Flow Analysis
Sustained large-player selling throughout the day. 34 bars with trade sizes 3σ+ above normal (peak: 14.6σ), spread across 00:47–23:27 UTC. The 318 BTC of whale flow reinforced the day's selling bias.
This was day 10 of consecutive net selling. Multi-day streaks reflect sustained conviction, not noise.
A clean, flow-driven day. The 0.95 correlation between cumulative flow and price means selling pressure was the dominant force — no hidden passive flow muddying the signal.
