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.
