Strategy 1 — Box Spread
How it works
A box spread combines 4 option legs that lock in a guaranteed payoff of K2 − K1 at expiry — regardless of where the underlying closes. NSE index options are European (no early exercise), so the payoff is truly risk-free.
BUY
Call @ K1
₹950
− ₹950
SELL
Call @ K2
₹547
+ ₹547
BUY
Put @ K2
₹1,245
− ₹1,245
SELL
Put @ K1
₹864
+ ₹864
Net Debit = 950 − 547 + 1,245 − 864 = ₹784 / unit
K2 − K1 = 57,300 − 56,500 = ₹800 / unit
Gross Profit = (800 − 784) × 30 lots = ₹480
After charges = ₹480 − ~₹200 = ₹280 net profit
Why is the payoff guaranteed?
| Underlying at expiry | Calls pay | Puts pay | Total |
|---|---|---|---|
| Above K2 | K2 − K1 | 0 | K2 − K1 |
| Between K1 and K2 | S − K1 | K2 − S | K2 − K1 |
| Below K1 | 0 | K2 − K1 | K2 − K1 |
Only execute when net profit > ₹12 / lot after ALL costs
