Taker Flow — Buy vs Sell Pressure
Also known as: Taker Buy/Sell Ratio, Aggressor Flow, Market Buy vs Sell
Net aggressive buying vs selling from market takers — who is willing to pay the spread right now, longs or shorts.
What Taker Flow measures
Every trade on a crypto exchange has two sides: a maker (the resting limit order) and a taker (the order that crosses the book and gets filled immediately). Makers show where people might want to trade; takers show who is actually paying to get in or out right now.
Taker Flow compares the two:
- Taker Buy Volume — volume of market orders that hit the ask
- Taker Sell Volume — volume of market orders that hit the bid
- Ratio above 1 = buyers in control, below 1 = sellers in control
On Exum the Taker Flow subchart plots the ratio centered around zero, with green bars for net aggressive buying and red for net aggressive selling.
How to read it
| Pattern | Interpretation |
|---|---|
| Sustained green bars + rising price | Healthy trend, real demand |
| Sustained green bars + flat price | Buyers being absorbed — likely distribution into rally |
| Sustained red bars + falling price | Real selling, trend has fuel |
| Sustained red bars + flat price | Sellers being absorbed — likely accumulation into dip |
| Spike in red during rally | Short-term exhaustion — watch for pullback |
Where the data comes from
Taker data comes from perpetual futures exchanges (Binance, Bybit, OKX). Spot exchanges rarely publish a comparable stream, which is why Taker Flow is technically a derivatives signal — but it proxies spot demand extremely well because most price discovery happens on perps.
Taker Flow vs other order-flow tools
- Funding Rate — tells you whether longs or shorts are paying to keep positions open. Slow.
- Open Interest — tells you how much money is currently at risk. Medium.
- Taker Flow — tells you who is pressing the button right now. Fast.
Combine them for a full picture: rising OI + positive funding + positive taker flow = leveraged long frenzy, often near a top.
