O Commodity Channel Index (CCI) mede o quanto o preço se afasta de sua média estatística. Esta estratégia entra quando o CCI se desvia de sua própria média por uma grande margem, esperando um retorno rápido assim que o momentum diminui.
Os testes indicam um retorno anual médio de aproximadamente 151%. Funciona melhor no mercado de ações.
Uma operação comprada ocorre quando o CCI cai abaixo da média menos DeviationMultiplier vezes o desvio padrão. Uma operação vendida é aberta quando o CCI sobe acima da média mais esse multiplicador. A posição é fechada quando o CCI cruza de volta pelo valor médio.
Este sistema é adequado para traders de curto prazo que preferem configurações contrárias. Um stop-loss baseado em movimento percentual ajuda a limitar o risco se o mercado não conseguir reverter rapidamente.
Detalhes
- Critérios de entrada:
- Comprado: CCI < Avg - DeviationMultiplier * StdDev
- Vendido: CCI > Avg + DeviationMultiplier * StdDev
- Comprado/Vendido: Ambos os lados.
- Critérios de saída:
- Comprado: Sair quando CCI > Avg
- Vendido: Sair quando CCI < Avg
- Stops: Sim, stop-loss percentual.
- Valores padrão:
CciPeriod = 20
AveragePeriod = 20
DeviationMultiplier = 2
StopLossPercent = 2
CandleType = TimeSpan.FromMinutes(5)
Avg e StdDev são a média e o desvio padrão dos últimos AveragePeriod valores de CCI, incluindo o atual. O stop é um StopLossPercent fixo do preço de entrada, vigiado também entre os candles; 0 o desativa. Um sinal de entrada contra uma posição aberta a inverte.
- Filtros:
- Categoria: Mean reversion
- Direção: Ambos
- Indicadores: CCI
- Stops: Sim
- Complexidade: Intermediário
- Período: Intradiário
- Sazonalidade: Não
- Redes neurais: Não
- Divergência: Não
- Nível de risco: Médio
