Estratégia Limits RSI Momentum Bot

Resumo

Esta estratégia coloca ordens limitadas com base nos indicadores de Índice de Força Relativa (RSI) e Momentum. Seu objetivo é comprar com descontos e vender com prêmios usando ordens pendentes em vez de execuções a mercado.

Regras de Trading

  • Opera apenas durante a janela de tempo especificada.
  • Em cada vela finalizada, os valores de RSI e Momentum são calculados.
  • Uma ordem limitada de compra é colocada abaixo da abertura da vela quando RSI e Momentum estão ambos abaixo de seus limiares de compra.
  • Uma ordem limitada de venda é colocada acima da abertura da vela quando RSI e Momentum estão ambos acima de seus limiares de venda.
  • Quando uma posição é aberta, a ordem pendente oposta é cancelada.
  • Stop-loss e take-profit são gerenciados automaticamente via StartProtection.

Parâmetros

  • Volume – volume da ordem.
  • LimitOrderDistance – distância em passos de preço da abertura da vela para colocar ordens pendentes.
  • TakeProfit – objetivo de lucro em passos de preço.
  • StopLoss – limite de perda em passos de preço.
  • RsiPeriod – período para cálculo do RSI.
  • RsiBuyRestrict / RsiSellRestrict – limiares de RSI que permitem entradas compradas ou vendidas.
  • MomentumPeriod – período para cálculo do Momentum.
  • MomentumBuyRestrict / MomentumSellRestrict – limiares de Momentum para entradas compradas ou vendidas.
  • StartTime / EndTime – limites da sessão de trading.
  • CandleType – intervalo de vela usado para cálculos de indicadores.

Observações

A estratégia é convertida do script MQL4 "The Limits Bot with RSI & Momentum" e usa a API de alto nível do StockSharp.
