Indicator

interface Indicator<TIn> : IndicatorOutput

Write side of IndicatorOutput — fed by the engine's binding layer on each tick or candle close. Implementations are stateful and single-threaded; the engine drives one indicator from one stream alias.

Concrete catalog entries live under com.qkt.indicators.catalog and com.qkt.indicators.range; the DSL surface is the IndicatorRegistry.
