2 values

• main value

Range in [0.0; 1.0].

• signal line value

Range in [0.0; 1.0].

3 signals

• Signal #1

When main value crosses lower bound upwards, returns full buy signal. When main value crosses upper bound downwards, returns full sell signal. Otherwise returns no signal.

• Signal #2

When signal line value crosses lower bound upwards, returns full buy signal. When signal line value crosses upper bound downwards, returns full sell signal. Otherwise returns no signal.

• Signal #3

When main value crosses signal line upwards, returns full buy signal. When main value crosses signal line downwards, returns full sell signal. Otherwise returns no signal.

Fields

period: PeriodType

Period for searching highest high and lowest low. Default is 14.

smooth_k: PeriodType

Period for smoothing main value. Default is 14.

Usually it is equal to period.

Range in [2; PeriodType::MAX)

method_k: RegularMethods

MA method for smoothing main value. Default is SMA.

smooth_d: PeriodType

Period for smoothing signal line value. Default is 3.

Range in [2; PeriodType::MAX)

method_d: RegularMethods

MA method for smoothing signal line value. Default is SMA.

zone: ValueType

Zone size for #1 and #2 signals.

Range in [0.0; 0.5].
