Institutional order flow is the idea that large participants push price in a consistent direction over time as they build and unwind positions. Because their orders are too big to fill at once, the resulting pressure shows up as a series of impulsive moves in one direction interrupted by smaller pullbacks.

How to read the flow
The simplest tell is impulse versus correction. Strong, wide-range candles in one direction followed by weak, overlapping candles against it suggest that side is in control. When buyers are the aggressor, dips are shallow and rallies are sharp; the reverse is true when sellers dominate.
Why it matters
Aligning with order flow means trading with the aggressor rather than guessing tops and bottoms. Most SMC setups are simply attempts to enter in the direction of the prevailing flow at a favourable price after liquidity has been taken.
- Impulsive candles reveal the aggressive side; corrective candles reveal the passive side.
- Shallow pullbacks in one direction hint at strong order flow.
- Order flow is inferred from price, not observed directly — treat it as a read.
- Trading against clear flow is possible but statistically harder.
Order flow is the direction of the aggressor — align with it instead of guessing reversals.
