TechnicalIndicators<T, D> class
abstract
Customize the technical indicators.
The technical indicator is a mathematical calculation based on historical price, volume or (in the case of futures contracts) open interest information, which is intended to predict the direction of the financial market.
Indicators generally overlay the chart data to show the data flow over a period of time.
Note: This property is applicable only for financial chart series types.
