Uma sugestão para todos os membros, não use rotinas de "contagem" para fechar negócios. Por exemplo, não use algo como isto:
para (i = 0; i<t; i++)
{
if(OrderSelect(tik,SELECT_BY_TICKET)){
duplo prc = Licitação;
se (op == OP_SELL) prc = Perguntar;
CloseOrder(tik, OrderLots(), prc);
}
Se você estiver usando vários pedidos, não fechará o último pedido. Use uma rotina de "contagem regressiva". Aqui está minha discussão com os desenvolvedores de Metaquotes quando tropeçei pela primeira vez neste irritante "bug".
http://www.metaquotes.net/forum/2018/ok então como DEVERIA ser isto? e será que esta linha fará o que eu quero que ela faça?
se (prc == Bid && currentlong minorts):

for(trade=OrdersTotal()-1;trade>=0;tradee--){
enquanto eu tenho a idéia de contar para trás ao invés de contar para frente
isto é contar dois lugares corretos?
{
int tik[30], t = 0;
for(int i =0;i<OrdersTotal();i++){//------counting forward error here
if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)){
if(OrderSymbol()==Symbol() && MagicNum==OrderMagicNumber() && OrderType() == op){
tik[t] = OrderTicket(); t++;
}
}
}

{
if(OrderSelect(tik,SELECT_BY_TICKET)){
double prc = Bid;
if (op == OP_SELL) prc = Ask;
CloseOrder(tik, OrderLots(), prc);
}
}
}Eu apenas confuso sobre como mudá-los... seria...?
for(int i =0;i>OrdensTotal();i--){
e
para (i = 0; i>t; i--)
Eu ainda estou tentando colocar meu cérebro em volta da coisa do crossback.
A seguir, um exemplo de uma rotina de fechamento de baunilha simples sem sinos e apitos. Eu acho que o código é bastante simples para molhar os pés.
void CloseAll()
{
int trade;
for(trade=OrdersTotal()-1;trade>=0;trade--)
{
OrderSelect(trade,SELECT_BY_POS,MODE_TRADES);
if(OrderSymbol()!=Symbol())
continue;
if(OrderSymbol()==Symbol() && OrderMagicNumber()== MagicNum)
{
if(OrderType()==OP_BUY)
OrderClose(OrderTicket(),OrderLots(),Bid,Slippage,Blue);
if(OrderType()==OP_SELL)
OrderClose(OrderTicket(),OrderLots(),Ask,Slippage,Red);
}
}
}
O seguinte é um exemplo de uma rotina de fechamento de baunilha simples, sem sinos e apitos. Eu acho que o código é bastante simples para molhar os pés.
void CloseAll()
{
int trade;
for(trade=OrdersTotal()-1;trade>=0;trade--)
{
OrderSelect(trade,SELECT_BY_POS,MODE_TRADES);
if(OrderSymbol()!=Symbol())
continue;
if(OrderSymbol()==Symbol() && OrderMagicNumber()== MagicNum)
{
if(OrderType()==OP_BUY && currentlong > minorts)//---I want to close long positions when the ema's crossback down
OrderClose(OrderTicket(),OrderLots(),Bid,Slippage,Blue);
if(OrderType()==OP_SELL) && currentlong < minorts)//---I want to close short positions when the ema's crossback up
OrderClose(OrderTicket(),OrderLots(),Ask,Slippage,Red);
}
}
}
}
Ok baunilha simples, é mais isso...
I get these errors when I paste this in...

Onde você definiu a função"CloseOrder();"? O nome da função de fechamento que eu afixei era diferente. CloseAll()
Veja se isso resolve os problemas.
ok que faz sentido...então acho que há estratégias de fechamento concorrentes acontecendo aqui...o CloseOrder() estava relacionado com o fechamento na função de fechamento no comércio que eu nunca fui trabalhado para fazer o que eu pretendia. Então eu acho que por enquanto e para o presente propósito eu apenas apago que eh...alguém me mostrou um truque legal para desligar o código basta adicionar o "//" na frente da linha...
aqui está a coisa toda.... como é...

Certo, ainda estou esperando um e-mail para chegar. Portanto... mais alguns minutos para matar.
Você tem que cortar a função closeall e colá-la fora do laço inicial. É uma função separada. Então você tem que chamar a função closeall a partir do loop inicial onde você quer que ela feche os negócios. Acho que você tem que estudar este conceito de chamar as funções antes de ir mais longe.
