New article Timeseries in DoEasy library (part 54): Descendant classes of abstract base indicator has been published:

The article considers creation of classes of descendant objects of base abstract indicator. Such objects will provide access to features of creating indicator EAs, collecting and getting data value statistics of various indicators and prices. Also, create indicator object collection from which getting access to properties and data of each indicator created in the program will be possible.

For testing we need the indicator from the previous article without any changes.
Simply save it in a new folder \MQL5\Indicators\TestDoEasy\Part54\ under a new name TestDoEasyPart54.mq5.

Compile the indicator and launch it on the chart.
The following will be displayed in the journal: all parameters of created indicator Accelerator Oscillator in full , and then its short description:
