Olá, estou tentando criar uma estratégia baseada no indicador zigzag color. O indicador zigzag plota linhas diagonais crescentes e decrescentes conforme o movimento do gráfico e dos parâmetros prè selecionados.
Gostaria que meu programa realizasse uma compra quando a linha vermelha (zigzag color) ou linha decrescente (zigzag) aparecesse no gráfico e uma venda somente quando a linha verde (zigzag color) ou a linha crescente (zigzag) aparecesse.
Dito isso, ainda não consegui puxar o Buffer de cor!
Poderiam me ajudar ?
