About Error 4756 - ERR_TRADE_SEND_FAILED

[Ha-yun]

In Documents, the error refers to "ERR_TRADE_SEND_FAILED"

That is:

"Sending negotiation request failed"

Nothing too objective or clear ..

This error can appear in places where?

Failure to communicate with the broker's corruption server? What else?

Here when it occurs to modify for the stop loss / take profit of an order .. Am I sending invalid values?

Thanks,

Alexandre
