Tag: loop

Boa noite. A seguinte linguagem é MQL5. Estou a criar um robô para o MetaTrader 5. Eu criei depois de muitas horas o código que aparecer a seguir. Eu na altura fiz os comentários em inglês tal e qual como no tutorial pois o vídeo estava em inglês. O meu objetivo é fazer com que uma ordem BUY seja criada sempre que o valor de RSI(Relative Strenght Index) passe a ser maior que 70, e mal passe a ser menor que 70, que crie uma ordem SELL, deletando a ordem anterior. Como a estratégia vai sempre responder aos valores de RSI, ela não precisa de Stop Loss ou Take Profit. Tem algumas coisas que não sei o que fazem ou se realmente são necessárias. Eu gostava de saber o que fiz errado.
Obrigado a quem poder ajudar.
