Bhaav ke moves aapke premium ko chalane wali sirf aadhi cheez hain. Baaki aadha yeh hai ki market kitna ghabraya hua hai, aur Greek parivaar ka ek pura hissa sirf usi ghabrahat ko jawab deta hai. In dials ko aapko ginna nahi hai. Aapko inke nishaan apne P&L par pehchanne hain.
Yeh cheez important kyun hai?
Events ke aas paas vega aksar delta par bhaari pad jaata hai: aapka option girti hui ghabrahat se utna gawa sakta hai jitna sahi price move se kamata hai. Woh dard aapne Lesson 9 ki IV wali kahani mein dekha tha. Ab use apna pura dial milta hai, numbers ke saath.
Vega ke peeche doosre darje ke Greeks baithe hain: vanna, charm aur vomma. Kisi retail beginner ko inhe ginne ki zaroorat nahi hai, par professional dealers inhe din bhar hedge karte hain, aur unki hedging asal mein index ki hi kharid farokht hai. Jab NIFTY kisi shaant dopahar mein ajeeb tareeke se khiskta hai, ya event ke baad mechanical dhang se unwind hota hai, to aksar wajah yahi bina chamak wali flows hoti hain. Lesson 26 woh dealer wali kahani theek se banata hai; yeh lesson uske liye shabdawali deta hai.
Reality check
Aapko vanna kabhi ginna nahi padega. Par uske hone ka pata hona zaroori hai, kyunki jab event ke baad market "bina wajah" hilta hai, to aksar boring, mechanical wajah vanna aur charm ki hedging flows hi hoti hain.
Asli market ka example
Vega, mukhya dial. Hamara 25,000 CE ₹120 par chal raha hai aur uska vega lagbhag ₹10 per 1% IV hai. Budget se do din pehle ghabrahat badhti hai aur IV 12% se 18% par chala jaata hai. NIFTY ek point nahi hila, phir bhi premium lagbhag 6 × ₹10 = ₹60 chadh kar lagbhag ₹180 ho jaata hai. 65 ke lot par woh ₹3,900 ka fayda hai (ya extra kharcha, agar aap ab kharid rahe ho), aur woh poora ka poora sirf darr se bana hai.
Event bina kisi drama ke nikal jaata hai. IV ek hi subah mein 18% se 13% ki taraf baith jaata hai, aur wahi premium lagbhag ₹50 per unit wapas de deta hai. Jo buyers darr ke shikhar par ghuse the, unhone ₹180 diye us option ke, jo ab lagbhag ₹130 ka hai, aur market wahin ka wahin hai. Yeh poora chakkar wahi IV crush hai jise aap Lesson 19 mein theek se naapoge.
Vega time ke saath badhta bhi hai. Lagbhag square root of time ke hisaab se, hamare ATM option ka 30-din wala version lagbhag ₹21 per 1% IV ka vega leke chalta hai, weekly ke ₹10 se dugna. Monthly options jitne price ke auzaar hain, utne hi IV ke bhi.
Chhupa hua parivaar, nishaan se pehchano:
Vanna: IV badalta hai, aur aapka delta badal jaata hai. Event se pehle IV uchhalta hai aur OTM 25,200 CE ka delta lagbhag 0.25 se lagbhag 0.35 chala jaata hai, bhaav ko chhue bina. Zyada ghabrahat door ke strikes ko zyada pahunch ke andar bana deti hai, to unke delta mote ho jaate hain.
Charm: time guzarta hai, aur aapka delta badal jaata hai. Har shaant din usi OTM call ka delta neeche kheenchta hai, 0.25 se 0.23 ki taraf, aur expiry paas aane par aur tez. OTM ke delta 0 ki taraf behte hain, ITM ke 1 ki taraf ghiste hain, sirf calendar ki wajah se.
Vomma: IV badalta hai, aur aapka vega badal jaata hai. Position ki IV ke prati sensitivity khud IV ke prati sensitive hai, aur isiliye options market mein panic apne aap ko khilata rehta hai.
Yaad rakhne wali baatein
Vega: IV ke 1% badlav par premium mein kitne rupaye ka badlav. ATM strikes par sabse zyada aur expiry door hone par bada: hamare weekly ATM ke liye lagbhag ₹10, 30-din wale ke liye lagbhag ₹21.
Vanna: IV badalne par delta ka badlav (ya usi baat ko ulta kaho: spot hilne par vega ka badlav). OTM options par sabse bada, kyunki unki pahunch is baat par tiki hai ki market kitne movement ki ummeed kar raha hai.
Charm: time guzarne par delta ka badlav. Isi wajah se dealer ke desk par ek bina chhua OTM option bhi roz dobara hedge karna padta hai, aur isi wajah se aapki OTM position intezaar karte karte chup chaap sensitivity khoti rehti hai.
Vomma: IV badalne par vega ka badlav. Khareede hue options IV chadhne par vega kamate hain, jo premium ki darr wali rally aur uske baad ke crush, dono ko bada kar deta hai.
