📖 Beginner-Friendly Explanation
STEP 1
Core Concept & Meaning
Trading Volume and Order Flow represent the underlying monetary engine driving asset price movements.
STEP 2
Why It Matters & Mechanism
- Trading Volume: The total number of shares transacted over a set timeframe. Breakouts occurring on thin volume are prone to failure, whereas high-volume breakouts validate strong trend commitment.
- Institutional Order Flow: Tracking net buying/selling activities across foreign institutions and domestic funds. Synchronized buying by foreign and institutional entities generates sustained momentum.

Practical Investment Tips & Pitfalls
As the famous market axiom states, 'Price is the shadow of volume'—making volume validation mandatory for technical entries.
📊 Formula for determining trading volume and stock price breakout
Real breakthrough = stock price breaking through to the highest point + trading volume (300% of the usual 20-day average + massive eruption)
▶ Rise due to insufficient trading volume ➔ Beware of bull trap and profit taking
▶ Fall accompanied by trading volume ➔ Mass selling and sell-off (Bearish Breakdown)
⚖️ Key Comparison at a Glance
| Category | Large trading volume + stock price rise | Small trading volume + stock price rise | Large trading volume + stock price crash |
|---|---|---|---|
| Supply and demand status | Strong acquisition and breakthrough by foreigners/institutions | Small-scale transactions focused on individuals (wait-and-see mentality) | Large-scale stop loss and selling by institutions/foreigners |
| Reliability | Very high (confirmed rising trend) | Low (high chance of cheating whipsaw) | Risk (trend entering downward trend) |
| Trading response | Active trend following buy | Short-term profit taking and wait-and-see | Immediate stop loss and reduction |
📌 Practical Market & Real-World Example
As foreign investors injected 100 billion KRW in net buying, volume expanded to 5x its average, pushing the stock to its daily upper limit.
