Order Flow
The study of executed trades and resting liquidity — who is buying, who is selling, and at what price — as the basis for trade decisions.
What is Order Flow?
Order flow trading reads the market’s raw transaction data: executed buys and sells at each price, plus the resting liquidity waiting in the book. Where indicators summarize past price, order flow watches the auction itself — making it the dominant methodology among short-timeframe futures traders.
How Order Flow works
The toolkit: the DOM shows resting orders by price; footprint charts show executed bid/ask volume inside each candle; cumulative delta tracks net aggression across the session; volume profile maps where volume accumulated. Traders combine them to spot absorption (big passive orders eating aggression) and imbalance (one side overwhelming the other) at key levels.
Worked example
ES sells off into yesterday’s low. The footprint shows heavy selling volume printing at the level while price stops going down — absorption. Delta makes a lower low while price holds — divergence. The order-flow long against that level risks a handful of ticks below the absorption; the confirmation was visible before any candle-based signal.

| Order Flow this term | The study of executed trades and resting liquidity — who is buying, who is selling, and at what price — as the basis for trade decisions. | Strategies |
| Footprint Chart | A chart type that displays executed bid and ask volume at every price inside each candle — the X-ray view of what happened within the bar. | Strategies |
| Cumulative Delta | A running total of aggressive buying minus aggressive selling — the session-long scoreboard of which side is initiating. | Strategies |
| Depth of Market | A real-time display of all resting buy and sell limit orders at every price level — the "order book" view that shows market structure and liquidity. | Futures Mechanics |
| Volume Profile | A histogram of traded volume at each price level, revealing where the market found acceptance — and the high-volume and low-volume zones that act as future reference. | Strategies |
Why traders fail Order Flow
Reading flow without level context — absorption in the middle of nowhere means little; the same print at a session low is information. Overtrading the noise: flow updates every tick and generates constant temptation. On a funded account, order flow is a timing refinement for planned trades, not a license to trade every imbalance.
Frequently asked questions about Order Flow
What is order flow trading?
Trading decisions built on executed transactions and resting liquidity — the DOM, footprint charts, and delta — rather than indicators derived from closed candles.
What software do you need for order flow?
A platform with footprint/DOM capability and a quality data feed: Quantower, Sierra Chart, NinjaTrader with order-flow add-ons, or Bookmap are the standard choices among futures prop traders.
