# Funding

Funding fees are periodic payments exchanged between traders who hold open positions.

They exist to keep prices aligned with the underlying market by balancing long and short positions. Depending on market conditions, funding fees can be positive or negative.

#### <mark style="color:$warning;">How Funding Works on HYPERPNL</mark>

All funding fees on HYPERPNL come directly from Hyperliquid.

* Funding rates are determined by Hyperliquid
* HYPERPNL does not set, modify, or control funding fees
* Funding rates are visible in the trading interface

HYPERPNL simply applies the funding mechanics of the underlying Hyperliquid markets.

For a detailed explanation of how funding rates are calculated and applied, refer to [Hyperliquid’s official documentation](https://hyperliquid.gitbook.io/hyperliquid-docs/trading/funding).
