Hi,

lately I experienced weird behavior with my MetaTrader and ODL. My logs show entries like these:

07:48:29 'xxxxx': request 1.00 EURUSD
07:48:29 'xxxxx': request was accepted by server
07:48:29 'xxxxx': answer 1.00 EURUSD 1.4916 / 1.4918
07:48:32 'xxxxx': close order #1914045 buy 1.00 EURUSD at 1.4881 sl: 1.4870 tp: 0.0000 at price 1.4916
07:48:33 'xxxxx': order #1914045 buy 1.00 EURUSD closing at 1.4916 failed [Invalid parameters]
07:49:26 'xxxxx': modify order #1914045 buy 1.00 EURUSD at 1.4881 sl: 1.4870 tp: 0.0000 -> sl: 1.4906 tp: 1.4925
07:49:26 'xxxxx': request was accepted by server
07:49:26 'xxxxx': request in process
07:49:26 'xxxxx': order #1914045 buy 1.00 EURUSD at 1.4881 was modified -> sl: 1.4906 tp: 1.4925
of course 'xxxxx' is not what it said, it's censored. This is a coherent snippet, nothing is cut out within the time from 07:48:29 and 07:49:26.

1) Obviously, there was some quote request which I've never seen before. What is that? Is it about requoting?
2) OrderClose() failed with Err 3: ERR_INVALID_TRADE_PARAMETERS, what can be the reason? The price, the lot size seem to be correct. I suppose a wrong ticketNo. could be there reason, too. However, from the next entry we can tell that the ticketNo. seems to be OK since the modify-order with the exact same ticketNo went through! What do you think can be the reason for this OrderClose() failure? If you specify a wrong price as OrderClosePrice in OrderClose(), does that produce an error 3?

As you can tell I am pretty lost, I appreciate any help.
 

Ask question your broker.

It seems your broker switch execution mode on fly from request execution to instant execution and vice versa
