Buyer vs Seller

Every option trade has two sides. One person's gain is the other's loss.

The Two Sides

Option Buyer

  • Pays the premium upfront
  • • Wants the market to move big
  • • Limited loss (only the premium)
  • • Unlimited profit potential

Option Seller

  • Receives the premium upfront
  • • Wants the market to stay calm
  • • Limited profit (only the premium)
  • • Unlimited loss potential

Call Option Premium

574

Buyer pays ₹574 → Seller receives ₹574

See It in Action

Call Option — Strike: 24500, Premium: ₹574

Where does Nifty end up?24,200

Buyer

-574

Lost 574 of ₹574 premium

Seller

+574

Keeping 574 of ₹574 premium

Market below strike

Nifty ended at 24,200, which is below the strike price of 24500. The call option expires worthless. Seller wins — they keep the full premium of ₹574. Buyer loses ₹574.

It's a Zero-Sum Game

Notice something? Buyer Profit + Seller Profit always equals zero.

Buyer (-574) + Seller (+574) = 0

Whatever the buyer gains, the seller loses, and vice versa. This is why options are called a "zero-sum game".
