    testing if source = external data feed

    Is there a way to know (.i.e, a variable to check) if the current data source is the external data feed (vs. the replay, or sim, or real-time choices)?

    BTW, does BarTimer work with external pre-recorded data feeds?

    This is not officially supported, but I suggest you scroll to the DisplayTime() function in the BarTimer indicator to get an idea of how to do it.

    I don't believe there should be any issue with BarTimer on an external data feed.

      No go. Actually, when I first wrote PRV, I copied the DisplayTime() method from BarTimer and named it SessionActive(). I did not understand why it was needed for BarTimer but took the conservative line & used it as a check on PRV calculations.

      Then I got an email from some-one who uses external data who said this check is always false when connected to external data feed. That seems odd, that BarTimer would also not work (this person does not use BarTimer).

      I am also curious as to why you check the SessionActive method when plotting the PRV. The reason I ask is if connected to "External Data Feed" SessionActive is always false. I use the External Data Feed to do replay of data that is not recorded by Ninja Trader and I had comment out the check for session active.
      So now, the question becomes: Is there ANY reason to check for SessionActive ? Why is DisplayTime checked in BarTimer?

      If I should remove the check in PRV please let me know. It would simplify things.

        Unfortunately this is beyond the level of support we can provide. You can play around with it and see how it reacts differently.
