Kabhi aisa hua hai ki NIFTY bilkul waise hila jaisa aapne socha tha, aur aapka option hila hi nahi, ya ulta chal diya? Kuch aur dials the jo hile the. Sach kaho to paanch hain, aur aaj poore parivaar se mulaqat hai.
The five dials
Δ
Γ
Θ
ν
ρ
Delta · Gamma · Theta · Vega · Rho
Yeh cheez important kyun hai?
Naye option buyers ek seedha rule maan kar chalte hain: "NIFTY upar, mera call upar, lagbhag utna hi." Asliyat yeh rule baar baar todti hai, aur lagta hai market cheating kar raha hai. Kar nahi raha. Premium par ek saath kai forces kaam karti hain, aur har ek ka naam hai: Greeks - delta, gamma, theta, vega, rho.
Beginner ke taur par aapko ek bhi Greek calculate karne ki zaroorat nahi hai. Aapko bas yeh pehchanna hai ki jab P&L aapki ummeed se nahi milta, to kaun sa dial kaun si hairaani samjha raha hai. Bas itna hi. Aaj ka poora kaam yahi hai.
Reality check
Is lesson mein jaan bujh kar ek bhi formula nahi hai. Har Greek ko aage apna poora lesson milta hai (Lesson 16 se 18), tab jab aapke paas woh intuition ho jisse maths ka matlab bane, warna woh sirf yaad karne wale numbers reh jaate hain.
Asli market ka example
Wahi jaana pehchana NIFTY 25,000 CE lo, ₹120 par khareeda hua. Isi ek option ko pakde hue traders ke saath chaar alag hafton mein chaar cheezein hoti hain, aur har baar ek alag Greek saamne aata hai:
Hairaani 1: "NIFTY 40 point upar gaya par mera call hila hi nahi." NIFTY 25,000 se 25,040 chala. Premium ₹120 se sirf lagbhag ₹140 hua. Yeh Delta hai, yaani NIFTY ke move ka woh hissa jo aapke premium tak pahunchta hai, virle hi 1-for-1.
Hairaani 2: "Din bhar market flat raha aur phir bhi paisa gaya." Aap wahi 25,000 call pakde ho. NIFTY wahin band hota hai jahan khula tha, phir bhi premium ₹120 se ₹103 par aa jaata hai. Yeh Theta hai, time pakadne ka rozana kiraya, Lesson 6 wala decay, jo kuch na hone wale din bhi kaam karta hai.
Hairaani 3: "NIFTY upar gaya, aur mera call NEECHE." NIFTY 30 point chadhta hai, par anishchitta (maan lo results aane se pehle) achanak gir jaati hai, aur premium ₹120 se ₹105 ho jaata hai. Yeh Vega hai: expected volatility girne par premium itna gir sakta hai ki NIFTY ke saath aane wala fayda bhi kha jaye.
Hairaani 4: "Mera option aaj kal se zyada tez hil raha hai." Teen din bache hon to NIFTY ka 20 point ka move premium ko usse kahin zyada jhatka deta hai jitna do hafte pehle wahi move deta tha. Yeh Gamma hai, yaani Delta khud kitni tezi se badalta hai, jo expiry ke paas tez ho jaata hai.
Greek
Kis sawaal ka jawab
Hamare 25,000 CE ka example
Delta
NIFTY ke 1 point par premium kitna hila
0.5 → premium ₹0.50 per point hilta hai
Gamma
Delta khud kitni tezi se badla
+100 pts ke baad: Delta 0.50 → 0.62
Theta
Premium roz kitna pighla
Aaj lagbhag −₹17/din, kal aur tez
Vega
IV ke 1% badlav par premium kitna hila
IV +1% → premium +₹10
Rho
Interest rates ke prati sensitivity
Weekly option ke liye lagbhag zero

Per lot (×65), 0.5 ka Delta matlab NIFTY 1 point hilne par aapka option lagbhag ₹32.50 kamata ya gawata hai, aur yahi apna asli exposure samajhne ka sabse seedha tareeka hai.
Yaad rakhne wali baatein
Delta: NIFTY ke move ka woh hissa jo aapke premium mein dikhta hai. Hamare 25,000 CE ka Delta lagbhag 0.5 hai: NIFTY ke har 1 point par premium lagbhag ₹0.50 hilta hai.
