That day's trend: Cautiously bullish

That day's view: BTC opened on July 21 at $65,255.51 and closed at $66,556.16, with an intraday high of $66,956.15 and a low of $65,148.75 — a 24-hour gain of +1.99%. Volume of 18,618 BTC (approximately $1.233 billion) expanded 1.99% versus the prior window. Average perpetual funding stood at +0.00504%, elevated relative to the BTC baseline but still moderate. Open Interest rose 3.02%; with price and OI moving in the same direction, the move tilts toward fresh long initiation (a) rather than pure short-covering. The Fear & Greed Index sat at 25, still in fear territory — the rally has not yet earned broad confirmation. Watch $66,956 resistance and $65,149 support. A clean breakout above the prior high on rising volume would extend the rebound; if OI keeps rising while price loses support, watch for crowded-long risk.
