Taker Buy/Sell Ratio
The taker buy/sell ratio compares aggressive buying with aggressive selling: the volume of trades initiated by buyers (takers lifting the ask) divided by the volume initiated by sellers (takers hitting the bid). It measures which side is impatient enough to cross the spread — a direct read on directional urgency.
How is the taker buy/sell ratio calculated?
Every executed trade has a passive side (the resting order) and an aggressive side (the taker who crossed the spread). Exchanges record which side aggressed: in Binance market data each trade carries a flag for whether the buyer was the maker, and candlestick data includes taker-buy volume as a field. Summing taker-buy volume and taker-sell volume over a window and dividing gives the ratio: above 1 means aggressive buying dominated the window, below 1 means aggressive selling did. Like all flow metrics it is window-sensitive — a ratio over one minute and one day describe different phenomena.
What does the taker buy/sell ratio tell you?
It separates intensity from direction. Total volume says the market is busy; the taker ratio says who is demanding immediacy. A rising ratio during a price advance indicates buyers chasing — willing to pay the spread to get in now — which is characteristic of momentum igniting. A high ratio while price goes nowhere is equally informative in the opposite way: aggressive buying is being absorbed by passive sellers. The metric's limits: a single large taker can dominate a short window on a thin pair, and the ratio says nothing about why anyone is trading — so it is read as one input alongside price behaviour and book state, not alone.
Buy-side flow measures such as taker-buy behaviour are part of what the VolumeCatcher scanner tracks in real time from Binance public market streams.
