Boa tarde, Alguém pode sugerir uma solução para este problema? Há um código com entrada na M15, mas o sinal de H1 é levado em conta. Enquanto há um sinal na H1, na M15 o indicador dá vários sinais. A questão é como limitá-lo a um (ou seja, o primeiro sinal).
k=0;
for (i=OrdensTotal()-1;i>=0;i--)

RefreshRates();
if(OrderSelect (i, SELECT_BY_POS, MODE_TRADES) == true) a = 0;
if (OrderSymbol() == Symbol() && OrderMagicNumber() == Magic) k++;
}
if( stM1 >= 80 && stM0 < 80 && stH0 < 30 && k==0 && opp != Tempo[0]) // venda
