3 values

• Upper bound

Range of values is the same as the range of the source values.

• Lower bound

Range of values is the same as the range of the source values.Action

• Raw Source2 value

1 signal

• Signal 1 appears when Source2 value crosses bounds. When Source2 value crosses upper bound upwards, returns full sell signal. When Source2 value crosses lower bound downwards, returns full buy signal.

Fields

ma: M

Main moving average type.

Default is SMA(20).

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

k: ValueType

Bound relative size. Default is 0.1.

Range in (0.0; +inf).

source: Source

Source value type for bounds. Default is Close.

source2: Source

Source2 value type for actual price. Default is Close.
