Calendar Spread Strategy with Example
Calendar Spread Strategy (Time Spread) with Nifty Example
What is a Calendar Spread?
A Calendar Spread (also called a Time Spread) is an options strategy where you:
-
Sell a near-month option
-
Buy a far-month option
-
Same strike price
-
Same type (Call or Put)
This strategy benefits from time decay (Theta) and volatility changes.
It is mainly used when you expect the market to stay range-bound in the short term, but may move later.
Example: Nifty Call Calendar Spread
-
Nifty Current Level: 25600
-
Sell Feb 25600 CE @ 200
-
Buy March 25600 CE @ 350
Net Premium Paid
350 – 200 = 150 points (Debit Strategy)
So your maximum risk = 150 points
How This Strategy Works
-
The near-month option (Feb) decays faster.
-
The far-month option (March) decays slower.
-
If Nifty stays near 25600 till Feb expiry:
-
Feb option loses value quickly.
-
March option still holds time value.
-
You benefit from the difference.
-
Maximum Profit
✔️ Limited but attractive
✔️ Occurs if Nifty expires near the strike price (25600) in Feb expiry.
Profit depends on:
-
Time decay
-
Implied volatility
-
Distance from strike
Maximum Loss
❌ Limited to Net Premium Paid
= 150 points
Occurs if market makes a very big move before near expiry.
