# Fee Structure

Lpotic Trade maintains a transparent fee structure for various trading activities, including opening and closing positions, stop-loss orders, and spread calculations for different asset classes.

* **Fee Details:**
  * Cryptocurrencies: Opening and closing fees of 0.1%, stop-loss fee of 0.015%, and variable spreads for different assets.
  * Forex: Tiered fee structure based on the trading pair.
  * Stocks, Indices, and Commodities: Specific fees and spreads tailored to each asset class.

**Price Impact**

* **Calculation:** Price Impact = Fixed Spread + Dynamic Spread. The dynamic spread is calculated based on open interest and new open positions relative to market depth.
* **Final Quotation:** The final price for an asset is derived by adjusting the oracle quote with the calculated spreads.

**Borrowing Fee and Rollover Interest**

* **Borrowing Fee Mechanism:** Lpotic Trade treats open trades as vault borrowers, charging borrowing fees to the dominant position (long/short) based on the open position balance. These fees are paid to the lUSDT Vault as negative PnL.
* **Rollover Interest:** Calculated based on the number of blocks from the opening to the closing of a transaction, applied to the collateral.
