ORDER_FILLING_FOK

My broker does not support the ORDER_FILLING_FOK order execution mode for futures market. 
The ORDER_FILLING_RETURN  or  ORDER_FILLING_IOC mode is supported.
Therefore, the strategies made for Metatrader 5 do not do the transaction when testing or auto-trade mode is enabled.
Giving an error - code 4756.
"Error description: Trade request sending filed. The order could not be completed. Error no .: 4756"
By default, when the expert is initialized, as far as I understand, the default order is FOK.

I would like to be able to form a strategy in the UK to handle this error, or at least comment on / fragment the code area, depending on the broker's settings.

By default, when the expert is initialized, as far as I understand, the "type_filling" is ORDER_FILLING_FOK.

The broker recommends using Trade.mqh for setiing ORDER_FILLING_FOK. 
For example:
#include<Trade\Trade.mqh> CTrade  trade; trade.SetTypeFilling(ORDER_FILLING_RETURN);
But the MT5 system template involves processing different modes, I would like to see this case too.
