# Fees

### Open / Close fees <a href="#fees-by-storm-trade" id="fees-by-storm-trade"></a>

Open / Close fees are charged when trading operations are performed at opening and closing a position and are deducted from the collateral.

The position size takes into account the leverage value. For example, in a USDT pair, opening a position for 100 USDT with leverage x10, a trader will pay a fee = 100 \* (10 - 1) \* opening fee, and the same for the closing fee.

### Borrow fee

The borrowing fee is an hourly fee for holding open positions that is charged only on the amount of collateral. It calculates based on selected leverage for the borrowed amount.

### Gas fee

Gas fees are charged only for deposit and withdrawal transactions. All operations with your positions are **gas-free** and executed immediately.
