Yeh kaise hota hai, kadam dar kadam
Shuruaat
Option ka premium ₹80 hai. Abhi ki sensitivities dekhein. Delta 0.50 hai. Underlying ke har ₹1 chalne par gamma 0.01 hai. Har calendar din theta −₹3 hai. Implied volatility ke 1 percentage point par vega ₹5 hai. Implied volatility woh utar-chadhaav hai jo bazaar ke option prices se nikalta hai. Ise percentage mein kehte hain. 4 numbers hain aur sabki unit hai. Delta ke liye har rupee ki chaal. Gamma ke liye bhi har rupee ki chaal. Theta ke liye har din. Vega ke liye har percentage point. Yahan unit number jitna hi kaam karti hai.
Aage kya hota hai
1 din guzarta hai. Underlying ₹20 badhta hai. Chaal badi hai aur sahi disha mein hai. Saath implied volatility 20% se 18% girti hai. Is girawat ke 3 sahi varnan hain. 2 percentage points ki girawat. Pehle ke mukaable 10% ki girawat. Decimal scale par 0.02 ki girawat. Har percentage point ke liye diye vega mein −2 daalenge. −10 ya −0.02 nahi.
Iska matlab — aur kya nahi
4 asar baari-baari jodein. Delta se 0.50 × 20 = +₹10. Gamma sudhaar se 0.5 × 0.01 × 20² = +₹2. Theta se −3 × 1 = −₹3. Vega se 5 × (−2) = −₹10. Kul −₹1 hai. Sahi disha mein ₹20 ki chaal ke baad bhi andaaza lagbhag ₹79 hai. Isse contract galat nahi hota. 4 sensitivities saath kaam kar rahi thi. 1 ka ulta asar disha ke asar se zyada tha. Nateeja sirf abhi ki jagah ka andaaza bhi hai. Yeh unche order aur inputs ke aapas ke asar chhodta hai. Inputs maap waali jagah se door jaayein to andaaza aur kam sahi hota hai. Us samay ka uplabdh quote yeh nahi batata.
- Andaaze ka premium (₹)
- Shuruaati premium ₹80 · 80
₹80 ke shuruaati premium par baari-baari 4 asar. Delta +₹10, gamma sudhaar +₹2, theta −₹3, vega −₹10. Underlying mein sahi disha ki ₹20 chaal ke baad kul lagbhag ₹79. Kadam 1 shuruaati premium hai. Kadam 2-5 delta, gamma, theta aur vega jodte hain. Yeh kram sirf dikhaane ke liye hai. 4 saath asar karte hain. Yeh hisaab ki misaal hai, price ki chaal nahi.
Chart ka data dekhein
| Andaaze ka kadam | Andaaze ka premium (₹) |
|---|---|
| 1 | 80 |

| 3 | 92 |
| 4 | 89 |
| 5 | 79 |
Isse kya establish nahi hota
Inputs itna chalein ki sensitivities badal jaayein to andaaza option ko sahi nahi samjhata. Gamma saaf misaal hai. Uska matlab hi hai ki delta fixed nahi hai. 4 ke saath yahi hai. aur ke paas yeh jaldi badal sakte hain. Kuch minute pehle ki reading us pal ki tasveer hai. Contract ki fixed baat nahi. Anchaaha premium kisi Greek ko galat sabit nahi karta, kyunki usne premium ki bhavishyavaani nahi ki. Sensitivity batati hai ki 1 input badalne aur baaki sab rokne par model kya karta hai. Bazaar ke session mein baaki sab ruka nahi rehta.
Kya check karein
6Vega volatility ke har 1 percentage point par diya hai ya decimal scale par?
Theta calendar dino, trading dino ya saalana model figure mein hai?
Volatility ka badlaav percentage points mein hai ya pehle ke mukaable percentage mein?
Quantity ya lot size se guna karne se pehle kya sab units ek tareeke mein hain?
Nateeje ko andaaza keh rahe hain ya milne ki umeed waala result?
Yeh abhi maapi sensitivities hain. Agla nateeja nahi batati.
Aam galtiyan
420% se 18% ki girawat ke liye −10 daalna, kyunki pehle ke mukaable 10% girawat hai. Har percentage point waale vega mein input −2 hai. Galat unit se jawaab 5 guna ho jaata hai.
Badi chaal mein delta ko fixed maanna. Gamma batata hai ki delta fixed nahi hai. Isi liye sudhaar waala hissa aata hai.
Theta ko roz seedhe katne waali fixed rakam maanna. Yeh chune samay ke tareeke par model ki sensitivity hai. Option ki umar badhne par theta bhi badalta hai.
Greeks ke hisaab ko umeed ka munafa kehna. Yeh theoretical price mein badlaav ka andaaza hai. Mila nateeja entry aur exit ke fills se aata hai.
Implied volatility 20% se 18% girti hai. Platform har 1 percentage point ke liye vega deta hai. Input kya hai?
- −2, kyunki girawat 2 percentage points hai.
- −10, kyunki pehle ke mukaable 10% girawat hai.
- −0.02
Answer dikhao
A. −2, kyunki girawat 2 percentage points hai.
Dono galat jawaab isi girawat ki sahi baat hain, par galat unit mein. 20 se 18 jaana pehle ke mukaable 10% girawat HAI. Decimal volatility scale par 0.02 bhi HAI. Dono bazaar ko galat nahi padhte. Vega kis tareeke se diya hai, use galat padhte hain. Har percentage point waale vega mein input −2 hai. Baaki 2 jawaab 5 guna bade ya 100 guna chhote nateeje dete hain. Hisaab khud chetaavni nahi deta. Isi liye number daalne se pehle unit jaanchein.
Aksar poochhe sawaal
320% se 18% ki girawat 2 percentage points hai ya 10%?
Dono baatein usi girawat ke liye sahi hain. Isi liye unit zaroori hai. Yeh 2 percentage points ki girawat hai. Pehle ke mukaable 10% girawat bhi hai. Har 1 percentage point waala vega −2 istemaal karta hai.
Kya theta roz premium se wahi rakam ghataata hai?
Nahi. Yeh chune samay ke tareeke par sensitivity hai. Calendar din, trading din ya saalana model figure ho sakta hai. Option ki umar aur underlying badalne par theta bhi badalta hai. In tareekon ko mila dene par jawaab badalta hai, bina chetaavni ke.
Kya Greeks kal ka premium batate hain?
Nahi. Har Greek batata hai ki 1 input badle aur baaki sab ruka rahe to theoretical price kya karega. Session mein kai inputs saath badalte hain. 4 mein koi nahi batata ki koi input kis disha mein chalega.