Gamma: NIFTY hilne par Delta kitni tezi se badalta hai. Expiry door ho to aam taur par chhota, aur aakhri dinon mein tez. Matlab expiry paas aate aate aapke option ki NIFTY ke prati sensitivity jaldi badal sakti hai.
Theta: time value pakadne ka rozana kharcha, Lesson 6 wala decay engine. Yeh option buyers ke khilaaf aur sellers ke haq mein har din kaam karta hai, weekend samet.
Vega: expected volatility (IV, implied volatility) badalne par aapka premium kitna react karta hai. NIFTY ek jagah khada ho tab bhi, market kitna ghabraya ya shaant mehsoos kar raha hai, iska badlav premium hila sakta hai.
Rho: interest rates badalne par option kitna react karta hai. Weekly option ke liye yeh lagbhag bemaani hai; yahan ek baar mil lo aur jab zyada time wale options trade karo, tab tak isko side mein rakh do.
Picture mein dekho
Chalo phir se paanch dials dekhte hain, har Greek ka ek, hamare ₹120 wale NIFTY 25,000 CE par. Milkar yeh ek dashboard banate hain: Delta aur Gamma price ke move dekhte hain, Theta time dekhta hai, Vega volatility dekhta hai, aur weekly options mein Rho chup chaap kone mein baitha rehta hai.
Delta
Direction. How much the premium moves when NIFTY moves 1 point.
NIFTY +1 → premium +₹0.50 (delta 0.5)
Gamma
Acceleration. How fast delta itself changes as the market moves.
after a +100 pt rally, delta 0.50 → 0.62
Theta
Time rent. Value the option loses every day, even on a flat day.
today −₹17/unit; faster as expiry nears
Vega
Volatility. Premium change when the market gets more/less nervous.
IV +1% → premium +₹10
Rho
Interest rates. Barely matters for weekly options: meet it, then ignore it.
rates +0.25% → premium barely moves
The five dials, using our usual NIFTY 25,000 call @ ₹120. You do not need the maths yet. You need to know which dial explains which surprise in your P&L. Each gets its own deep-dive in Part 2.
Traders isko kaise use karte hain
Beginner stage mein aap dial ka naam lena seekhte ho, use ginna nahi:
P&L aapke price prediction se mel nahi kha raha?Delta dekho: woh 1 se kaafi door ho sakta hai, khaas kar OTM strikes mein.
Flat din par paisa gaya? Yeh Theta ka chup chaap chalta hua kaam hai.
Direction sahi tha phir bhi nuksan?Vega par shak karo: bhaav chadhne ke bawajood IV gir sakta hai.
Position pichhle hafte se kahin zyada sensitive lag rahi hai? Yeh Gamma hai, jo expiry paas aate hi jaag jaata hai.
Weekend par position pakad rahe ho? Yaad rakho Theta rukta nahi: do calendar din ka decay agle hi trading session par aa girta hai, chahe market band tha.
Rho? Mil lo, sar hila do, aage badho. Is course ke weekly trades ke liye yeh bemaani hai.
In paanchon ideas ko aage apna poora, numbers se bhara lesson milta hai (Lesson 16 se 18). Abhi ke liye jeet sirf itni hai ki baat karte waqt fluency aa jaye: "mera option hila hi nahi" sunte hi Delta ki taraf haath jaye, market ko gaali nahi.
Aam galtiyan
Yeh ummeed karna ki option ka P&L underlying ke saath seedhi line mein chalega. Lagbhag kabhi nahi chalta: Delta, Gamma aur Vega teenon us rishte ko modte hain.
Aam Greek behaviour ko "manipulation" keh dena. Flat din par paisa jaana Theta hai, koi saazish nahi. Rally mein premium girna aam taur par Vega hai, dhandhli nahi.
Weekend theta bhool jaana. Ghadi Shaniwar aur Ravivar bhi chalti hai, chahe NSE band ho. Somwar ka opening premium usko pehle se pakde hue aata hai.
Intuition se pehle Black-Scholes ka formula ratna. Har Greek ka matlab mehsoos kiye bina formula sirf yaad kiye hue numbers ban jaate hain jo turant bhool jaate hain. Pehle intuition, phir maths. Yeh course bhi isi order mein chalta hai.
