Buy and Sell Pressure
Buy pressure is the aggregate force of participants trying to push price up — aggressive market buys plus firm resting bids; sell pressure is its mirror. Price at any instant reflects which pressure is winning. Reading pressure means reading both what executes (the trades) and what stands ready (the book).
How do you measure buy and sell pressure?
Two complementary families of measurement exist. Flow-based measures look at executed trades: taker buy versus taker sell volume, and cumulative volume delta (CVD), which keeps a running total of buy-initiated minus sell-initiated volume to show which side has been aggressing over time. Book-based measures look at resting intent: bid versus ask depth near the price, and how each side replenishes after being consumed. Neither family is sufficient alone — trades without book context miss absorption, and book snapshots without trades can be spoofed — so serious pressure analysis reads them together over a defined window.
What does rising buy pressure look like?
The textbook sequence: the share of buy-initiated volume climbs and stays elevated rather than spiking once; the ask side of the book thins as offers are lifted faster than they are replaced; bids step upward behind the price instead of retreating; and price advances hold instead of instantly retracing. Any single element can be faked or fleeting — one large buyer can print an impressive minute — so persistence across time and confirmation across both trades and book carry the information. Divergences are equally telling: price rising while buy-initiated flow fades is a rally running on thin commitment.
