QUANTCONNECT COMMUNITY
I've thrown together an example algorithm that shows how to define indicators on any time frame using a consolidator. I also show how you can combine multiple indicators into more complex things like ratios and even indicators of indicators.
Let me know what you guys think!

// in initialize RegisterIndicator(Symbol, myIndicator, myConsolidator, AveragePriceSelector); public static decimal AveragePriceSelector(BaseData data) { var bar = (TradeBar)bar; return (bar.High + bar.Low)/2; }Also, check out the Field.SevenBar which performs an averaging scheme on OHLC data.Nicholas Caffrey

var ema15 = EMA("SPY", 15, Resolution.Minute);The other method involves manually instantiating the class using the constructor. This is not directly tied to any security when you construct it, but instead we can register it to receive data from other indicators or from a consolidator. In the attached project here I'm manually instantiating the indicators because I want to use them on the 15 bars produced by my consolidator object, so I use method 2:var Symbol = "SPY"; var ema = new ExponentialMovingAverage("this is an indicator name", 15); RegisterIndicator(Symbol, ema, TimeSpan.FromMinutes(15));So to answer your question, the "SPY_EMA15" is just the name of the indicator object and can be an arbitrary string. The indicator name is used by the helper Plot functions for the series name, so be sure to make it unique! I like to use names that indicator where the data came from ("SPY") and what I did with it ("EMA15"). Here's a link to the constructor in question. You can also navigate up a level to see all the code for all the indicators.Jonathan Andre
