Esta estratégia implementa a negociação de padrões de preço identificando padrões de velas. Ele procura o padrão de pinbar mais próximo e vai longo ou curto com base no sinal. Os comerciantes podem definir múltiplos de take profit e stop loss.
Identifique se a vela atual atende aos requisitos da barra de pinhas - corpo na metade inferior, fechado e aberto perto de baixo. O sinal longo é o oposto - corpo na metade superior, fechado / aberto perto de alto. Encontre a última vela de sinal e calcule a altura do corpo. Configure take profit para N vezes a altura e stop loss para M vezes a altura (M < N).
Depois de entrar, comece a seguir o stop, continue a mover-se, tire lucro em direção ao lucro, mantendo o stop loss, até que seja atingido.
Os riscos podem ser reduzidos através da otimização de parâmetros, da adição de indicadores, etc.
Esta estratégia identifica oportunidades através do reconhecimento de padrões com bons resultados de backtest. Paradas razoáveis controlam o risco comercial.
