Resumo

A estratégia Multi-Bar Direction identifica os sinais de reversão de tendência, calculando a probabilidade de várias barras se moverem na mesma direção.

Estratégia lógica

A estratégia primeiro define o horário de início e fim para a extração de dados históricos. As horas de negociação são configuradas para identificar velas qualificadas. Ele calcula a probabilidade de ascensões ou descidas consecutivas dentro de 2 a 7 velas. Os sinais de negociação são gerados quando a relação de ascensão ou descida excede um limiar.

Por exemplo, se a probabilidade de tendência de baixa em 3 velas for inferior a 50%, as 3 velas atuais atendem à condição e um sinal de compra é gerado.

A lógica específica é a seguinte:

Definir um intervalo de tempo de backtest, incluindo data de início, data de fim, horário de negociação.
Conte o número de subidas ou descidas da mesma direção dentro de 2 a 7 candelabros.
Calcule a probabilidade de continuação para cima ou para baixo entre candelabros adjacentes.
Se a probabilidade for inferior a 50%, os candelabros correntes correspondem ao padrão de reversão.
Gerar sinais de compra ou venda durante as horas de negociação.
Testes para validar a estratégia.

Vantagens

Evite sinais falsos considerando várias probabilidades de candelabros.
Contagem de barras personalizável para identificar sinais de reversão em diferentes prazos.
Horários de negociação claros evitam sinais impróprios.
Display de estatísticas intuitivas para avaliação do desempenho.
Muitos parâmetros otimizáveis adequados para diferentes mercados.

Riscos

A contagem de barras não pode determinar completamente os pontos de reversão da tendência.
A longa duração das estatísticas pode perder oportunidades de negociação a curto prazo.
O limiar estático é afectado pela volatilidade do mercado, sendo necessário um ajustamento dinâmico.
A selecção do período de ensaio posterior pode causar sobreajuste.

Possíveis soluções:

Otimize a contagem de barras para diferentes prazos.
Incorporar outros indicadores.
Adotar limiares dinâmicos com base na volatilidade do mercado.
Expandir o período de backtest e executar múltiplos backtests.

Orientações de otimização

A estratégia pode ser otimizada nos seguintes aspectos:

Otimizar a contagem de barras de 2 a 10 e selecionar o parâmetro ideal.
Prazo de reversão do ensaio de 40% para 60% tendo em conta as alterações do mercado.
Adicionar stop loss após a geração do sinal para limitar o risco.
Incorporar outros indicadores como RSI para validar sinais.
Adicione mais produtos como futuros e forex para testes de parâmetros.
Ajuste incremental de parâmetros para encontrar combinações ideais.
Aplicar modelos de aprendizagem de máquina para encontrar parâmetros ideais automaticamente.

Conclusão

A estratégia Multi-Bar Direction identifica potenciais sinais de reversão por meio da análise estatística das probabilidades do candelabro. Mas o desempenho depende do ajuste de parâmetros com base em otimizações suficientes. Além disso, os sinais de reversão têm riscos de julgamento errado e precisam de validação.
