Where SMC and Wyckoff infer institutional activity from the chart, order flow reads the actual transactions — the closest thing to seeing the market's cards.
Auction Market Theory frames the market as a continuous two-way auction seeking value. The tools:
- Volume / market profile — where has the most volume traded (the POC, value-area high/low)? Price tends to react at these references: fade high-volume nodes, move fast through low-volume gaps.
- Footprint & delta — inside each candle, who was aggressive (market buyers vs. sellers)? Absorption (a big passive order soaking up aggression) and delta divergence (price makes a new high, aggressive buying doesn't) are powerful turn signals.
- DOM & tape — the live order book and time-and-sales: resting liquidity, icebergs, the speed of the flow.
Who it suits. Futures scalpers and traders who want confirmation from real orders, not just chart shapes. It demands specialized tools (a footprint chart, a DOM) and screen time. But if you want to see absorption happen rather than guess an order block, this is the deepest lens there is.
