Nothing to keep awakeTrade copier
One fill. Every account you own.
A trade copier takes what one account just did and does it on the others. The whole question is what happens in the gap — how fast, at what size, and what it does when something goes wrong. This page answers that for Quanify, in specifics.
What a trade copier actually does
You trade one account. A copier watches that account and reproduces its activity on the others: same instrument, same direction, at a size you choose per account. The account being watched is the leader; the ones reproducing it are followers.
That description hides the part that matters. Copiers differ enormously in what they watch. A copier that reads a screen, or polls a position summary every few seconds, is inferring what you did. A copier that receives the broker's own execution report is being told.
- FillYour broker reports that the leader account filled. This is an event the broker pushes, not a number Quanify went looking for.
- MatchThe contract is resolved and the followers attached to that leader are collected. Every one is sized for its own account.
- SizeEach follower's whole-number multiplier is applied, or the strategy's fixed contract size if one is set.
- SendEach follower gets its own order on a direct broker connection. A leader fill that arrived in three parts sends three.
The step that takes time is the broker acknowledging the order — the same wait it charges every platform.
Sized per account, because your accounts are not the same size
The default copier behaviour — mirror the leader one for one — is wrong the moment your accounts differ. A four-lot trade that is reasonable on a personal account can breach a 50K evaluation on the same day.
Every follower in Quanify carries its own whole-number multiplier. One leader fill lands as a different number of contracts on each follower, decided before the order leaves.
The multipliers are whole numbers on purpose. Contracts are indivisible, so a 0.5× multiplier has to round, and a copier that rounds silently is sizing you wrong without telling you. If you want half, lead with half.

The five ways copying goes wrong
Copy trading does not fail creatively. It fails in a small number of specific ways, and the difference between tools is whether each one has a defined answer or a retry loop.
- The broker replays a fill
- Executions are de-duplicated for 60 seconds per account. A replay lands once. The window is keyed on the execution, never on the order, so a partial is never mistaken for a duplicate.
- A partial fill
- Every partial mirrors as a partial, keyed on the broker's execution id. A follower is never left holding a size the leader does not have.
- The engine restarts mid-session
- Fills stamped older than 30 seconds are refused rather than re-mirrored. A restart cannot replay your morning.
- A fill targets an account that is not yours
- It cannot. A group only contains accounts you have connected and enabled yourself.
- One account needs to stop
- Mute it. It stops taking fills while staying linked and configured. Unlinking to pause an account — and re-linking to resume — is how routing gets lost.
Nothing to keep running
Most trade copiers are a program on a machine. That machine has to stay awake, stay connected, and stay updated, which is why so much copier advice is really VPS advice.
Quanify holds the broker session server-side. There is nothing to install, no bridge process between you and your broker, and no desktop app whose crash you find out about from a position you did not expect. Your copies continue with your laptop shut.
No bridge
Quanify connects to each broker over its own API. No intermediate service holds your orders, and no third party sits between you and the fill.
Direct broker connectionsNothing arms itself
Every follower you add lands disabled. Configuring a copy group does not start it copying — you turn each account on deliberately, and it reports armed only once the engine confirms it.
Off is the default, everywhereAbout speed, honestly
Every copier markets itself as fast, so the number is worth breaking apart. End to end, a leader fill reaches a follower in roughly 50 to 200 milliseconds. Almost all of that is your broker: the round trip that told us about the fill, and the round trip that places the follower's order.
Quanify's own contribution — matching the fill, sizing every follower, running the risk checks and dispatching — is measured in microseconds, and it is under a tenth of a percent of that round trip.
This is the part worth understanding before you shop on latency: no copier is faster than your broker, because no copier can place an order your broker has not accepted yet. What a copier controls is whether it adds anything meaningful on top. Ours does not.
Which copier page you actually want
The mechanics above are the same everywhere. What differs is the platform you connect and the rules you are trading under.
By platform
Tradovate, NinjaTrader, TopstepX and TradingView each connect differently and each page covers its own path.

Running funded and evaluation accounts is a different problem from mirroring a signal seller, and the risk controls that matter are different too.

If you are still deciding whether to copy at all, what copy trading is and whether it is legitimate are the two pages worth reading first.
Start here if you are newCommon questions
What is a trade copier?
Software that reproduces one account's trades on other accounts. One account is designated the leader; the others are followers. When the leader fills, each follower places its own order in the same instrument and direction, at whatever size that follower is configured for.
Do I need a VPS to run a trade copier?
Not with Quanify. The broker connection is held server-side, so there is no program on your machine that has to stay awake. Copiers that are desktop applications do generally need a VPS, which is why so much copier advice is really advice about renting a server.
Can I copy trades between accounts at different brokers?
Yes, as long as both are accounts you own and both brokers are supported. The leader and the followers do not have to be on the same connection or the same platform.
Whose accounts can I copy to?
Accounts you own. Every account in the group is one you connected, and there is no configuration in which a fill reaches an account that is not yours. Copy Trader is built for the case almost every futures trader is in — a personal account, a funded account and one or two evaluations that all need to trade together.
What happens to open positions if I turn the copier off?
Nothing. Quanify never closes a position on your behalf — not on power-off, not on cancellation, not when a group is deleted. New signals stop arriving; anything already open stays at your broker, under your control.
Is there a free trade copier?
You can run the whole product against a simulated or evaluation account before paying for anything, which is the part most people actually want to test. See the pricing page for what each tier includes.
