Multiple OrderSend

[Dua Yong Rew]

Hi all,

I tried to code 2 ordersend together but only one will be sent

OrderSend(Symbol(), OP_BUY, LotSize(Risk), Ask, 3, Ask - StopLoss, 0, "B", 100, 0, Blue);

OrderSend(Symbol(), OP_BUY, LotSize(Risk), Ask, 3, Ask - StopLoss, Ask + TakeProfit, "B", 200, 0, Blue);

Is there any work ard because my EA will trailing the first one and the second will be based on takeprofit close.

Thanks

I suppose so.

Any examples that I could follow?

As ronaldosim is implying, it's just a question of checking GetLastError() if an order fails - i.e. if the ticket number returned by OrderSend is <= 0.

Based on your example code, I'd guess that your problem is one of the following three cases, in descending order of probability:

• By the time you come to place the second order, the market has moved and the Ask price is no longer valid. If so, you will see error #129. You can solve this either by doing a RefreshRates() to update the value of Ask, or by using MarketInfo(Symbol(), MODE_ASK) instead of Ask.
  
• The t/p on the second order is tighter than your broker allows. If so, you will see error #130.
  
• MetaTrader's trading thread is busy. If so, you'll probably see error #146.

can this function work if i put them in between

ToTrade();
Ticket = OrderSend(Symbol(), OP_BUY, LotSize(Risk), Ask, 3, Ask - StopLoss, Ask + TakeProfit, "RangerBreak.B", 10703234, 0, Blue);
if(Ticket < 0) Print("Error in OrderSend : ", GetLastError());

ToTrade();
Ticket = OrderSend(Symbol(), OP_BUY, LotSize(Risk), Ask, 3, Ask - StopLoss, 0, "RangerBreak.B", 10703234, 0, Blue);
if(Ticket < 0) Print("Error in OrderSend : ", GetLastError());

void ToTrade()
{
for(int i = 0; i < 60; i++)
{
if(IsTradeAllowed() == false || IsTradeContextBusy() == true)
{
Sleep(1000);
}
else
{
RefreshRates();
break;
}
}
}

i would prefer this than ToTrade()

while(IsTradeContextBusy()) {Print("Trade context is busy. Please wait");}
if (IsTradeAllowed())
{

Send yr orders

}

then if IsTradeAllowed() is false and passed the condition to buy?

If you're concerned about error #146 (trade context busy), I'd have a look at the suggestions in 'Error 146 ("Trade context busy") and How to Deal with It'. Under heavy load (e.g. hundreds/thousands of orders per hour) I consistently get serious problems in MetaTrader if I don't use the techniques described in sections 5 and 6 of this article - albeit at the cost of implementing what's effectively co-operative multi-tasking between EAs.

But I'd be surprised from your example code if error #146 is your problem. It still looks more likely to be the ask price being out of date by the time you come to place the second order.

What happens if you use MarketInfo(Symbol(), MODE_ASK) instead of Ask?

just to check

OrderSend(Symbol(), OP_BUY, LotSize(Risk), Ask, 3, Ask - StopLoss, 0, "B", 100, 0, Blue);

my slippage is 3 points. but does it work for a 5 decimal broker like alpari?
