How does expiration on pending order works?
 
I have found this line of code but it is not creating a buy limit order if i use this code

Here's a code snipit to set expiration time to 10 min:

PHP Code:
int et = TimeCurrent()+(PERIOD_M5*60)*2;
 
OrderSend(Symbol(),OP_BUYSTOP,0.10, 0,3,0,0,"0",0,et,Green); 
I need to set the expiration time to 3 min. How should the code look like if i want to that?

Tried this but doesn't work eather

PHP Code:
int expiration = TimeCurrent()+(PERIOD_M1*60)*3; 
It's not placing the limit order

Are you checking your returned error ? maybe your Broker doesn't allow you to set an expiration time or the time you are trying to set is too short ?

You must check the errors you get back when trying to place an order . . .

ehh no i don't think so.

How can i show that code? Is it something like

return();

and then use the "comment" code to show it on the screen?

My ordersend looks like this : int ticket = OrderSend(Symbol(),OP_BUYLIMIT,1.0,Bid-100*point,0,0,0,"My Expert",16384,expiration,Blue);

OrderSend returns either the ticket number or -1 if the send failed . . so

if (OrderSend(Symbol(),OP_BUYLIMIT,1.0,Bid-100*point,0,0,0,"My Expert",16384,expiration,Blue) < 0) Comment("OrderSend failed: error ", GetLastError());

Ok it says:

OrderSend failed error: 3
ERR_INVALID_TRADE_PARAMETERS 3 Invalid trade parameters.

Try a longer period, maybe 24hrs

If you look in the Toolbox of MetaEditor under help you can find all the MQL4 syntax and error messages there . .

I did a few test and it work with 15min, but not with 5min so there we have the answer. The broker doesn't allow expiration time below 5 min.

Problem solved!

Thanks for your help RaptorUK.
