Estratégia do Trail SL Manager

Resumo

Trail SL Manager é uma estratégia utilitária que reproduz o comportamento do especialista MetaTrader trailSL original. Não abre negociações por conta própria. Em vez disso, supervisiona as posições existentes e ajusta dinamicamente os seus níveis de parada de proteção. A lógica reflete o script de origem: primeiro, o stop é pressionado para atingir o ponto de equilíbrio quando o preço avança em um valor configurável e, em seguida, um algoritmo de rastreamento incremental continua bloqueando os lucros à medida que a tendência continua.

Como funciona

  1. Assina o fluxo de velas configurado para monitorar barras finalizadas.
  2. Rastreia o preço médio de entrada e a direção da posição atual.
  3. Quando o preço se move a favor da negociação em BreakEvenTriggerPoints, o stop é empurrado para o preço de entrada mais um deslocamento opcional.
  4. Após a ativação do ponto de equilíbrio, ou imediatamente se permitido, a estratégia aumenta o stop em TrailOffsetPoints a cada TrailStepPoints até que o preço reverta e feche a posição no mercado.

As regras finais são calculadas com a mesma aritmética baseada em pontos da versão MetaTrader, portanto, o comportamento permanece familiar para os traders que migram para StockSharp.

Parâmetros

Nome Descrição Padrão
EnableBreakEven Permite mover o stop para atingir o ponto de equilíbrio quando a negociação se tornar lucrativa. true
BreakEvenTriggerPoints Distância de lucro em pontos necessários para ativar o movimento de equilíbrio. 20
BreakEvenOffsetPoints Pontos adicionais adicionados ao preço de entrada quando o ponto de equilíbrio é executado. 10
EnableTrailing Alterna a lógica do trailing stop. true
TrailAfterBreakEven Se true, o rastreamento começa somente após o ajuste do ponto de equilíbrio. true
TrailStartPoints Lucro mínimo em pontos antes do trailing é permitido. 40
TrailStepPoints Etapa de lucro entre recálculos finais. 10
TrailOffsetPoints Pontos adicionados à parada em cada etapa final. 10
InitialStopPoints Distância da parada de proteção inicial quando surge uma nova posição. 200
CandleType Assinatura de vela usada para monitorar alterações de preços. 1 Minute

Uso

  1. Anexe a estratégia a um ambiente onde as entradas sejam geradas por outra estratégia ou manualmente.
  2. Configure os limites baseados em pontos para corresponder à volatilidade do símbolo e aos requisitos do corretor.
  3. Inicie a estratégia para que ela possa monitorar as velas finalizadas e ajustar os stops automaticamente.
  4. Monitore os desenhos do gráfico para ver como os níveis de stop evoluem a cada passo final.

Nota: A estratégia fecha posições com ordens de mercado quando o trailing stop simulado é violado. Adicione proteção específica para exchanges (como ordens stop reais), se exigido pelo seu fluxo de trabalho.
