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
The big players were active all day. 25 bars of outsized trades (7.8σ peak) from 00:56–23:50 UTC, adding 748 BTC of buying pressure on top of the broader buying flow.
Flow reversed midday. The first 12 hours belonged to sellers (-1,577 BTC), but buyers erased that and then some (+3,435 BTC) in the back half.
From $38,313 to $42,317 — a 10.0% range that forced both bulls and bears to respect the volatility.
A clean, flow-driven day. The 0.94 correlation between cumulative flow and price means buying pressure was the dominant force — no hidden passive flow muddying the signal.
