err_requote problem - any help will do

ERR_REQUOTE

138

The requested price has become out of date or bid and ask prices have been mixed up. The data can be refreshed without any delay using the RefreshRates function and make a retry. If the error does not disappear, all attempts to trade must be stopped, the program logic must be changed.

errors list

Hi, Thank you for replaying, I read the error description and used the refreshrates function, still i get the same error, any other suggestions?

Thanks,

Meir.

change to

ticket = OrderSend ( Symbol(), OP_BUY, Lots,Ask , Slippage, dBuyStopLoss, dBuyTakeProfit, NULL, 0, 0, Green ) ;
ticket = OrderSend ( Symbol(), OP_SELL, Lots, Bid, Slippage, dSellStopLoss, dSellTakeProfit, NULL, 0, 0, Blue ) ;

PRICE_CLOSE is wrong

edit: I do not see where you define Slippage

& one more thing maybe u should send the order without SL & TP & use OrderModify() after OrderSend()

Thank you very much for your help, I've changed the priceclose to ask & bid and it worked.

I do not understand why do you think i should use ordermodify() instead of SL&TP? whats the logic after that?

thats my first code in MQL.

Thanks you again,

Meir.

There are many brokers that you can not send the SL TP with OrderSend()

O.K great thank you for the info, will you please help and show me how it should be written [ ticket = OrderSend ( Symbol(), OP_SELL, Lots, Bid, Slippage, dSellStopLoss, dSellTakeProfit, NULL, 0, 0, Blue ) ; ]
with the ordermodify(), I mean how do I open the order ?

Try something like this:

ticket = OrderSend ( Symbol(), OP_BUY, Lots,Ask , Slippage, dBuyStopLoss, dBuyTakeProfit, NULL, 0, 0, Green ) ;
err = GetLastError();
if(err==ERR_INVALID_STOPS)
   {
   Print("This broker appears to use a bridge, retrying order send request");
   RefreshRates();
   ticket = OrderSend ( Symbol(), OP_BUY, Lots,Ask , Slippage, 0, 0, NULL, 0, 0, Green ) ;
   if(ticket!=-1)
      {
      OrderSelect(ticket,SELECT_BY_TICKET,MODE_TRADES);
      OrderModify(ticket, OrderOpenPrice(), dBuyStopLoss, dBuyTakeProfit, 0);
      }
   }

You'll need to insert the usual bevy of error traps and checks of course.

Thank you Phillip for your answare, will you take a look at the code I write and see if you can see something wrong with it?

it do not genrte error but allso it do not create any orders, so I dont know if its working,

if you run t on the 12/10/2010 around 15:00 it should generate an order,

Thank you, any help will do.

use some Print() or Alert() to find out your problem
