Svmuu News: Greeks.live posted on the X platform, stating that today's Bitcoin call options trading volume reached nearly $8.5 billion, accounting for over 35%, primarily driven by position rollovers. Influenced by the Middle East situation and the U.S. stock market trends, the final week has seen significant volatility. However, the strategy of harvesting and dumping positions ahead of the major expiration date remains a high-probability trading approach. It is reported that this Friday is a quarterly expiration, with over 40% of options set to expire. Currently, the most concentrated strike price of $75,000 remains a strong resistance level.
