Sunday · Minute-level BTC order flow from Binance · 1,691,871 trades
June 20, 2021: Bitcoin ground out a +0.33% gain. The 1,490 BTC of net selling flow at $35,600 told a clear story — sellers were in charge.
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).
Large-player activity detected: 23 bars with trade sizes 3σ+ above normal (peak: 5.6σ) between 00:13–22:59 UTC. Whale flow netted 15 BTC of buying.
This was day 7 of consecutive net selling. Multi-day streaks reflect sustained conviction, not noise.
Cumulative buying pressure (purple, left axis) vs cumulative price return (yellow, right axis). When these diverge, flow and price are telling different stories.
Most of the action happened during Europe hours, which accounted for 73% of the day's net flow (2,382 BTC selling). The rest of the day was a footnote.
A tale of two halves — sellers pushed 2,333 BTC through the morning, then buyers flipped the script with 843 BTC in the afternoon.
Breaking it down by session: Asia +0.43%, Europe -4.86%, US +4.99%. US stood out.
