When I try to perform a trading operation MetaTrader 4 shows «The trade flow is busy».
A message «The trade flow is busy» appears in case of unsuccessful attempt to perform a transaction (for instance: a client sends the second order while he hasn’t recieved the processing results of the first one), that may occur due to a temporary loss of server connection. In such case the order is put on the queue at the client’s terminal and the above mentioned message will appear if You try to perform any operation.
To clear the request queue You should restart the terminal.
