Trading Fees Taker fee = K1 × C × (P × (1 − P))² Maker fee = K2 × C × (P × (1 − P))² Settlement Fee Winning side: Use the Taker formula with P = 0.01 to calculate the settlement fee (approximately 0.01%) Losing side: No settlement fee is chargedAPI Integration & AI Agent Integration Supported account modes: Futures mode, Multi-currency mode, and Portfolio mode. Spot mode is not supported. Position mode: API access only supports Isolated margin mode.

In the above case, we could calculate a polynomial p(x) from I(x). When we use an extension_factor of 8, we will calculate another 32(8-1)* points on p(x). Since two different polynomials with D degree will share at most D points, an example polynomial pair with a valid polynomial (which satisfies the above constraints) and a fake polynomial with D degree (which does not satisfy the above constraints) will share at most D points.
