BTC price (blue) and trading volume (cyan bars) per minute. Session shading: Asia (gold 00-08 UTC), Europe (green 08-14), US (red 14-00).

Flow Analysis

Sustained large-player buying throughout the day. 27 bars with trade sizes 3σ+ above normal (peak: 9.3σ), spread across 01:02–23:52 UTC. The 423 BTC of whale flow reinforced the day's buying bias.

A volatile day: 10.1% range from $56,078 to $61,844. Wide ranges like this create opportunities but also traps for directional traders.

Price followed flow faithfully (correlation: 0.98). When you see this level of alignment, it means one side is in control and the other isn't even fighting.

Across sessions: Asia +0.21%, Europe +4.48%, US +2.12% — with Europe doing the heavy lifting.
