A maker fee is paid by the order that waited in the book, and a taker fee by the order that traded with it at once. On Cryptathon they are 0.02% and 0.05% of the position size, not of your margin. On a 2,000 USDT position that is 0.40 USDT as the maker or 1 USDT as the taker.

Who is the maker and who is the taker?
Every trade has two sides. The order that waited in the book is the maker: it made a price that others can trade at. The order that came in and traded with it is the taker.
On Cryptathon the maker fee is 0.02% and the taker fee is 0.05%. Both are a share of the position size of the trade, not of your margin. So more leverage on the same margin means a bigger fee.
One trade, two fees
You open a position with 200 USDT of margin at 10x. What is the fee if your order is the maker, and if it is the taker?
- 1Find the position sizeFees are charged on this, not on the margin.200 × 10 = 2,000 USDT
- 2Work out the maker feeFor an order that waited in the book.2,000 × 0.02% = 0.40 USDT
- 3Work out the taker feeFor an order that traded at once.2,000 × 0.05% = 1 USDT
- 4Compare themThe taker pays 2.5 times as much.1 ÷ 0.40 = 2.5
Answer0.40 USDT as the maker, 1 USDT as the taker.

What does a round trip cost?
To open a position is one trade, and to close it is another. You pay a fee each time. Together they make a round trip.
The close fee uses the position size at the close price. When the price has moved, the close fee is a little different from the open fee. On Cryptathon fees come from your free balance, on top of the margin.
A full round trip
You open a 2,000 USDT BTC long with a limit order. BTC rises 5%, and you close with a market order. What are the fees, and what is your profit after them?
- 1Fee to openThe limit order waited in the book, so it was the maker.2,000 × 0.02% = 0.40 USDT
- 2Size at the closeThe position is worth 5% more now.2,000 + 2,000 × 5% = 2,100 USDT
- 3Fee to closeThe market order took from the book, so it was the taker.2,100 × 0.05% = 1.05 USDT
- 4Add the two feesPaid from your free balance, on top of the margin.0.40 + 1.05 = 1.45 USDT
- 5Take them from the profitThe profit before fees is 100 USDT.2,000 × 5% − 1.45 = 98.55 USDT
Answer1.45 USDT in fees, so your profit after fees is 98.55 USDT.

Why is a limit order a maker?
A maker adds an order to the book. A taker removes one. On Cryptathon a limit order waits in the book until it fills or you cancel it, and it never trades at once (post-only). So when a limit order fills, it was always the order that waited, and it pays the maker fee. A market order always takes, so it pays the taker fee.
Take-profit and stop-loss exits work like this on Cryptathon: each exit is a reduce-only stop-market order that fires when the mark price reaches your level. A stop-market order trades like a market order when it fires, so it pays the taker fee.
Fees also set how far the price must move before a trade makes money. That distance is the break-even move.
How far must BTC rise to pay the fees?
You open and later close a 2,000 USDT BTC long. About how far must BTC rise to pay the fees, with market orders both ways, and with limit orders both ways?
- 1Taker fees for the round tripMarket orders both ways.2,000 × 0.05% × 2 = 2 USDT
- 2Put them as a share of the positionThe price must rise about this much to pay them.2 ÷ 2,000 = 0.1%
- 3Maker fees for the round tripLimit orders both ways.2,000 × 0.02% × 2 = 0.80 USDT
- 4Put them as a share of the positionLess than half the taker break-even.0.80 ÷ 2,000 = 0.04%
AnswerAbout 0.1% with market orders and about 0.04% with limit orders. The close fee grows a little as the price rises, so treat these as rules of thumb.
Common questions
Do you pay fees on a losing trade?
Yes. The fee is a share of the position size, not of your profit, so a trade pays it whether it wins or loses. Open and close a 1,000 USDT position with market orders and you pay 0.50 USDT each way, 1 USDT in total. If the trade loses 10 USDT, your result is an 11 USDT loss after fees.
How much does leverage add to the fees?
Fees grow with leverage, because the fee uses the position size. With 100 USDT of margin at 1x, the position is 100 USDT and the taker fee is 0.05 USDT each way. At 50x the position is 5,000 USDT and the taker fee is 2.50 USDT each way. A taker round trip then costs 5 USDT, which is 5% of your margin.
Does a liquidation pay a trading fee?
On Cryptathon there is no trading fee on the liquidation close. A liquidation still costs you: a 0.5% liquidation penalty is paid to the insurance fund. Every other close pays the normal trading fee. A close by hand with a market order pays the taker fee, and a take-profit or stop-loss pays the taker fee, because the exit trades as a market order.
