Resumo

Esta é uma estratégia que utiliza diferentes padrões de velas como sinais de negociação.

Estratégia lógica

A lógica central desta estratégia é identificar diferentes padrões de velas, incluindo Doji, Hammer, Morning Star etc. Quando um padrão de alta é identificado, um sinal de compra será acionado.

Por exemplo, quando três velas brancas consecutivas com altas e baixas mais altas são detectadas, ele dá o sinal de Three White Soldiers indicando um mercado de alta.

Também, por exemplo, quando uma vela baixa longa engole completamente o corpo da vela alta anterior, ela forma um padrão de Engulfamento Baixo, implicando uma inversão de tendência.

Análise das vantagens

Este tipo de estratégias de reconhecimento de padrões pode capturar pontos de reversão de curto prazo e é especialmente adequado para negociação de curto prazo.

Em comparação com estratégias de indicadores técnicos simples como médias móveis, a estratégia de padrão de velas incorpora o julgamento da ação de preços e do sentimento do mercado, tornando os sinais de negociação mais precisos e confiáveis.

Análise de riscos

Esta estratégia baseia-se principalmente na identificação precisa de padrões de velas.

Além disso, qualquer estratégia de análise técnica não pode evitar completamente os riscos sistémicos, como os impactos das políticas, os eventos do cisne negro, etc., que podem influenciar a negociação.

Quando o preço atravessa uma faixa em direção oposta, o stop loss pode ser desencadeado para sair de posições em tempo hábil.

Orientações de otimização

Padrões de candelabro mais eficientes podem ser adicionados para confirmação de sinal, como martelo, martelo invertido, linhas de separação, etc.

Outros indicadores podem ser incorporados para filtragem de sinais, evitando a captação de sinais em um ambiente de mercado incerto.

A lógica de stop loss pode ser otimizada para ser acionada quando o preço sai de uma faixa em direção à direção oposta.

Resumo

Esta é uma estratégia de negociação de curto prazo muito prática. Identifica padrões de velas comuns para gerar sinais de negociação e capturar oportunidades de reversão de curto prazo. Também precisa notar riscos potenciais e otimizar adequadamente para controlar os riscos e melhorar a eficiência.
