What an order costs, line by line.
Every figure under Order details on the ticket, defined, with one order worked through. Some of these you pay. Others are room the Arlo holds back so a stop that fills cannot take more than is left.

COSTS YOU PAY
Opening fee
GMX charges this when your position opens. It is a percentage of the size, not of your margin, so more leverage means a bigger fee on the same margin. It comes out of your margin before the position is sized. The example uses 0.06%; GMX sets the rate for each market and the ticket shows the current one.
Execution fee
A small amount of ETH that pays GMX's automated helpers to carry out your order. It comes from the wallet's ETH, not your USDC margin. GMX sends back the part it does not use, straight after the order runs. Every order needs one, including a stop and a close.
Closing fee
GMX charges a fee again when the position closes, at about the same rate as the opening fee. Break-even and Est. PnL include it.
Funding and borrowing
While a position is open, GMX charges or pays a small hourly rate. It is not in break-even or Est. PnL, because it depends on how long you hold. The Net rate tab on the chart shows it.
ROOM HELD BACK, NOT PAID
These three lines, with the opening fee, make up Risk. Only the opening fee leaves your margin when you open. The rest is room the Arlo keeps aside in case the stop fills, and whatever the close does not use comes back to your loss room.
Loss to the stop
What you lose if the price reaches your stop and it fills exactly there: the size times the distance from entry to the stop. The stop row on the ticket shows the same loss as a share of your margin.
Close
Room held back for the cost of closing at the stop: $1 plus 0.10% of the size. Nobody takes this from your margin. When the position closes, only GMX's real closing fee is paid, and the rest of this room comes back to your loss room.
Slippage set-aside
In a fast market a stop can fill at a worse price than the one you set. The set-aside holds 0.15% of the size for that. It is not a charge. You only lose what the real fill costs, and when the position closes, any set-aside you did not use comes back to your loss room. Your stop order accepts a fill up to 0.30% past the stop price, so a fill between 0.15% and 0.30% uses room that was not set aside.
Risk
The four lines above added together. It is the most this position can take from the loss room if its stop fills, and the ticket will not open an order whose risk is more than the room left. When the position closes, the loss room counts only what you really lost; the rest is released.
EVERY OTHER TERM ON THE TICKET
Margin
The USDC you commit to this position, opening fee included. Each market takes at most $4,000 of margin across its open positions, and a new order's whole margin must also fit in the loss room left, because it opens without its stop.
Leverage
How many times the margin after fee the position is. Each market allows at most 50x, or less where GMX sets a lower limit.
Size
The value of the position. Your profit and loss move with the size, not the margin.
Entry
The market price the order is expected to fill at. The real fill can differ slightly.
Break-even
The price you need to reach to cover the opening and closing fees. Funding and borrowing are not included.
Margin after fee
Your margin minus the opening fee. Leverage applies to this figure.
From entry
How far your stop and your estimated liquidation price sit from the entry, as percentages.
Liquidation
The price at which GMX closes the position and your whole margin is gone. The ticket's figure is an estimate for the moment you open; borrowing costs move it closer the longer you hold. A stop must sit before it.
Loss room
How much the Arlo can still lose before trading stops. It is $4,000 on day one and changes as the wallet moves. Every open position holds part of it.
Room left still buys
The biggest next order the room left can admit on this market: the room left (up to the market's margin limit) as margin, times your leverage.
No stop
The top of the risk slider. No stop order is placed, your whole margin is at risk, and the loss room counts the whole margin until you close the position.
Take profit
Optional. A price at which the position closes in profit. You can type the price or a gain as a percentage of your margin.
Est. PnL
Your profit or loss at the take-profit price, after the closing fee.
Frozen stop
If the price moves past your stop by more than 0.30% before it fills, GMX holds the order instead of filling it and retries if the price comes back. The desk shows it, and you can close the position or replace the stop.
