Flow Analysis
Sustained large-player buying throughout the day. 35 bars with trade sizes 3σ+ above normal (peak: 13.0σ), spread across 00:31–23:36 UTC. The 259 BTC of whale flow reinforced the day's buying bias.
Most of the action happened during US hours, which accounted for 63% of the day's net flow (487 BTC buying). The rest of the day was a footnote.
A clean, flow-driven day. The 0.86 correlation between cumulative flow and price means buying pressure was the dominant force — no hidden passive flow muddying the signal.
