Based on the time-weighted average of the index price in the last hour before the expiration, the delivery price is $19,000, then the profit/loss for him is: Face value * number of contracts / avg. opening price – face value * number of contracts / exercise price = 100 * 1,000 / 15,000 - 100 * 1,000 / 19,000 = 1.4035 BTC Example 2: User B held 1000 short options contracts ETHUSD-20230929-1600-P until the expiration date, 4:00 pm on Sep 29 (HK time).

A user longs 10 put options contract BTCUSD-200327-20000-P (A put option with an exercise price of 20,000 USD and expiration date on March 27, 2020), and wants to hold some futures contract with the same expiration date to hedge the delta risk fully. The following two tables show the information of the options contract and futures contract.

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.

Therefore, all positions are ranked in the ADL queue by leveraged P&L ratio as usual.

Auto deleveraging will be executed in the order of account and position risk degree and P&L ratio.
