How to register/update indicators with custom data?

Hi, I'm trying to use


var _rsi = new RelativeStrengthIndex(_CustomSymbol, 20);
var Cons = new IdentityDataConsolidator();
RegisterIndicator(_CustomSym, _rsi, Cons, x => x.Value);


but getting

Runtime Error: Object reference not set to an instance of an object

Maybe I'm missing something, it's on clean algo.

@Tadas, can you share an algortihm? it's hard to debug these things without.

If you don't want to share it here, you can send me the project id and I can take a peek at it.

Take a peek when you get a chance, there was an easy to overlook error in the code.
public class MyAlgorithm : QCAlgorithm
{
public Indicator _myIndicator;
public override void Initialize()
{
// ... init logic goes here

var _myIndicator = // initialize indicator
// the problem with the above line is it defined a new '_myIndicator' variable
// within the function vs using the class level '_myIndicator' variable defined
// above causing a null reference exception when attempting to access it
}
public void OnData(TradeBars data)
{
// this line will ALWAYS throw because we never set 'this._myIndicator'
if (!_myIndicator.IsReady) return false;
}
}
