Funding Rate= {clamp{Floor, {ABS\[(Long OI - Short OI) \* Funding Fee Per Hour/M % ] /  Max (LongOI, ShortOI)} ,Cap} }

#### **Parameters:**

* **Long open interest:** The total number of LONG positions on the platform.
* **Short open interest:** The total number of SHORT positions on the platform.
* **Funding Fee Per Hour:** The Funding Rate will be charged on an hourly basis. It may be adjusted based on market performance.
