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

ma: M

Main moving average type.

Default is EMA(13).

Period range in [2; PeriodType::MAX).

period2: PeriodType

Price change period. Default is 1.

Range in [1; PeriodType::MAX).

source: Source

Price source type of values. Default is Close.
