Estratégia Adx Bollinger
Estratégia baseada nos indicadores ADX e Bandas de Bollinger. Entra comprado quando ADX > 25 e o preço fecha abaixo da banda inferior de Bollinger. Entra vendido quando ADX > 25 e o preço fecha acima da banda superior de Bollinger.
Os testes indicam um retorno anual médio de aproximadamente 115%. Funciona melhor no mercado de ações.
As rupturas das Bandas de Bollinger filtradas com ADX garantem que o preço está rompendo com força. O sistema opera na direção do rompimento.
Adequado para ambientes de alta volatilidade. Um stop baseado em ATR reduz o risco de queda.
Detalhes
- Critérios de entrada:
- Comprado:
Close < LowerBand && ADX > 25 - Vendido:
Close > UpperBand && ADX > 25
- Comprado:
- Comprado/Vendido: Ambos
- Critérios de saída: O preço retorna à banda média
- Stops: Baseado em ATR usando
AtrMultiplier - Valores padrão:
AdxPeriod= 14AdxThreshold= 25BollingerPeriod= 20BollingerDeviation= 2.0mAtrPeriod= 14AtrMultiplier= 2.0mCandleType= TimeSpan.FromMinutes(5).TimeFrame() O 25 das regras é o padrão de AdxThreshold. Como mostram os critérios de entrada, a saída na banda média e a categoria Mean reversion, o rompimento de uma banda com ADX forte é operado contra. O stop fica a AtrMultiplier ATR (AtrPeriod) do fechamento de entrada e é verificado nos fechamentos dos candles. Um sinal de entrada contra uma posição aberta a inverte.
- Filtros:
- Categoria: Reversão à média
- Direção: Ambos
- Indicadores: ADX, Bollinger Bands
- Stops: Sim
- Complexidade: Intermediário
- Período: Médio prazo
- Sazonalidade: Não
- Redes neurais: Não
- Divergência: Não
- Nível de risco: Médio
