Resumo

Esta estratégia usa o indicador de tendência do Coral da LazyBear para determinar a direção da tendência do preço, identificando inversões do indicador de tendência do Coral para detectar pontos de entrada potenciais.

O mecanismo de saída utiliza o preço mais alto/mais baixo das N velas mais recentes multiplicado por um rácio risco-recompensa configurável para definir o stop loss e o take profit.

Estratégia lógica

Após determinar a direção da tendência principal com base no indicador Coral Trend, quando a cor do indicador permanece inalterada e o preço mostra um pequeno pullback na direção oposta.

As condições de entrada incluem:

A direção do indicador Coral Trend é consistente com a direção do comércio (longo=verde, curto=vermelho)
Desde a última vez que o preço atravessou completamente o indicador Coral Trend (o ponto alto da última barra excede a linha Coral Trend), houve pelo menos 1 barra com pontos baixos acima (longo) ou pontos altos abaixo (curto) do indicador Coral Trend
Uma pequena retração ocorre na direção oposta, durante a qual o preço de fechamento permanece no lado oposto da Coral Trend
Após o fim do recuo, o preço de fechamento retorna à direção de tendência principal indicada pela Coral Trend

A estratégia adopta simultaneamente o indicador ADX ou o histograma de força absoluta e o indicador HawkEye Volume como condições de confirmação da entrada.

O indicador ADX requer que o seu valor seja > 20 e aumente sobre o último 1 bar.

O Histograma de Força Absoluta requer que sua cor seja consistente com a direção do comércio (longo = azul, curto = vermelho).

O mecanismo de saída usa o preço mais alto/mais baixo das N velas mais recentes multiplicado pela relação risco-recompensa para definir o stop loss e o take profit.

Análise das vantagens

A maior vantagem desta estratégia é que, depois de determinar a direção principal da tendência usando o indicador Coral Trend, ele detecta oportunidades de entrada identificando reversões, evitando a deriva em mercados não-trending.

Além disso, esta estratégia fornece um mecanismo completo de controlo do risco, incluindo a fixação da magnitude do stop loss e o controlo da percentagem de exposição ao risco, de modo que, mesmo que as operações individuais percam dinheiro, não causará um impacto significativo no capital total.

Análise de riscos

O maior risco desta estratégia é que o uso de indicadores para julgamento de entrada pode facilmente criar ilusões, acreditando que você pode ganhar dinheiro automaticamente apenas confiando em configurações de parâmetros.

Além disso, a definição de stop loss e take profit também precisa ser apropriada. Múltiplos de take profit excessivamente grandes podem resultar em falha de take profit, enquanto stop loss excessivamente pequenos resultarão em risco excessivo. Isso precisa ser definido de acordo com a volatilidade de diferentes produtos e tolerância pessoal ao risco.

Orientações de otimização

As direcções otimizáveis desta estratégia incluem:

Ajustar os parâmetros do indicador Coral Trend para torná-lo mais sensível às alterações de preços de diferentes produtos
Tente diferentes indicadores de confirmação ou combinações de indicadores, como KDJ, MACD, etc., para tornar os sinais de entrada mais precisos
De acordo com a volatilidade dos diferentes produtos, ajustar o método de cálculo do stop loss e do take profit para obter um melhor controlo do risco
Adicionar um módulo de gestão de fundos para ajustar a quantidade de ordem única com base no número de posições mantidas, controlando efetivamente as perdas globais
Adicionar um módulo de controlo do tempo de negociação para que a estratégia seja executada apenas durante períodos específicos para evitar perdas durante períodos de volatilidade extrema

Conclusão

Esta estratégia usa primeiro a Coral Trend para determinar a tendência de médio e longo prazo dos preços, em seguida, julgando sua reversão, combinada com sinais de Confirmação para filtrar falhas, ela constrói uma estratégia de tendência relativamente confiável. Ao mesmo tempo, as configurações de controle de risco melhoradas também permitem que esta estratégia seja executada por um longo tempo com capital estável. Com a otimização adicional de parâmetros e módulos, espera-se que esta estratégia se adapte a mais produtos e tenha melhor estabilidade e lucratividade.
