Intuition Ek saanch mein badi baatTime and Sales window ek raw, unedited diary of every trade hai — every executed transaction ki chronological order mein ek printout. Jab chart batata hai ki price kya hua, tape batati hai kaise hua : kaun aggressive tha, kitna bada tha, aur buyers ya sellers abhi is waqt kaun si fight jeet rahe hain. Yeh market ki heartbeat live dekhne ke sabse kareeb ki cheez hai.
Intuition Jab charts hain toh pareshaan kyun hoon?Ek candlestick ek summary hai — 1-minute candle shayad 800 trades ko 4 numbers (O,H,L,C) mein compress kar deta hai. Woh compression information throw away kar deta hai : kya woh up-move ek bade buyer ne drive kiya, ya hazaron chhote ghabraaye hue logon ne? Kya price heavy volume par chadi (conviction) ya thin volume par (fake)? Tape granular truth rakhti hai. Hum isko aggression, absorption, aur intent detect karne ke liye padhte hain — chart par aane se pehle .
WHY it matters: Order book (Level 2) intentions dikhata hai (resting limit orders jo cancel ho sakti hain). Tape facts dikhati hai — jo trades ho chuke hain aur nahi undone ho sakte. Intentions jhooth bolti hain; executions nahi.
Definition Time and Sales (the "Tape")Ek security ke liye completed trades ki real-time, time-stamped list. Har print (row) kam se kam record karta hai:
Execution ka Time (aksar millisecond tak)
Price jis par trade execute huaSize (shares/contracts ki sankhya)Exchange/venue codeAggressor colour (green = ask par/upar execute hua → buyer ne aggress kiya; red = bid par/neeche → seller ne aggress kiya)
Definition Key vocabulary
Print / Tick ::: tape par ek executed trade line.Bid ::: sabse zyada price jo ek buyer abhi pay karne ko tayyar hai.Ask (Offer) ::: sabse kam price jo ek seller abhi accept karega.Aggressor ::: woh trader jo immediately fill hone ke liye spread cross karta hai . Jo buyers ask hit karte hain woh aggressive buyers hain; jo sellers bid hit karte hain woh aggressive sellers hain.Absorption ::: aggressive orders ek side par hit karte rehte hain lekin price nahi hilti , kyunki ek bada passive order unhe soak kar raha hai.
Intuition Colour rule yaad karne ki jagah derive karoPoochho kise trade karne ke liye price deni padi? Ek passive limit order bas baithti aur wait karti hai — woh kuch extra nahi deti. Immediately trade karne ke liye, tumhe spread cross karna padta hai. Agar tum immediately buy karte ho toh tumhe ask dena padega (seller ki price). Toh:
trade price ≥ ask ⇒ buyer was aggressor ⇒ green print trade price ≤ bid ⇒ seller was aggressor ⇒ red print bid < trade price < ask ⇒ "mid" print, ambiguous (grey)
Yeh yaad karne wali fact nahi hai — yeh spread cross karne ki definition se naturally aata hai .
Worked example Example 1 — Ek clean aggressive buyerBook: Bid 100.00 / Ask 100.05 . Tape prints:
100.05 ×500 (green), 100.05 ×800 (green), 100.10 ×1200 (green).
Green kyun? Sab ask par ya upar execute hue → buyers ne spread cross kiya. Yeh step kyun? Sirf aggressor ask pay karta hai.Delta = + 500 + 800 + 1200 = + 2500 Kyun? Sab buy-aggressive hain, toh sab positive.
Read: Buyers offers lift kar rahe hain aur price badh rahi hai (100.05 → 100.10). Genuine demand. Bias: long.
Worked example Example 2 — Absorption (yeh tricky wala hai)Book: Bid 250.00 / Ask 250.05 . Tape: 250.05 ×3000, 250.05 ×4000, 250.05 ×5000 — sab green — phir bhi ask 250.05 par rehta hai aur price advance nahi karti.
Suspicious kyun? 12,000 aggressive shares kharide aur price nahi hili. Yeh step kyun? Koi 250.05 par ek bada passive sell limit refill kar raha hai, har buyer ko absorb kar raha hai.Read: Ek bada seller strength mein distribute kar raha hai. Jab aggressive buyers exhaust ho jayenge, price often drop karti hai. Steel-manned intuition: "buying = up" — usually sach hai, lekin nahi jab ek wall absorb kar rahi ho.
Worked example Example 3 — Mixed tape par delta build karnaPrints: +300 (g), −700 (r), +200 (g), −400 (r), +900 (g).
Running delta: 300 , − 400 , − 200 , − 600 , + 300
Running value track kyun karo? Final + 300 beech mein dominate kiya. Yeh step kyun? Delta ka path (woh −600 tak gira) reveal karta hai ek seller ne hard push kiya, phir fail hua → buyers ne end mein le liya. Momentum shift.
Common mistake "Green print = price upar ja rahi hai."Sahi kyun lagta hai: green literally aggressive buying matlab hai, aur buying usually price upar dhakelta hai.
Galat kyun hai: agar koi bada passive seller absorb kare (Ex. 2), aggressive buying drop se pehle aa sakti hai. Fix: hamesha poochho "kya aggression ne price move kiya?" Heavy aggression par koi movement nahi = absorption = fade it.
