Estratégia de negociação de padrão K-line
ChaoZhang
Visão geral
Esta é uma estratégia que utiliza diferentes formas de linha K como sinais de negociação. Pode detectar 9 formas de linha comum e gerar sinais de compra e venda com base nessas formas.
Princípio da estratégia
A lógica central da estratégia é identificar as diferentes formas de linha K, incluindo a estrela-cruz, a bola, a estrela-luz, etc. Quando a forma de identificação é bullish, gera um sinal de compra; Quando a forma de identificação é bearish, gera um sinal de venda.
Por exemplo, quando se detecta uma linha K de três entidades brancas em alta, é um sinal de três trombetas brancas em alta, indicando que o mercado está em uma tendência de alta, e que, nesse momento, será gerado um sinal de compra.
Por exemplo, quando uma linha K de um longo fio negro engolve completamente a entidade anterior de um fio amarelo, forma-se a forma de IShengulfing do urso, indicando uma reversão de tendência, que gera um sinal de venda.
Análise de vantagens
Esta estratégia baseada na identificação de formas, que pode capturar pontos de reversão de curto prazo, é especialmente adequada para a negociação de linhas curtas. Identificar os sinais de formas precisas, pode capturar a reversão de preços em tempo hábil e entrar na direção de lucro.
Em comparação com estratégias de indicadores técnicos, como a média móvel simples, a estratégia de forma K-line combina o julgamento de movimentos de preços e sentimentos de mercado, e os sinais de negociação são mais precisos e confiáveis.
Análise de Riscos
A estratégia depende principalmente do julgamento preciso da forma da linha K. Se o julgamento for errado, é fácil formar sinais de negociação errados, resultando em perdas.
Além disso, nenhuma estratégia de análise técnica pode evitar completamente os riscos sistemáticos, como os efeitos da política, os eventos de cisne negro e outros que podem afetar a negociação.
Pode-se controlar o risco através de um stop loss. Quando o preço se aproxima de um limite, pode-se fazer um stop loss e sair do limite.
Direção de otimização
A variedade de formas de linha K identificadas pode ser ampliada com a adição de sinais de formas mais eficientes, como linha de arco, linha de arco invertido, linha de separação, etc., para confirmar o sinal de transação.
Pode ser filtrado em combinação com outros indicadores, evitando a produção de sinais de negociação em um ambiente de mercado incerto. Por exemplo, os sinais emitidos por indicadores como MACD, RSI e outros podem evitar sinais de baixa qualidade da forma de linha K.
Pode-se otimizar a lógica de parada de perda, quando o preço quebra uma certa amplitude na direção oposta. Ao mesmo tempo, em combinação com o indicador de taxa de flutuação, ajuste dinamicamente o intervalo de parada.
Resumir
Esta é uma estratégia de negociação de linha curta muito prática. Ela identifica as formas comuns de linha K para gerar sinais de negociação, que podem aproveitar as oportunidades de reversão de preços em curto prazo.
