Olá comerciantes
Este é um algoritmo simples para uma estratégia Tradingview rastreando uma convergência de 2 indicadores não relacionados.
A convergência é a solução para os meus problemas comerciais. É um quebra-cabeça com infinitas possibilidades e apenas algumas combinações de trabalho.
Aqui está um que eu gosto.
Definição
Leva os cadernos e um pouco de café (bom para concentração).
O padrão de engulfamento é um padrão de inversão de duas velas. A segunda vela engloba completamente o corpo real da primeira, sem considerar o comprimento das sombras da cauda.
O padrão de Engulfing de alta aparece em uma tendência de queda e é uma combinação de uma vela vermelha seguida por uma vela verde maior O padrão de Engulfing de baixa aparece em uma tendência de baixa e é uma combinação de uma vela verde seguida por uma vela vermelha maior

Estamos entediados senhor... qual é o sentido de tudo isto?
Em resumo, um engulfing é um padrão para rastrear reversões. Adicionando os filtros de preço versus média móvel permite rastrear reversões com impulsos (metade da audiência desmaiou porque isso é muito incrível)
Está bem, senhor. Apanhou o meu interesse.
Incluí alguns filtros de backtest:
Tudo de bom. Dave.
