How to get dollar value of tick

[westofpluto]

How do we compute the dollar value of a tick for whatever instrument we have applied a strategy to? There was a bad answer to this question many years ago here: https://ninjatrader.com/support/foru...849-tick-value

Unfortunately, this doesn't work - it gives a compiler error:
"An object reference is required for the non-static field, method or property NinjaTrader.Cbi.Instrument.MasterInstrument.get"

It looks like to get Instrument, you have to use bars.Instrument inside method OnBarUpdate.

I don't want to do this. I want to set a private const TICK_VALUE_DOLLARS at the top of my strategy class. I want it to use whatever Instrument is associated with the default data series for this strategy. So how do I do this?

Hello westofpluto,

Thanks for your question.

You can't do this. Instrument objects are accessible as early as State.DataLoaded. The script must reach the part of its life where it wires into data in order to properly access the Instrument object.

You can declare a private double and assign it in State.DataLoaded, however.

else if (State == State.DataLoaded)
{
    myDbl = Instrument.MasterInstrument.PointValue * Instrument.MasterInstrument.TickSize;
}
