5. What roles are included in the YFX perpetual contract trading?

The contract trading system is divided into "traders" and "liquidity providers." Any user can deposit funds to the fund pool and provide liquidity to the system. Fund pools take all the orders from perpetual contract trading and are the direct counterparty to traders.

6. How are trading pairs priced in different versions?

For VFX V1 and V2, the QIC-AMM model is used for pricing. The index price takes the weighted average prices on major exchanges and is updated every second.

V3 mainly uses Chainlink price feeds, supplemented by the latest price on major centralized exchanges.

7. What is the maximum position size?

If the fund pool is insufficient, the position size that the user can have is determined by the assets in the fund pools. The larger the fund pool, the larger the position size that the user can have. For the protocol's safety, there is a cap to the position size the user can have for each trading pair.

8. Can liquidity providers withdraw funds at any time?

The corresponding proportion of funds in the fund pool will be locked into the position margin when the trader opens a position.

TotalMakerAssets = BorrowedFund + Balance + UnPNL + Funding + Borrow Fees

Currently, the protocol can use up to 80% of the fund pool as trading margin, and the remaining 20% is used as a reserve to meet withdrawal demands from liquidity providers.

If there is insufficient liquidity, liquidity providers must wait for traders to close their positions before withdrawing funds.

9. How is the transaction fee calculated?

The transaction fee for trading is 0.08%.

There is no fee for liquidity providers to deposit funds to fund pools; the withdrawal fee is 0.1%.
