not advised to use logic to add series. This can easily cause difficulties when backtesting and optimizing.

Hello esignal,

Yes, you can backtest an instrument list in NinjaTrader.

When selecting the Instrument drop-down, select an instrument list, select 'Select All'

each title of the portfolio I want to have its own strategy

In you link i don't see that

Ex:

i want backtesting together :

Nd100 with Strategy A
S&pFut with Strategy B
Apple with Strategy C

i want backtesting all ..together

is possibile or not?

Hello esignal,

You would need to backtest each strategy individually. However, you can test multiple instruments by backtesting with an instrument list.

Hello esignal,

NinjaTrader does not have the ability to backtest all strategies at the same time.

Hello turbofib

I've submitted a feature request on your behalf for the NinjaTrader Development to consider adding the ability to backtest multiple strategies at the same time.

Once I have a tracking ID for this request I will forward this to you for future reference.

I appreciate your patience.