Common mistake "Bada print = smart money / institution."Sahi kyun lagta hai: institutions bada size trade karte hain.
Galat kyun hai: institutions chhupaate hain kaafi chhote child orders mein slice karke (algos jaise VWAP/TWAP). Ek akela 50,000-share print aksar ek sweep ya clumsy retail block hota hai, stealth nahi. Fix: clusters aur tape ki speed padho, ek hero print nahi.
Common mistake "Mid-price prints buys count hote hain."Sahi kyun lagta hai: hum sab kuch classify karna chahte hain.
Galat kyun hai: bid aur ask ke beech ek print ka koi clear aggressor nahi hai. Fix: ise grey chhod do / exclude karo, ya tick-rule inference use karo (prior print se compare karo) — ise kabhi blindly delta mein force mat karo.
Common mistake "Delta positive ⇒ long jaana chahiye."Sahi kyun lagta hai: net buying pressure bullish lagti hai.
Fix: delta context hai. Positive delta aur stalling price = buyers trapped. Delta ko price response ke saath combine karo.
Recall Khud test karo (answers chhupaao)
Har tape print mein teen fields kaunsi zaroor honi chahiye? → Time, Price, Size (+ venue, aggressor colour).
Green print green kyun hai? → Trade ask par/upar execute hua → buyer ne immediately trade karne ke liye spread cross kiya.
Absorption ko ek line mein define karo. → Aggression ek side par flood hoti hai lekin price nahi hilti kyunki ek bada passive order ise soak kar leta hai.
Cumulative delta ka formula? → Δ = ∑ v i v i = + −
Tape Level 2 se zyada truthful kyun ho sakti hai? → Tape = executed facts ; Level 2 = cancellable intentions .
Recall Feynman: 12-saal ke bache ko explain karoSocho ek busy candy shop. Ek sign hai: sellers ₹105 chahte hain, buyers ₹100 offer karte hain. Tape ek notebook hai jahan shopkeeper har biki hui candy aur kitne mein likha karta hai. Agar bahut saare bacche seller ki ₹105 price pay karte rehte hain aur price upar creep karne lagti hai — buyers hungry hain (green). Lekin agar bacche ₹105 pay karte rehte hain aur price phir bhi nahi badhti , iska matlab hai ₹105 par candy ka ek BADA secret box hai jo kabhi khatam nahi hota — ek bada seller quietly dump kar raha hai. Jab woh box khaali hoga, prices suddenly crash kar sakti hain. Tape tumhe woh box dekhne deti hai khaali hone se pehle.
Mnemonic Colour + trap yaad rakho"Ask ke Upar, buyers Aggress karte hain (green); Bid ke Neeche, sellers Bail karte hain (red). Aggression par koi move nahi? Raaste mein ek wall hai."
Mnemonic "GAB-RB" : G reen–A sk–B uyer / R ed–B id (seller). Absorption = "push but no move."
Order Book & Level 2 Depth — intentions vs. tape ke facts.Cumulative Delta & Footprint Charts — Δ = ∑ v i Bid-Ask Spread — woh spread jo aggressor banna hai toh cross karna padta hai.Absorption & Iceberg Orders — tape par hidden passive size.Volume Profile — jahaan price par aggression accumulate hua.VWAP & TWAP Execution Algos — kyun bade orders sliced aate hain, ek print mein nahi.
Time and Sales kya hai? Har executed trade ki real-time chronological list, jisme time, price, size, venue, aur aggressor colour dikhti hai.
Print green kyun colour hota hai? Yeh ask par ya upar execute hua, matlab ek buyer ne immediately trade karne ke liye spread cross kiya (buy-aggressor).
Print red kyun colour hota hai? Yeh bid par ya neeche execute hua, matlab ek seller ne spread cross kiya (sell-aggressor).
Mid/grey print kya hota hai? Bid aur ask ke beech execute hua trade jiska koi clear aggressor nahi; naive delta se exclude kiya jaata hai.
Absorption define karo. Heavy aggressive orders ek side par hit karte rehte hain lekin price nahi hilti, kyunki ek bada passive limit order unhe soak kar leta hai.
Cumulative delta ka formula? Δ = Σ vᵢ, jahan vᵢ = +size green prints ke liye aur −size red prints ke liye.
Tape Level 2 se zyada truthful kyun hai? Tape executed trades dikhati hai (aisi facts jo undo nahi ho sakti); Level 2 resting limit orders dikhata hai (cancellable intentions).
Steel-man: 'big print = institution' galat kyun hai? Institutions bahut saare chhote algo child orders mein slice karke chhupaate hain; ek bada print aksar sweep ya clumsy block hota hai, stealth nahi.
Warning sign: price badh rahi hai lekin delta gir raha hai iska matlab? Sellers aggress kar rahe hain jab price chadh rahi hai — likely fake move / weak rally.
Trade mein 'aggressor' kaun hota hai? Woh trader jo immediately fill hone ke liye spread cross karta hai, ask pay karta hai (buy) ya bid hit karta hai (sell).
