DVD Estrategia de 100-50 céntimos

Descripción general

La estrategia DVD de 100-50 centavos es un sistema de orden límite contrario adaptado del asesor experto MT4 original. La lógica evalúa el mercado en cuatro períodos de tiempo (M1, M30, H1, D1) y califica las configuraciones potenciales antes de estacionar órdenes límite de compra o venta alrededor de la cuadrícula de precios de "100 niveles" más cercana. Cuando se ejecuta la orden límite, la estrategia gestiona la posición con niveles de stop-loss y take-profit precalculados.

Indicadores y datos

  • RAVI (Índice de verificación de acción de rango) en H1 y D1, calculado con SMA(2) y SMA(24) sobre el precio de apertura.
  • Datos de velas sin procesar en M1, M30 y H1 para filtros de patrones como rechazo de picos, comprobaciones de consolidación y pruebas de impulso.
  • Redondeo de la cuadrícula de precios que ajusta el precio actual al nivel 100 más cercano usando un redondeo de dos decimales y un desplazamiento configurable de 0,1 pips.

Lógica de entrada

  1. Calcule el precio redondeado "Nivel 100" redondeando el último M1 cerca de dos decimales y desplazándolo en PointFromLevelGoPips (predeterminado 50 → 5 pips).
  2. Inicialice una puntuación interna (BAL) en 0 y sume/reste puntos según:
    • Filtro de tendencia: agregue 10 puntos cuando H1 RAVI esté por debajo de cero para configuraciones largas o por encima de cero para configuraciones cortas.
    • Confirmación de pico por hora: agregue 7 puntos cuando los dos máximos/mínimos del primer semestre anteriores superen la cuadrícula en RiseFilterPips.
    • Alineación de la estructura: agregue 45 puntos cuando el cierre actual de M1 vuelva a cruzar el nivel y los últimos tres mínimos/máximos de H1 permanezcan por encima/por debajo del colchón de seguridad (PointFromLevelGoPips ± 30 * 0.1 pip).
    • Guardias de volatilidad: reste 50 puntos si los máximos/mínimos recientes de M1 exceden HighLevelPips (predeterminado 600 → 60 pips) o si aparecen ráfagas rápidas de impulso mientras el D1 RAVI confirma un fuerte régimen direccional.
    • Confirmación de ruptura: reste 50 puntos si las últimas 15 velas H1 nunca cruzaron el umbral LowLevel2Pips.
    • Filtro de consolidación: reste 50 puntos si las últimas ocho velas M30 permanecen dentro de la banda LowLevelPips.
  3. Realice una orden limitada solo cuando la puntuación final sea de al menos 50 y no exista otra exposición (posición u orden pendiente).

Colocación de pedidos

  • Límite de compra: 10 pips por debajo del último cierre de M1. El stop-loss está StopLossPips por debajo del precio límite, la toma de ganancias está TakeProfitPips por encima de él. Cuando el D1 RAVI muestra una escalera ascendente entre -1 y +5 durante los últimos cuatro días, la toma de ganancias recibe una extensión adicional de 25 pips.
  • Límite de venta: 7 pips por encima del último cierre de M1 con reglas de objetivo y stop simétricas. Cuando el D1 RAVI muestra una escalera descendente entre -5 y -1, el objetivo se extiende 25 pips.
  • Los pedidos pendientes caducan automáticamente después de OrderExpiryMinutes (20 minutos predeterminado). Cuando se cancela una orden, los niveles de protección almacenados se restablecen.

Gestión de Puestos

  • Una vez completada, la estrategia mantiene internamente los valores almacenados de stop-loss y take-profit y emite órdenes de salida del mercado cuando el precio toca cualquiera de los niveles.
  • No se aplica ningún trailing stop en la versión portada; el EA original deshabilitó la lógica final de forma predeterminada.
  • Las nuevas operaciones se bloquean mientras exista una posición activa o una orden límite pendiente.

Gestión monetaria

  • Cuando UseMoneyManagement está habilitado, el tamaño del lote imita la implementación de MT4: escala en TradeSizePercent del capital actual, se ajusta para cuentas mini y fija el resultado en [0.1, MaxVolume] (mini) o [1, MaxVolume] (estándar).
  • Deshabilitar la administración del dinero fuerza un volumen fijo controlado por el parámetro FixedVolume.
  • La negociación se detiene cuando el capital de la cartera cae por debajo de MarginCutoff.

Notas de uso

  • La conversión se basa en las velas terminadas de cada período; asegúrese de que el flujo de datos históricos proporcione velas M1, M30, H1 y D1 sincronizadas.
  • El stop y el objetivo de protección se ejecutan con órdenes de mercado para reflejar el comportamiento MT4 de los valores SL/TP adjuntos.
  • Debido a que la lógica es sensible al tamaño del pip, verifique que las propiedades PriceStep y Decimals del instrumento describan correctamente el formato de cotización.
