Primeiro

OrderOfSymbol=CounterOrderTradeType(-1);

deve ser colocado aqui.

void OnTick()

Eu consertarei o resto.

Bom dia a todos. Tenho um EA que sinaliza quando a linha de tendência e a linhahorizontal cruzam uma determinada cor. Decidi refazê-lo de forma a sinalizar quando a linha de tendência e a linha horizontal cruzam um certo estilo. Funcionou. Mas eu preciso dele para sinalizar quando uma linha de tendência cruza apenas a viga à direita. Entendo que tenho de acrescentar

OBJPROP_RAY_RIGHT

mas eu não sei onde ou como. Obrigado de antemão.
