In terms of skewness structure, BTC skew across all maturities converged to approximately -5 vol this week, while ETH showed structural divergence and increased short-term hedging demand. Meanwhile, ETH forward skew remained relatively stable, while BTC maintained a steeper downside protection demand. The largest cumulative transaction was a buy of BTC-131225-90000-P and a sell of BTC-131225-98000-C, totaling approximately 1,000 BTC with a net premium expenditure of approximately $170,000.

Users can customize the Delta/Strike contract selection, expiration date setting (T+1/T+2/T+3), sell price execution method, quantity, and optional profit-taking and stop-loss parameters. The strategy will automatically execute the opening position daily and seamlessly continue to the next period after expiration, achieving fully automated operation. This feature supports clear risk indicator display, margin estimation, expected trading path, and other auxiliary information to help users manage strategy execution more intuitively.PANews reported on December 11th that, according to Gate Research, implied volatility (IV) in the options market remained high this week, with BTC and ETH IV at 46% and 70%, respectively.
