The one-line definition

Traditional volume bar — neeche, time ke base par. "Aaj kitna kaam hua." Volume profile alag hai — vertical histogram, price ke base par. "Har price level pe total kitna kaam hua, given window mein." Same data, alag axis — alag truth dikhti hai.

Indian intraday traders ke beech yeh popular hai (TradingView default feature), par daily-chart pe bhi useful insight deta hai — kis price pe market ne "rest" liya, kahaan tezi se nikla.

The 5 key terms

  • POC (Point of Control) — woh single price level jahaan sabse zyada volume traded hua window mein. "Market ka centre of gravity."
  • VAH (Value Area High) — upper boundary of "value area" — woh zone jisme 70% (default) total volume hua.
  • VAL (Value Area Low) — lower boundary, same logic.
  • HVN (High Volume Node) — koi bhi price level jahaan local peak hai histogram mein. POC sabse bada HVN hai, par chhote HVNs bhi important hain.
  • LVN (Low Volume Node) — uska opposite — gaps in the profile. Price aksar in zones se tezi se guzarti hai.

Why HVN behaves like support/resistance

Crowd psychology: jahaan zyada log trade kiye, woh price emotionally important hai. Wahaan log ek dusre ke against position ban'aate hain — buyers + sellers dono engaged. Price waapas us level pe aati hai toh decision-makers dobara react karte hain — yeh natural zone of support/resistance ban jaata hai.

Tietiy ka SR zones producer pivot-clustering use karta hai, par advanced traders volume-profile HVNs ko complementary signal ke roop mein dekhte hain. Dono usually converge — pivot cluster aur HVN aksar same price-band pe milte hain.

LVN gaps — fast-move zones

LVN ka matlab — us price pe market ruka nahi, tezi se nikal gaya. Iska implication — agar price wapas us LVN tak aati hai, woh usually wahaan ruk'ti nahi — same speed se cross karti hai.

Trading mein iska use — LVN ko intermediate target nahi banao. Stops ko HVN/POC ke just beyond rakho, LVN beyond nahi.

Two profile modes — session vs composite

  • Session profile — single day ya single session ka profile. Intraday ke liye standard.
  • Composite profile — multiple sessions merged. Daily charts pe useful — last 20 sessions, 60 sessions, ya pichli swing-cycle ka composite.
  • Tietiy v1 mein volume profile nahi dikhata directly chart pe — kyunki daily OHLCV se volume profile estimate karna intraday data ke bina rough hota hai. Yeh future enhancement hai (intraday data feed-integration ke saath).

What volume profile does NOT tell you

  • Buy or sell. Volume aggregate hai — kitne buyers vs sellers, woh OHLCV se nikalna possible nahi (sirf order-book / tick data se).
  • Future POC. Naye trend mein new POC develop hota hai. Pichla POC reference hai, target nahi.
  • Time component. Profile time-agnostic hai — "kab" yeh volume hua, woh information lost ho jaati hai. Recent vs old volume same weight hota hai (jab tak weighted profile na use karo).

60-second reading checklist

  • POC kahaan hai? — yeh "fair value" hai window ke andar.
  • Price abhi VAH ke upar, VAL ke neeche, ya value area ke andar?
  • Visible HVNs — yeh next support/resistance zones hain.
  • Visible LVNs — yeh "skip zones" hain, target nahi.
  • Profile shape — symmetric (balance), skewed (trending), or bimodal (transitional).

Practical note. Volume profile ek complementary tool hai — pivot-based SR ke saath cross-check ke liye useful. Sirf volume profile pe trade decision lena risky hai, kyunki yeh time-agnostic hai aur regime context include nahi karta. Tietiy approach — pivot SR primary, volume profile secondary confirmation jab data available ho.
