Bitcoin order flow is the real-time stream of every trade hitting the market, each stamped with a direction, a size in USD, and which side was the aggressor. It is the causal signal behind price — not a lagging reflection of it. Reading order flow means reading intent before it prints on a chart.
Makers and takers
Every trade has two sides. The maker posts a resting limit order and waits. The taker crosses the spread with a market order that fills immediately against that resting order. The taker is the aggressor — they accepted a worse price to trade now, which is why their side reveals intent. A large market buy lifting the offer says someone wants in at the current price, not a better one.
This dashboard measures the taker side. The optional Maker view simply inverts it — every taker buy is a maker sell — useful for seeing the passive side of the same flow.
The key terms
- Taker buy volume — USD value of trades where the taker was buying (market buys).
- Taker sell volume — USD value of trades where the taker was selling (market sells).
- Net delta — taker buy minus taker sell. Positive means buyers were in control.
- CVD — Cumulative Volume Delta: the running total of net delta, i.e. the trend line of who has been in control.
Why flow leads price
Price is the equilibrium that order flow produces. When aggressive buyers consistently outpace sellers, the resting sell liquidity at each level gets consumed and price must rise to attract new sellers. The imbalance comes first; price follows. That's why the relationship between delta and price is so telling.
- Strong buy delta + rising price — buyers in control, move backed by real flow.
- Rising price + shrinking delta — buy aggression weakening; possible exhaustion.
- Heavy sell delta + stable price — large sellers being absorbed; watch for a breakdown or a reversal if absorption holds.
- Both spot and futures buying — real capital and leverage aligned; strongest bullish read.
Two markets at once
Bitcoin trades on spot (immediate settlement, real coin) and perpetual futures (leveraged, no settlement) simultaneously, with futures volume often several times spot. When the two agree the signal is strong; when they diverge, a resolution is brewing. See the Spot vs. Futures guide for the full treatment.
How to read it on the dashboard
- Start with the verdict and net delta at the top — the one-glance summary of who dominated.
- Check the Spot vs. Futures panel to see whether the two markets agree.
- Use the CVD chart for the cumulative trend, and the per-exchange panel to see which venues drive it.
Common questions
- How is order flow different from price? — Price is the outcome; order flow is the cause (the imbalance between aggressive buying and selling that moves it).
- What does 'taker' mean? — The side that crosses the spread to execute now; the aggressor. Buy flow = taker bought; sell flow = taker sold.
- Is it useful for non-professionals? — Yes. These aggregated signals used to be desk-only; here they're public and free to read.
