Export Indicator Values

[dirkdiggler87]

Hello,
I'm trying to export OHLC data along with a few indicator values to a csv file. I've referenced the streamwriter indicator file here (https://ninjatrader.com/support/foru...xt-file?t=3475) and got it to work with just the OHLC data. But if I add an indicator value such as BuySellPressure.BuyPressure[0] I get 'BuySellPressure() is a method which is not valid in the given context'. I've tried a few different indicator plots all with similar results. This technique for exporting indicator values worked in NT7 but I cant seem to figure it out in NT8. Thanks.

You are using bar array index[x] when you should be using an absolute value for the method BuySellPressure.

E.g Volume is part of the Bars series so uses index array value which is enclosed by square brackets[]. BuySellPressure is a method which is accessed using absolute value in normal brackets ()

"Volume[0] + ";" + BuySellPressure.BuyPressure[0]" *****method not accessed using square bracket index.

Try, BuySellPressure.BuyPressure(CurrentBar)

Welcome to the forums dirkdiggler87!

As a tip, you could use the Strategy Builder to create logic that checks this indicator's plot, and then you can use the View Code button to see the resulting syntax.

public class MyCustomStrategy13 : Strategy
{
   private BuySellPressure BuySellPressure1; // See here

   protected override void OnStateChange()
   {
      if (State == State.SetDefaults)
      {
         ...
      }
      else if (State == State.DataLoaded)
      {
         BuySellPressure1 = BuySellPressure(Close); // See here
      }
   }

   protected override void OnBarUpdate()
   {
      if ([B]BuySellPressure1.BuyPressure[0][/B] == 0) // See here
      {
      }
    }
}

We look forward to assisting.
