Why this page quotes no numbers
Fee schedules change, and a guide that prints one becomes quietly wrong the day it does. What does not change is the structure of the costs — what you pay, to whom, and which parts of a setup multiply them. That structure is what you need in order to compare anything; the live numbers are one click away on Phemex’s own fee page.
The costs that exist, named
- Trading fees, on every copied order. Each entry and each exit is an ordinary exchange order, charged at Phemex’s regular maker or taker rate. Copying does not discount them and does not inflate them.
- Funding, on every perpetual position held. Perpetual contracts exchange periodic funding payments between longs and shorts. Funding is charged on notional value — so a position’s leverage multiplies its funding bill relative to the margin behind it.
- Spread and slippage, on every fill. The gap between the price you saw and the price you got. Invisible on any fee schedule, real on every trade, and largest in fast markets — which is disproportionately when copied trades fire.
- The profit share — on the native path only. In exchange-built copy trading, the lead trader is typically paid a percentage of their copiers’ profits. Following a trader through CopyFi’s rules layer instead does not add a cut of your gains: CopyFi is free for a limited time, and its model is not a share of your profit.
The cost people miss: the trader’s pace is a fee setting
Two traders with identical returns can hand their copiers very different bills. One trades four times a week; the other, forty times a day. The second generates ten times the fee events and lives on taker fills. Average trade frequency and duration are printed on every trader’s stats — read them as a cost forecast, not just a style note, the way the selection guide reads the rest of the page. Inherited leverage works the same way: it silently scales the funding bill, which is one more reason a leverage ceiling is a cost control as much as a risk control.
Watching the costs before they are real
The cheapest fee education available is a testnet session: run the exact setup on paper money and watch what fees and funding do to a position over days, not in theory. If the costs eat the edge on paper, they will eat it live — and you will have learned it for free. Costs are also one of the five levers in risk management for copy trading, and one of the seven gaps in why copy traders lose money.
Common questions
Does CopyFi take a share of my profits?
No. CopyFi’s model is not a percentage of your gains — unlike exchange-native copy trading, where the lead trader is typically paid a share of what their copiers make. CopyFi is currently free for a limited time, and the first 100 users keep exclusive early-access features.
Do I pay Phemex more because the trades are copied?
No. Orders placed through your API key are ordinary orders — Phemex charges its regular trading fees, the same schedule as if you had clicked them yourself. Copying changes who decides the trades, not what the exchange charges for them.
Are testnet trades free?
Yes, in the way that matters: the testnet runs on paper balances, so its fees are paper too. Nothing you do there costs real money — which is why it is the right place to watch how fees and funding actually accumulate in a live session before real funds are involved.
Where do I find the current fee numbers?
On Phemex directly — the fee schedule for trading fees, and each contract’s page for its funding rate. Any specific number printed on a page like this one would eventually be wrong; the live source is the only one worth reading.
Trading involves substantial risk of loss, and fees and funding reduce results whether a strategy wins or loses. Fee schedules are set by Phemex and can change at any time — the live schedule is authoritative. Past performance does not guarantee future results, and CopyFi makes no investment recommendations — see the risk disclosure.
