The EA I wrote three months ago can not pass the strategy testing now, but it used working well two or three months ago!!
Try add ZeroMemory(sell).
if (condition1) { ZeroMemory(sell); sell.action = TRADE_ACTION_DEAL; sell.type = ORDER_TYPE_SELL; sell.symbol = _Symbol;We have fixed this issue, wait for next build, please.

I notice in the MQL5 reference (latest version that just updated today), there is no ORDER_FILLING_AON anymore, but even I use ORDER_FILLING_FOK, I still encounter error 4756. Please advise.
| Identifier | Description |
| ORDER_FILLING_FOK | The deal can be executed exclusively with a specified volume at the equal or better price than the order specified price. If there is no sufficient volume of offers on the order symbol, the order will not be executed. This type of filling is used in SYMBOL_TRADE_EXECUTION_INSTANT or SYMBOL_TRADE_EXECUTION_REQUEST execution modes. |
| ORDER_FILLING_IOC | An agreement to execute the deal with maximal market volume at the equal or better price than the order specified price. In this case an additional order for volume unfilled will not be placed. This type of filling is used in SYMBOL_TRADE_EXECUTION_MARKET and SYMBOL_TRADE_EXECUTION_EXCHANGE execution modes depending on the symbol settings on a trade server. |
| ORDER_FILLING_RETURN | An agreement to execute the deal with maximal market volume at the equal or better price than the order specified price. In this case an additional order for volume unfilled will be placed. This type of filling is used only for pending orders (TRADE_ACTION_PENDING). |
Hi, any comment before I give up MT5 and go back to MT4? Many thanks! I am actually new to both but would give MT5 a try first although I know it is very new.
Add this before the mrequest:
ZeroMemory(mrequest); ZeroMemory(mresult);
I've had the exact same problem as you did and it fixed it for me.
I have the same problem now.
My expert advisors were working very well. But now all of them can't pass the tester.
When I compile the file's, the following messege will shown:
'ORDER_FILLING_AON' - undeclared identifier
How can this problem be solved??
IIs this the result of a terminal update? (Version 5.00 Build 642)
(24 april 2012)
Hope that somebody can help me

Replace ORDER_FILLING_AON to ORDER_FILLING_FOK (see Order properties)
Add this before the mrequest:

Hello, I've added these 2 lines in the code but error 4756 still here (Trade request sending fail).
Could you please precise where excatly I should add the 2 lines ? The one concerning mrequest is already present. Adding both of them doesn't change anything for me. Thank you for the help I'd appreciate.
I'm running rel.5 build 842.
