Эта стратегия использует индикатор SuperTrend для определения ценового тренда и включает в себя механизм остановки потерь для тренда после торговли. SuperTrend построен из двух скользящих средних.
Вычислить DEMA быстрых и медленных линий. Направление SuperTrend определяется на основе разницы между двумя линиями. В восходящих тенденциях быстрое пересечение линии выше медленной линии сигнализирует о длинном входе. В нисходящих тенденциях быстрое пересечение линии ниже медленной линии сигнализирует о коротком входе. После входа устанавливается линия остановки потери. Если потеря достигает процента остановки потери, позиция закрывается.
Риски могут быть смягчены сокращением скользящих средних периодов, оптимизацией процента стоп-лосса, сокращением частоты торгов и т.д.
Эта простая стратегия использует индикаторы для направления тренда и стоп-лосс для контроля риска, подходящий для внутридневной торговли.

// This script has been optimized for the 1 hr candle window view.
// An older Pine2 ancestor of this script suffered from repainting issues when
// viewing in lower resolutions than the res/2 parameter.
// running this in Pine3 mode seems to fix those problems, see https://www.tradingview.com/wiki/Pine_Script:_Release_Notes#Pine_Version_3 and https://backtest-rookies.com/2017/11/29/tradingview-indicator-repainting/ for references on the problem.
//
// There does seem to be ocassional repainting that affects backtrading here though, somehow.. and i'm not sure how to fix it. V3 SHOULD have made it impossible. Any help appreciated.
//
// Also note that the length of the DEMA sampling shouldn't be longer than a
// candle, which could happen if you made resolution > chartres^2. For example,
// a chartres=5min and a res=30 setting would cause sampling = 6, which is longer
// than the length of a candle (5 min, b/c chartres=5 min)
