Funções para quem programa EA...
Estava aqui à procura de de uma função, e deparei-me com um tópico que já tinha deixado, noutro fórum, altura que ainda lá escrevia...
Mas como disponibilizei duas funções publicamente, queria deixar também aqui neste fórum, para quem se quer dedicar a estas lides.
O tópico original está em:
-
http://caldeiraodebolsa.jornaldenegocios.pt/viewtopic.php?t=79891&highlight=(têm que aceder à página 2, para ver as funções disponibilizadas)
As funções que disponibilizei na altura:
Utilizar esta função para ter o stoploss e o takeprofit "escondido da corretora"
