I use MT4 as the data provider in order to send real-time data to Amibroker as the figure below.
But once I open Amibroker, it always arises this message on window so long.
However, whether I click Hide Buttom to close it or ignore it. my Real time data from MT4 still synch to Amibroke absolutely.
How to not popup this window.
This is problem with data source. In this case MT. Nothing can be done from AmiBroker side. It just calls MT4 dde server and waits for response that apparently never arrives.
Could you also try the settings mentioned by @fxshrat in one of his previous post.