Dealers ko farak kyun padta hai: market-making desks hazaron option positions neutral hedge karke rakhte hain. Vanna aur charm un deltas ko lagatar khiskate rehte hain, jisse desks ko neutral rehne ke liye index futures kharidne bechne padte hain. Woh majboori wale trades khud NIFTY mein asli order flow hain, aur theek wahan se Lesson 26 shuru hota hai.
Picture mein dekho
Neeche wala card map parivaar ka chhupa hua hissa saamne rakhta hai. Har card us dial ka ek line ka kaam aur hamare aam 25,000 CE par uska nishaan dikhata hai. Aakhri card batata hai ki in dials ke hilne par ek hedged dealer desk ko trade karna kyun padta hai, jabki desk ka koi market view hai hi nahi.
Vega
Premium change per 1% move in IV. Peaks ATM, grows with time.
weekly ≈ ₹10 per IV point; 30-day ≈ ₹21
Vanna
Delta changes when IV changes. Biggest for OTM strikes.
IV spikes pre-event: 25,200 CE delta 0.25 → ≈0.35
Charm
Delta changes as time passes, even in a silent market.
each quiet day: OTM delta 0.25 → 0.23, then faster
Vomma
Vega itself changes when IV changes. Panic feeds panic.
IV rises: your IV-sensitivity rises with it
The dealer’s desk
Hedged desks must re-trade the index whenever these dials shift their deltas. That forced flow moves NIFTY itself.
Lessons 26 and 27 map these flows
The hidden wing of the family, with fingerprints on our usual 25,000 CE. You never compute these as a retail trader. You recognise them, and you remember the last card: hedged dealers must trade the index when these dials move, with no view at all.
Traders isko kaise use karte hain
Har event trade se pehle vega check karo. Apni position ke vega ko ek waajib IV girawat se guna karo aur use us fayde se milao jo aap move se expect kar rahe ho. Crush ka andaaza move ke andaaze se bada hai, to trade ulti bani hui hai.
Expiry jaan bujh kar vega dekh kar chuno. Hafton mein IV chadhne ki ummeed hai? Monthly ka ₹21 vega weekly se dugna kamata hai. Kal ke crush ka darr hai? Weekly ka chhota vega chhota bandhak hai.
Market ko gaali dene ki jagah nishaan pehchano. Bhaav hile bina delta khiska: vanna, IV hila. Shaant hafte mein delta beh gaya: charm. IV ke badlav par premium ne zyada react kiya: vomma. Dial ka naam le lena confusion ko jaankari bana deta hai.
Chhupe hue Greeks ko seedha trade mat karo. Retail trader ke liye yeh mausam hain, lever nahi. Inhe itna jaano ki haalat padh sako; hedging un desks par chhodo jinhe karni hi padti hai.
Doosre tools ke saath istemal
Vega + IV rank (Lesson 19). Vega batata hai per IV point kitne rupaye; IV rank batata hai ki IV kis disha mein khinchi hui hai. Ooncha rank plus long vega yaani saaf hote mausam mein mehnga chhata pakde rehna. Yeh jodi hafte ke sawaal ka jawab deti hai: premium kharidna hai ya bechna?
Expiry ke hisaab se vega + calendar spreads (Lesson 25). Weekly ka chhota vega bechna aur monthly ka bada vega kharidna hi poore calendar spread ka dhaancha hai: ek trade jo seedha usi vega-versus-time curve par bani hai jo abhi seekha.
Vega + event straddles (Lesson 23). Results se pehle straddle kharidna matlab gamma aur vega kharidna, theta dete hue: teen dials, ek trade. Yeh tabhi kamata hai jab move kiraye aur crush dono ko peet de, aur isiliye Lesson 23 breakevens par itna waqt kharch karta hai.
Vanna aur charm + dealer positioning (Lesson 26 aur 27). Poore index par vanna aur charm ki hedging dohraye jaane wale flow patterns banati hai, khaas kar events ke baad aur expiries mein jaate hue, aur Lesson 27 ke GEX jaise charts unhi ka naksha banane ke liye hain. Aaj ki shabdawali un do lessons ka entry ticket hai.
Aam galtiyan
Event se theek pehle "bada move aane wala hai" keh kar options kharidna. Jis move ki sabko ummeed hai, woh IV mein pehle se hai. Aapko us pehle se laage hue andaaze ko peetna hai, aur yeh sirf sahi hone se kahin oonchi seedhi hai.
Monthly options par vega nazarandaz karna. Traders "zyada time" ke liye monthly kharidte hain aur bhool jaate hain ki unhone dugna IV exposure bhi khareeda hai. 3 point ki IV girawat monthly ko market ke saans lene se pehle lagbhag ₹63 per unit ki padti hai.
Event ke baad premium girne ko manipulation kehna. Woh vega bilkul wahi kar raha hai jo dial kehta hai, aur calendar ke sabse andaaza laayak lamhe par.
Vanna ya charm ko seedha trade karne ki koshish. Dealer ki inventory aur kharcho ke bina yeh samjhaane wali cheezein hain, mauke nahi.
Nishaan se pehle formula ratna. Jis formula ko aap kisi P&L wali hairaani se jod na sako, woh hafta bhi nahi tikega. Pehle pehchan; maths baad mein khud chipak jaati hai.
