1 value

• Main value

Range in (-inf; +inf)

1 signal

• Signal 1 appears when main value crosses zero line. When main value crosses zero line upwards, returns full buy signal. When main value crosses zero line downwards, returns full sell signal.

Fields

period1: PeriodType

MA period. Default is 13.

Range in [2; PeriodType::MAX).

period2: PeriodType

Price change period. Default is 1.

Range in [1; PeriodType::MAX).

method: RegularMethods

MA method. Default is EMA.

source: Source

Price source type of values. Default is Close.
