What Syncopy does when something goes wrong
Checked against the code on 27 October 2026
Most complaints about trade copiers are not about the day everything works. They are about the moment a connection drops, an order bounces or a stop moves, and the copier does something nobody expected. This page describes what Syncopy does in each of those moments. Each case says whether it has been seen on real trades or only tested, because those are different claims and a tool that touches funded accounts should not blur them.
Your connection drops, or the machine sleeps
The session survives Seen on real trades
Syncopy renews its Tradovate session in the background, including after the machine wakes from sleep. You do not log in again because the laptop lid was closed.
Followers keep their stops Seen on real trades
When you trade with a bracket, the stop and target Syncopy places on each follower are orders at Tradovate, not something held in the app. They keep working while your machine is offline. What does not happen while you are offline: a stop you move on the leader is not mirrored until Syncopy is back, and new leader trades are not copied.
Old fills are not replayed Tested, not yet seen live
When the connection returns, fills from the last two minutes are copied as normal. Anything older is recorded but not sent as a new market order: copying a ten-minute-old entry at today's price is a different trade from the one you took. The follower is marked out of sync instead and you decide what to do. If three fills in a row are skipped this way, the app warns you; that warning has never been triggered on real trades.
One thing to know: the age of a fill is measured against your computer's clock. If that clock runs ahead, fills look old and copying stops while everything else looks healthy. The app warns when it sees this pattern.
The app closes or crashes with a trade open
Bracket orders on your followers stay at Tradovate, so the protection is still there. When Syncopy starts again, it reconnects to the follower orders it placed earlier in the same trading session, so it does not lose track of them or leave them behind. Tested, not yet seen live
The exception is an entry without a bracket. Syncopy copies it as a market order, and the follower then has no stop of its own until you place one on the leader — which Syncopy mirrors as a separate stop. If you trade without a bracket and your machine goes down, your followers are as unprotected as the leader. That is a known limitation, stated here so it is not a surprise.
A follower order is rejected
Syncopy does not retry blindly. An outright rejection — a closed market, insufficient margin, anything Tradovate refuses — is logged with the reason Tradovate gave, and the other followers carry on unaffected.
Some failures are ambiguous: a timeout or a server error, where the order may or may not have landed. Every order Syncopy places carries a unique tag, and in that case it looks the order up by that tag before doing anything else, so you do not end up with two. If it cannot tell, the log says so and asks for a manual check. Tested, not yet seen live
Behind both sits a position check. When a follower holds something different from the leader on two checks in a row, Syncopy marks it out of sync and stops copying to that account until you reconcile it. That matters most where firms prohibit opposing positions across accounts: a follower that drifts out of step is exactly how an accidental hedge happens. Tested, not yet seen live
You close part of a position
Each fill on the leader is copied in proportion to the follower's size setting, so a partial close on the leader becomes a partial close on the follower.
A closing order sent to a follower can only reduce that follower's position. It cannot carry it through zero to the other side. That guard was added after a follower did exactly that on a real trade in July; the guard itself has not yet been needed on real trades. Tested, not yet seen live
You move your stop or target
Dragging a stop or target on the leader changes the matching order on each follower in place. It is a modification, not a cancel followed by a new order, so there is no moment where the follower is without a stop. Cancelling a leader order cancels the follower's copy. Seen on real trades
A follower hits its daily loss cap
Each follower can have its own daily loss cap. It is measured from the start of the trading day at 18:00 ET, on realised profit and loss. When a follower reaches it, only that account stops receiving copies. The leader keeps running and so do the other followers. The cap resets at the next 18:00 ET, or when you reset it by hand. Seen on real trades
What it is not: it does not close a position that is already open, and it does not count open losses. Many prop firms count open losses towards their own daily limit, so treat Syncopy's cap as a second line, set below your firm's limit rather than at it.
Rollover
Contract rollover
Syncopy copies the contract the leader trades. It does not roll positions for you. When you move to the new front month on the leader, the followers move with you; a position you still hold in the expiring contract stays exactly where it is.
The daily session boundary
At 18:00 ET Tradovate clears the day's order and fill lists on its side. Syncopy records your trades as they happen, so a complete journal for a day depends on the app running during that day. If it was not, the journal can have gaps, and the app says so rather than showing an incomplete day as if it were complete.

Frequently asked questions
What happens to my trades if my internet drops?
Stops and targets that Syncopy placed on your followers are orders at Tradovate, so they keep working while your machine is offline. When the connection comes back, fills from the last two minutes are copied as normal. Older ones are not replayed as new market orders, because copying a ten-minute-old entry at today's price is a different trade; the follower is marked out of sync instead, and you decide what to do.
Does the daily loss cap close my open position?
No. When a follower's realised loss for the day reaches its cap, Syncopy stops copying new trades to that account; the leader and the other followers carry on. It does not close a position that is already open, and it counts realised losses only. Prop firm daily limits often count open losses as well, so set the cap in Syncopy below your firm's limit.
What happens if a follower order is rejected?
Syncopy does not retry it blindly. An outright rejection is logged with the reason Tradovate gave, and the other followers are unaffected. If the failure is ambiguous, such as a timeout, Syncopy first looks the order up by a unique tag to find out whether it landed, so you do not end up with two. A follower whose position no longer matches the leader is marked out of sync and receives no further copies until you reconcile it.
About this page
Syncopy is in testing and not yet available. This page describes the build running on the maker's own accounts, checked against its code on 27 October 2026. When something here changes, or something marked as tested is seen on real trades, the page is updated and the date above changes with it.
