Friday · Minute-level BTC order flow from Binance · 1,537,349 trades
On Friday, March 31, 2023, Bitcoin ground out a +1.56% gain to $28,465. Net flow: +1,075 BTC — buyers had the edge.
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).
The big players were active all day. 22 bars of outsized trades (7.9σ peak) from 01:39–19:50 UTC, adding 584 BTC of buying pressure on top of the broader buying flow.
A clean, flow-driven day. The 0.87 correlation between cumulative flow and price means buying pressure was the dominant force — no hidden passive flow muddying the signal.

Morning and afternoon traded like two different markets. Sellers led early (-764 BTC), buyers dominated late (+1,839 BTC).
Across sessions: Asia -1.03%, Europe +2.28%, US +0.33% — with Europe doing the heavy lifting.
