Resumo

Esta é uma estratégia de negociação baseada na ação do preço, combinada com médias móveis para identificar tendências e usar padrões de preços para entrada.

Princípios de estratégia

A estratégia baseia-se principalmente nos seguintes aspectos:

  1. Usando a EMA para julgar tendências. Quando a EMA de 89 períodos e a Hull MA são ambas vermelhas, é julgada como uma tendência de baixa, apenas curta; quando ambas são verdes, é julgada como uma tendência de alta, apenas longa; quando uma é verde e outra é vermelha, é julgada como consolidação, tanto longo quanto curto são possíveis.

  2. A estratégia reconhece várias combinações de velas como velas individuais, padrões falsos, barras internas etc. para detectar pontos de entrada potenciais.

  3. Combinando com os principais níveis de suporte/resistência para a entrada, a estratégia também incorpora níveis S/R-chave para verificar ainda mais os sinais do padrão de preços e evitar falhas de ruptura.

  4. As cores do histograma MACD são usadas para confirmar sinais de padrão de preços e melhorar a probabilidade.

  5. Mecanismo de acompanhamento da tendência: a estratégia inclui um módulo de acompanhamento da tendência para detectar com mais precisão as inversões da tendência e evitar a perseguição de altos e baixos.

  6. A definição de stop loss e take profit.

Análise das vantagens

A estratégia apresenta as seguintes vantagens:

  1. Baseado na ação dos preços, não afetado por indicadores, baseado em preços puros sem indicadores complexos, mais próximo da natureza do mercado.

  2. Combinando tendências, evitando a perseguição.

  3. Os padrões de preços combinados com o MACD verificam sinais, filtram falsos sinais, melhorando a lucratividade.

  4. O módulo de seguimento de tendências detecta tendências de um período de tempo maior, com maior potencial de lucro.

  5. A taxa de stop loss/take profit fixa ajuda a gerenciar o risco/recompensa.

Análise de riscos

A estratégia apresenta igualmente os seguintes riscos:

  1. A estratégia funciona melhor com tendências claras de médio / curto prazo. Riscos de reversão maiores sendo interrompidos. Análise de prazo maior pode ajudar a evitar.

  2. Risco de falha do padrão de preços. Os padrões de preços têm uma eficácia variável em diferentes ambientes de mercado. Alguns mercados podem causar falhas nos padrões, levando a perdas. O backtesting de vários mercados pode otimizar a seleção de padrões.

  3. Dificuldade de otimização de parâmetros. A estratégia tem múltiplos parâmetros. Diferentes combinações impactam significativamente os resultados. Extenso backtesting é necessário para encontrar parâmetros ideais. A configuração estática também corre o risco de mudanças no regime do mercado. Um mecanismo de otimização de parâmetros dinâmicos pode ajudar a resolver isso.

  4. Incapacidade de controlar o risco de negociação individual. Stop loss / take profit fixo não pode se adaptar às flutuações em cada negociação e gerenciar as taxas de risco / recompensa de negociação individual. Algoritmos de stop loss dinâmicos ou módulos de gerenciamento de risco podem ajudar.

Orientações de otimização

A estratégia pode ser melhorada nos seguintes aspectos:

  1. Introduzir aprendizado de máquina para reconhecimento de padrões mais complexos.

  2. Aumentar a adaptabilidade. Construir mecanismos de otimização de parâmetros dinâmicos para que a estratégia possa ajustar com base nas condições de mercado em tempo real em vez de configurações estáticas.

  3. Incorporar mais fatores para verificar os sinais. Adicionar mais fatores de ação de preço, como volume, brechas durante a noite, etc., para confirmar os sinais e reduzir o risco de ser preso.

  4. Introduzir gestão de risco e dimensionamento de posições. Ajustar automaticamente os tamanhos das posições com base em limiares para controlar efetivamente o stop loss de uma única negociação e otimizar as taxas de risco/recompensa.

  5. Otimizar os mecanismos de entrada. Refinar os módulos de detecção de tendências para identificar ritmos de tendência/consolidação com mais precisão, melhorando a precisão de entrada.

Conclusão

Em geral, a força central desta estratégia reside em julgamentos baseados na ação de preços, evitando a dependência de indicadores e refletindo o máximo a natureza do mercado. A combinação de tendências e indicadores melhora a lucratividade, enquanto o controle de stop loss / take profit controla o risco. Mas riscos como inversões de tendência de maior prazo, falhas de padrões de preços precisam ser abordados. Melhorias futuras podem vir do aprendizado de máquina, otimização de parâmetros dinâmicos, módulos de gerenciamento de risco, etc. para tornar a estratégia mais robusta.
