    Instruments/Symbols for different datafeeds...

    I'm currently developing an indicator which needs to do a SizeF() on a string to determine height/width etc. The function needs to know what "Instrument" is being used. For instance, I'm using Zen-Fire, and I'm familiar with the "symbols" like ES, ZB, for S&P, and Bonds, but for other datafeeds these symbols may be different. Is there a "master list" somewhere or a C#/NinjaScript function that can grab a list from the "connected datafeed" at runtime? so I may "map" my indicator according to what feed, etc?

    funk101, you can take a look at the instrument class for this - http://www.ninjatrader-support.com/H...mentClass.html

    However, there should be no need to access a datafeed specific symbol for your products in NinjaScript, as the needed datafeed mapping is setup for each connectivity provider in the Instrument Manager.

      Ok, well let me give you an example...

      When I call GetCurrentBid() on ES it returns ie: 858.xx . If I call it on ZB(zenfire bonds), I get:
      123.xxxxx when I really want 123'xxx. In order to get that result, I have to do a conditional like such:

      if (Instrument.MasterInstrument.Name == "ZN" ||
      Instrument.MasterInstrument.Name == "ZB" ||
      Instrument.MasterInstrument.Name == "ZT")
      {
      bid = String.Format("{0}'{1:000}", Math.Truncate(GetCurrentBid()), (GetCurrentBid() - Math.Truncate(GetCurrentBid())) * 320);
      ask = String.Format("{0}'{1:000}", Math.Truncate(GetCurrentAsk()), (GetCurrentAsk() - Math.Truncate(GetCurrentAsk())) * 320);
      }
      else
      {
      bid = GetCurrentBid().ToString(sizeFormat);
      ask = GetCurrentAsk().ToString(sizeFormat);
      }

      Now, what I'm asking is, is there a master list somewhere, or some runtime way of getting the possible symbol values from the "detected" datafeed so I don't have to "hard-code" each potential symbol?
