As pessoas dizem-me o que estou a fazer mal, porquê dois indicadores iRSI,iCCI não causa problema, mas os muwings e BB dão um aviso (possível perda de dados devido ao indicador de conversão de tipo.mqh )

Eu escreveria o destacado da seguinte forma:

Do fundo do meu coração...!!! )
Funcionou, funcionou!
Obrigado Alexei!!!!!!!!!!!!!!
Bom dia. Pode sugerir um EA para MT5? Pode sugerir um EA com uma paragem de percurso? De preferênciaum SCALPER ou um que funcione com NOVIDADES ou outro . Obrigado de antemão.
Por favor explique como instalar o indicador adquirido no terminal, porque o comprei, mas não o consigo activar, não sei qual é o problema?
Esclareça: comprou no Market?
Após a compra, cliquei em "Instalar no terminal" e depois fui para o terminal comercial, mas nada aconteceu, o indicador não apareceu
