New article Timeseries in DoEasy library (part 55): Indicator collection class has been published:

The article continues developing indicator object classes and their collections. For each indicator object create its description and correct collection class for error-free storage and getting indicator objects from the collection list.

Compile the EA and launch it on the chart in the terminal.
After its initializing, “Experts” journal displays library messages about initialization. Among them there are full and short lists of parameters of two created indicators:

Although, the indicator type is one - AMA, but two handles of this indicator are created since parameters of indicators created were different. Therefore, these are two different indicators - each having its handle. Respectively, two indicator objects are created and placed in indicator collection.
