Trades aren't copying: the checklist

Work down the list

1. Is the engine actually copying? Read the engine strip on the Trade Desk, Accounts, Copy Rules, or Risk Management (on a phone, the Desk or Rules tab). 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. If it stopped without you (an amber Stopped, or a Plan limit message), the reason is on record.
2. Does the group have a leader and an instrument? Open Copy Rules and check the group's Leader account and Instrument, or for a quick read-only look press View rules above your positions on the Trade Desk. A group missing either one copies nothing.
3. Is the follower's row On? A paused follower shows a PAUSED tag on Copy Rules, and its Follow switch on the Trade Desk is off. Flip it back on. The group's Rules panel on the Trade Desk is the quickest place to see it: it lists every rule as On or Paused. Pausing keeps the settings, it just stops the copying. One instrument can also be paused on its own after a per-position Close, with the account's switch still On: cycle the switch and choose to resume it when the app asks. See closing a single position.
4. Is the connection enabled and up? On Accounts, the login must be Enabled. Press Test on that connection to check it. The status word beside it shows the running copier, not the login: it reads Copier stopped until you start copying, and Not in session if the copier started without it.
5. Is the instrument blocked? Check Blocked instruments on Copy Rules (the Trade Desk's Rules panel shows the list too). A blocked root never copies, in any group.
6. Did the save hit your plan cap? If a save came back with a message starting "Your plan covers … accounts in total" and ending "Upgrade your plan to add more.", the rule was never stored. The same message on Start copying means copying never started, and after a downgrade it can also be why copying stopped on its own. See plans and account limits.
7. 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.
8. 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.
9. Is the row amber? A DRIFT tag (Catching up on a card) 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.
10. 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.
