Estratégia de IA do Cyberia Trader

Esta estratégia é uma conversão StockSharp do consultor especialista CyberiaTrader.mq4 (build 8553). O programa MQL original mistura um mecanismo de probabilidade com uma coleção de filtros de tendência opcionais. A porta C# mantém a mesma estrutura: um modelo de probabilidade pesquisa para o período de amostragem mais confiável e então opcionais MACD, EMA e filtros de reversão podem vetar negociações.

Indicadores e Modelo Interno

  • Probability Engine – itera períodos de amostragem de candidatos (MaxPeriod) e avalia SamplesPerPeriod segmentos históricos. Para cada período o mecanismo calcula:
    • Direção da decisão (compra/venda/flat) com base em velas consecutivas de alta/baixa de um minuto espaçadas pelo período de amostragem.
    • Amplitudes médias de "possibilidade" para resultados de compra, venda e indefinidos e a parcela de resultados bem-sucedidos acima SpreadThreshold.
    • Índices de sucesso que selecionam o período de melhor desempenho.
  • EMA Filtro de tendência – média móvel exponencial opcional (EnableMa) que bloqueia negociações contra a inclinação atual.
  • MACD Filtro – convergência/divergência de média móvel opcional (EnableMacd) que proíbe a negociação contra o impulso.
  • Detector de reversão – detector de pico opcional (EnableReversalDetector) que inverte as permissões quando as probabilidades aumentam ReversalFactor múltiplos de suas médias.

Parâmetros

Nome Descrição
MaxPeriod Maior passo de amostragem inspecionado pelo mecanismo de probabilidade.
SamplesPerPeriod Número de segmentos processados por período candidato (espelha o MQL ValuesPeriodCount).
SpreadThreshold Amplitude mínima que conta como um resultado de probabilidade bem-sucedido.
EnableCyberiaLogic Ativa as opções de probabilidade da Cyberia que podem desativar compras ou vendas.
EnableMacd Ativa o filtro de impulso MACD.
EnableMa Ativa o filtro de inclinação EMA.
EnableReversalDetector Ativa as permissões de alternância do detector de reversão em picos extremos.
MaPeriod Comprimento EMA usado pelo filtro de tendência.
MacdFast / MacdSlow / MacdSignal MACD EMA rápida, EMA lenta e períodos de sinal.
ReversalFactor Multiplicador que aciona o detector de reversão.
CandleType Tipo de dados Candle processado pelo modelo (padrão 1 minuto).
TakeProfitPercent Take Profit de proteção opcional expresso como uma porcentagem.
StopLossPercent Stop loss de proteção opcional expresso em porcentagem.

Lógica de negociação

  1. Cada vela concluída atualiza a fila do histórico local e recalcula estatísticas de probabilidade para cada período de 1 a MaxPeriod. O período com maior taxa de sucesso torna-se a configuração ativa.
  2. A lógica da Cyberia define sinalizadores DisableBuy/DisableSell usando as mesmas comparações do código MQL:
    • Compara as possibilidades médias de compra/venda e suas variantes ponderadas pelo sucesso quando o período aumenta ou diminui.
    • Desativa entradas se novas possibilidades excederem o dobro de suas médias de sucesso.
  3. Filtros opcionais são aplicados na ordem: MACD, EMA inclinação e, em seguida, o detector de reversão.
  4. Quando nenhuma posição está aberta, a estratégia entra se a decisão atual for de compra (ou venda) e a possibilidade correspondente exceder sua média de sucesso enquanto a direção oposta está desativada.
  5. Enquanto existir uma posição, o código verifica as mesmas condições para fechar quando o mecanismo de probabilidade muda ou quando os filtros proíbem a posição. direção atual.
  6. StartProtection reproduz os blocos originais de gerenciamento de dinheiro quando parâmetros de risco diferentes de zero são fornecidos.

Notas sobre a conversão

  • A porta mantém os cálculos estatísticos, mas substitui a verificação de spread baseada em ticks pelo configurável SpreadThreshold.
  • O dimensionamento automático de lote e o diagnóstico de equilíbrio do script MQL não são implementados; O volume de StockSharp é controlado por meio de Volume.
  • Os módulos MoneyTrain e Pipsator são condensados na lógica unificada de entrada/saída descrita acima para corresponder ao uso de API de alto nível.
  • A estratégia adiciona desenho de gráfico para velas, EMA e MACD para facilitar a validação no designer.
