  • Opening/Closing a Maker position
  • Interest rate on Idle capital

How much does it cost to open a position on Perennial?

The fees are dynamically calculated when opening a position. Its based on position's impact on skew among other factors. You will be able to see a break down of the fees on when entering a position.

Why does fee change with position size?

Perennial aims to have a perfectly balanced Skew in every market. We achieve this by using a dynamic funding rate based on this parameter (See Funding Rate).
In addition, the protocol also charges a dynamic fee based on the impact your position would have on the market skew. The further the position pushes Skew up, the higher the fee. Conversely, when a position will reduce skew the fee is reduced.
