Стратегия Universal MA Cross V4
Обзор
Universal MA Cross V4 — порт эксперта MetaTrader 4 «Universal MACross EA v4» на высокоуровневый API StockSharp. Алгоритм отслеживает взаимодействие быстрой и медленной скользящих средних с гибко настраиваемыми параметрами. Поддерживаются разные типы усреднения, выбор источника цены, фильтрация по часам, а также управление позицией с режимом стоп-и-разворот, защитными целями и трейлинг-стопом. Логика выполняется на завершённых свечах, полученных через подписку на тип свечей стратегии.
Торговая логика
Обработка индикаторов
- На каждой закрытой свече рассчитываются две скользящие средние. Для каждой можно задать собственный период, метод усреднения (простое, экспоненциальное, сглаженное или линейно-взвешенное) и ценовой источник (close, open, high, low, median, typical, weighted).
- Фильтр MinCrossDistancePoints требует, чтобы на свече сигнала быстая и медленная средние расходились минимум на указанное число пунктов. При включённом ConfirmedOnEntry проверка выполняется по предыдущей закрытой свече, повторяя режим «confirmed» исходного эксперта.
- Опция ReverseCondition меняет местами условия для длинных и коротких сделок без изменения индикаторных настроек.
Условия входа
- Длинная позиция открывается, когда быстрая средняя пересекает медленную снизу вверх и разница между ними не меньше MinCrossDistancePoints. Для короткой позиции требуется обратное пересечение.
- При активном StopAndReverse появление противоположного сигнала сначала закрывает текущую позицию, после чего допускается разворот.
- OneEntryPerBar не позволяет открыть больше одной позиции внутри одной свечи, стратегия запоминает время последнего входа.
- Объём заявки задаётся параметром TradeVolume и автоматически передаётся в рыночные ордера StockSharp.
Управление позицией
- StopLossPoints и TakeProfitPoints задают расстояние до стоп-лосса и тейк-профита в пунктах. Значение переводится в абсолютную цену через шаг цены инструмента. При включённом PureSar все защитные механизмы отключаются — это аналог режима «Pure SAR» в MQL-версии.
- Трейлинг-стоп повторяет оригинальный алгоритм: как только цена уходит дальше TrailingStopPoints от входа, уровень стопа переносится на то же расстояние за ценой. В режиме PureSar трейлинг не используется.
- На каждой закрытой свече стратегия проверяет, пересёк ли диапазон свечи активные уровни стопа или цели. При нарушении позиция закрывается рыночным ордером, что обеспечивает детерминированное поведение в тестах.
Фильтр торговых часов
- Флаг UseHourTrade ограничивает входы интервалом от StartHour до EndHour (0–23, границы включены). Если окончание меньше начала, окно считается переходящим через полночь. Управление уже открытой позицией (включая трейлинг) продолжает работать вне сессии, но новые входы запрещены.
Параметры
| Параметр | Описание |
|---|---|
FastMaPeriod, SlowMaPeriod |
Периоды быстрой и медленной скользящих средних. |
FastMaType, SlowMaType |
Типы усреднения: Simple, Exponential, Smoothed, LinearWeighted. |
FastPriceType, SlowPriceType |
Источники цен для каждой средней. |
StopLossPoints, TakeProfitPoints |
Расстояние до стоп-лосса и тейк-профита в пунктах (0 — отключить). |
TrailingStopPoints |
Дистанция трейлинг-стопа в пунктах (0 — не использовать). |
MinCrossDistancePoints |
Минимальная разница между средними для подтверждения сигнала. |
ReverseCondition |
Инвертировать правила для покупок и продаж. |
ConfirmedOnEntry |
Подтверждать сигналы по предыдущей свече. Отключение даёт немедленную реакцию. |
OneEntryPerBar |
Не более одного входа на свечу. |
StopAndReverse |
Закрыть текущую позицию и развернуться при противоположном сигнале. |
PureSar |
Отключить стоп-лосс, тейк-профит и трейлинг-стоп. |
UseHourTrade, StartHour, EndHour |
Ограничение торговли по часам. |
TradeVolume |
Объём рыночных сделок. |
CandleType |
Тип свечей, используемый для расчётов. |
Особенности конверсии
- Параметры расстояний заданы в пунктах, как в MetaTrader. Метод
GetPriceOffsetпереводит эти значения в абсолютные цены через шаг цены или количество знаков инструмента, сохраняя поведение оригинального советника. - Трейлинг-стоп реализован внутри стратегии, поскольку высокоуровневые стратегии StockSharp работают с завершёнными свечами. Это гарантирует воспроизводимость результатов при тестировании на свечных данных.
- По требованию заказчика предоставлена только C#-версия и многоязычная документация; Python-вариант и соответствующая папка не создавались.
