Trades aren't copying: the checklist
You traded on the leader and a follower did nothing. Work this list top to bottom. It is ordered by how often each item turns out to be the answer.
Work down the list
- Is the engine actually copying? Read the engine strip on the Trade Desk, Accounts, Copy Rules, or Risk Management. It says one word, and the dot beside it carries the rest. Copying with a green dot is the healthy state. Copying with an amber dot means the kill switch is armed, usually because someone pressed Flatten all: the engine is up but places nothing until you press Resume copying. Stopped means nothing copies at all: press Start copying.
- Does the group have a leader and a leader instrument? Open Copy Rules. A group missing either one copies nothing.
- Is the follower's row On? A paused follower shows Paused and its Follow switch off. Flip it back on. Pausing keeps the settings, it just stops the copying.
- Is the connection enabled and up? On Accounts, the login must be Enabled. Press Test (the lightning-bolt button) to check it. The Status column shows the running copier, not the login: it reads Copier stopped until you start copying.
- Is the instrument blocked? Check Never copy these instruments on Copy Rules. A blocked root never copies, in any group.
- Did the save hit your plan cap? If a save came back with a message starting "Your plan covers … accounts total" and ending "Upgrade to add more.", the rule was never stored. See plans and account limits.
- Is the account locked? A daily-loss breach, a profit-target hit, or a manual lockout stops copying for that account while it keeps its position. Check Risk Management. See risk locks and the daily reset.
- Did order expiry write the quantity off? If you set an order expiry and a mirror didn't fill in time, it was cancelled and the missed quantity written off, deliberately never re-chased at market. It shows in Order history. See order expiry and write-offs.
- Is the row amber? Catching up means the follower is behind and the engine knows. Reconciliation corrects it on its own in a quiet moment. See when a follower doesn't match the leader.
- Read the record. On the Trade Desk, open Order history and check the Rejected and Failed tabs, then the alerts bell in the topbar. A reject names the broker's reason: margin, permissions, or session.
Quick answers
The strip says Copying but one account never follows.
That narrows it to items 3-8: a paused row, a disabled connection, a blocked instrument, a save the plan cap refused, a lock, or a write-off.
It copied yesterday. Nothing today.
Check the engine strip first: a stopped copier is the usual cause. Then check Risk Management for a lock that fired late in yesterday's session.
Do I have to rebuild my rules after fixing the cause?
No. Rules are stored settings. Fix the cause, and the next leader fill copies under the same rules.
