TechFlow news, Greeks.live macro researcher Adam posted on X platform stating that today's daily expiry at-the-money IV is only 35%, and yesterday's daily expiry at-the-money IV was even as low as 30%, illustrating how recently the crypto market dynamics have been entirely dominated by US trading hours.
For several weeks, weekend options IV has consistently followed this pattern. Comparing with spot price movements, we find that weekend volatility hasn't been significantly lower than weekdays—certainly not to such a large extent. We can thus conclude that traders during US trading hours show a stronger preference for betting on increased volatility.
