What Is Order Flow?
Traditional technical analysis reads the past. Order flow reads the present — the actual buying and selling activity happening right now, not the price trace it leaves behind. It's how institutional traders see the market, and understanding even the basics changes how you interpret price action.
The Problem with Price Alone
A candlestick shows you where price has been. It's a trail of evidence — prices where buyers and sellers agreed. But it doesn't tell you how much business was done at each price, who was more aggressive, or where institutional orders are waiting.
Two identical-looking candles can have completely different stories beneath them. One might have heavy institutional buying at the lows (a strong bounce). The other might have thin retail buying that evaporates the moment the next wave of selling hits. The candle looks the same. The underlying dynamic is opposite.
Order flow analysis tries to look beneath the candle.
Key Order Flow Concepts
Bid & Ask
Bid = highest price a buyer will pay. Ask = lowest price a seller will accept. The spread between them is the transaction cost. Market orders hit the ask (buy) or bid (sell).
Market Orders vs. Limit Orders
Market orders are aggressive — they take what's available immediately. Limit orders are passive — they sit and wait. Aggressive orders move price; passive orders absorb it.
Absorption
When large selling hits a support level but price doesn't fall, buyers are absorbing the sell orders. This absorption is often a sign that strong hands are accumulating — a powerful bullish signal.
Liquidity Pools
Areas where many stop losses cluster (just below obvious support, just above obvious resistance). Large players sometimes push price to these zones to trigger stops and fill large orders at better prices.
Cumulative Volume Delta (CVD)
CVD is one of the most accessible order flow tools. It tracks the difference between buying volume and selling volume over time, plotted as a cumulative line on your chart.
When buyers are more aggressive (more market buys than market sells), CVD rises. When sellers are more aggressive, CVD falls. This tells you who is driving the market — the buyers or the sellers.
When price makes a higher high but CVD makes a lower high, the move up is not backed by aggressive buying — it's happening on less and less buy pressure. This bearish CVD divergence often precedes a reversal.
Order Blocks
An order block is a zone where a large participant placed a significant number of orders. The evidence: a consolidation area followed by a sharp, impulsive move away. The price range where the consolidation happened is the order block — it often acts as support/resistance when price returns to it, because the original large order may still be partially unfilled.
Order blocks are a concept from ICT (Inner Circle Trader) methodology and are widely used in modern institutional trading education. They're essentially a more granular version of support/resistance, with the theory that institutional orders created the level.
Key Takeaways
- Order flow analysis looks beneath price action — at the actual buy/sell aggression driving moves
- Market orders are aggressive (move price); limit orders are passive (absorb price)
- Absorption at support = strong hands buying the selling = bullish signal
- CVD tracks cumulative buying vs. selling aggression — divergence from price signals weakening moves
- Liquidity pools form where stops cluster — large players sometimes sweep them before reversing
- Order blocks = zones of institutional order placement that can act as future S/R
