Why do two copied accounts show a different profit or loss on the same trade?

Two copied accounts can close the same trade at different results because they are separate accounts that fill separately. A copier repeats the instruction into each account, it does not clone the outcome. Fill timing alone moves the result by a few ticks at most in either direction, and on a trade that finishes close to flat, a tick or two is the whole distance between an account showing green and an account showing red.

What a copier actually copies

A trade copier is software that repeats the executions you make in one of your own accounts into your other accounts. It sends an instruction. It does not send a result.

That distinction is the whole answer. Each account receiving the instruction places its own order, takes its own fill, and books its own profit or loss from that fill. Nothing reconciles them afterwards, because there is nothing to reconcile: each one is a real account that really traded.

At Phoenix Trader Funding the copier is Thor, and it works on your own accounts only, copying your own executions between them. It is not a signals service and it does not trade on your behalf.

There is a structural reason many traders run one. TFeed is Phoenix's own execution feed and carries no market data of its own, so a TFeed account is traded through a separate leader account that does have data, with the copier passing the executions across.

Fill timing, and why one tick decides the sign

A fill is the price an order actually executes at, which is not always the price showing on the screen when the order was sent. Two orders released in the same moment can sit at slightly different points in the queue and come back at slightly different prices.

Between a leader account and a copied account on TFeed, that difference runs to a few ticks at most per trade, and it runs in either direction. The copied account is sometimes the better fill, not the worse one.

A few ticks sounds far too small to explain one account showing red while the others show green, and on most trades it is. On a trade that closes near breakeven it is not. If the leader books a small win, an account filled a tick or two behind it books a small loss, and the two accounts have not disagreed about anything except where the queue put them. The closer a trade finishes to flat, the more likely its sign differs across a group.

This difference should never be described as a share of the trade. On a very small trade one tick is already a large fraction of the entire result, so expressing it that way makes an ordinary fill difference read as a serious defect. Ticks are the unit it occurs in, and ticks are the unit to measure it in.

The accounts underneath are not identical

Fill timing is the common cause. It is not the only one.

Accounts can sit on different data feeds, and the two evaluation feeds at Phoenix Trader Funding do not charge the same commission per side. Two accounts that filled at exactly the same price still net differently once the commission comes off.

Account types also differ in what they are allowed to carry. Maximum contract counts and scaling steps are set per account type and per size, so two accounts in one group are not always able to hold the same position in the first place.

Each account carries its own loss floor as well, calculated against its own balance rather than against the group. A tick of difference does not spread across the group; it stays on the account where it happened. What that floor is and what happens when an account falls through it is covered in our answer on what a breached account means and what happens next.

Reading a difference across a group

Four things can separate two accounts on one trade, and they separate them by very different amounts.

The first three are ordinary and expected. They are what running several real accounts looks like from the inside, and none of them is a fault to report.

When it is not fill timing

The mechanic above has a size, and that size is the useful test. A gap far wider than a few ticks is a different problem and deserves to be treated as one rather than explained away.

Two cases in particular are not fill timing: a copy that never executed at all, and a difference large enough to change the trade rather than just its sign. Both are worth raising with support, and the message that gets answered fastest names the accounts involved and the times of the trades, so the copy log can be read directly instead of reconstructed from a description.

One rule is worth knowing before adding accounts to a group. Copying your own trades between your own accounts is permitted, and the copier exists for exactly that. Holding one account long against another short is not permitted: cross-account hedging is prohibited on every account type, and it counts as a rule violation rather than a loss, so it can end an account that is showing a profit. The platform and feed setup is walked through in the Phoenix connection guide, and the wider rule questions are answered in the Phoenix support FAQ.

Common follow-up questions

Is a small difference between copied accounts a sign the copier failed?

No. A few ticks of difference per trade is what separate fills on separate accounts produce, in either direction. It is the expected behaviour of real accounts trading, not evidence that a copy went wrong.

Can a copied account do better than the account it copied from?

Yes. The difference runs in either direction, so a copied account can take the better fill just as easily as the worse one. Nothing in the mechanic favours the leader account over the accounts receiving the instruction.

Why should this difference never be quoted as a percentage of the trade?

Because one tick on a very small trade is already a large fraction of the whole result. Stating it that way inflates an ordinary fill difference into something that reads like a serious defect. Measure it in ticks instead.

Does a loss on one copied account affect the loss floor on the others?

No. Every account carries its own floor, calculated against its own balance rather than against the group total. A difference on one account stays on that account and does not move the limits on any other.

Am I allowed to copy trades between several of my own accounts?

Yes, copying your own executions between your own accounts is permitted and the copier is built for it. Hedging one of your accounts against another is prohibited on every account type and counts as a rule violation.

What should I send support if the gap looks much larger than a few ticks?

Name the specific accounts involved and the times of the trades in question. That lets the copy log be read directly for those executions, which settles whether a copy executed late, executed differently, or never executed.
