Hello,
I'm trying to use MA's with my consolidated 15 minutes bar. I'm getting this error:
Runtime Error: System.ArgumentException: This is a forward only indicator: EMA9(EURUSD_min) Input: 2017-01-03 00:01:00Z Previous: 2017-01-03 00:15:00Z
at QuantConnect.Indicators.IndicatorBase`1[T].Update (T input) [0x00081] in <0c58f49c73874265b0875441bb206894>:0
at QuantConnect.Algorithm.QCAlgorithm+<>c__DisplayClass382_0.<RegisterIndicator>b__1 (System.Object sender, QuantConnect.Data.IBaseData consolidated) [0x00026] in <649bb83cee5643f2928a45185f1e6abd>:0
at (wrapper delegate-invoke) <Module>:invoke_void_object_IBaseData (object,QuantConnect.Data.IBaseData)
This is the code:
//Adding my Assets
AddForex("EURUSD", Resolution.Minute);
//Consolidating my 15 minute bar
var signalCheck = new QuoteBarConsolidator(TimeSpan.FromMinutes(15));
signalCheck.DataConsolidated += onsignalCheck;
//Adding my indicators
EMAFast = EMA("EURUSD", 9);
EMASlow = EMA("EURUSD", 90);
//Registering the indicators to work with the custom bar isntead of the standard resolution
RegisterIndicator("EURUSD", EMAFast, signalCheck);
RegisterIndicator("EURUSD", EMASlow, signalCheck);
Am I doing something wrong or this is a bug?

When we use the indicator help methods, the indicator is registered, using RegisterIndicator, under the hood. You are registering the indicator twice and, consequently, updating it twice and causing that runtime error.
Instead of using the helper method, we must rely on the constructor:
EMAFast = new ExponentialMovingAverage(9); EMASlow = new ExponentialMovingAverage(90);Andrestone
Thank you!
