Esta abordagem usa o Hurst Exponent para detectar quando um mercado está se comportando de maneira de reversão à média. Valores abaixo de 0,5 sugerem que o preço tende a retornar ao seu valor médio, criando oportunidades para operar contra os extremos.
Os testes indicam um retorno anual médio de aproximadamente 121%. Funciona melhor no mercado de criptomoedas.
Uma posição comprada é aberta quando o Hurst Exponent está abaixo de HurstThreshold e o preço fecha abaixo de uma média móvel. Uma posição vendida ocorre quando o valor Hurst está abaixo de HurstThreshold e o preço fecha acima da média. As posições são encerradas quando o preço retorna à linha de média ou o Hurst Exponent sobe acima do limiar.
A estratégia é adequada para traders que preferem tendências estatísticas a tendências fortes. Um stop-loss de proteção protege contra movimentos prolongados que não conseguem reverter.
Detalhes
- Critérios de entrada:
- Comprado: Hurst < HurstThreshold && Close < MA
- Vendido: Hurst < HurstThreshold && Close > MA
- Comprado/Vendido: Ambos os lados.
- Critérios de saída:
- Comprado: Sair quando Close >= MA ou Hurst > HurstThreshold
- Vendido: Sair quando Close <= MA ou Hurst > HurstThreshold
- Stops: Sim, stop-loss percentual.
- Valores padrão:
HurstPeriod = 100
AveragePeriod = 20
HurstThreshold = 0.7
StopLossPercent = 2
As regras citam 0.5, o limite teórico da reversão à média, mas a estimativa R/S sobre 100 candles de cinco minutos nunca caiu abaixo de cerca de 0.65 no histórico de BTC e TON usado para testar os exemplos, então a regra não podia operar; HurstThreshold torna o nível um ajuste com valor padrão 0.7. MA é a média móvel simples de AveragePeriod. 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.
