The copier tells you whether it would copy the next trade — before there is one — instead of leaving you to find out from a missing fill. Each blocker names what is wrong and what fixes it.
Not connected
The broker session is down on the leader or that follower.
Routing disabled
Order routing for that broker is switched off on the server. Nothing you can change from the page.
Not armed yet
The copier has not completed its first comparison of leader and follower positions, so it does not yet know what "changed" means.
Group paused
The group's own switch is off.
Manual fills excluded
The leader's trade was taken by hand and hand-taken trades are not being copied.
Follower disabled
That one follower is switched off.
Blind
The broker has stopped answering. Copying continues for a short grace period and then stops.
Readiness refreshes about every 20 seconds rather than streaming. A change you just made can take a moment to show — that delay is in the display, not in the copying.
