Strike Price
The Strike Price is the fixed price at which an option can be exercised — the reference level for whether it is in or out of the money.
What Strike Price Means
The Strike Price (or exercise price) is the predetermined price at which the holder of an option can buy (call) or sell (put) the underlying. It is fixed at the time the option is listed and never changes. The strike is the anchor against which everything else is measured — moneyness, intrinsic value, and payoff all reference it.
Exchanges list a ladder of strikes around the current spot price at regular intervals, giving traders a range of risk-reward choices.
How Strike Selection Works
Choosing a strike is choosing a risk profile. ITM strikes cost more but track the underlying closely; ATM strikes carry maximum time value and Gamma; OTM strikes are cheap, low-probability bets. Spread strategies combine multiple strikes — for example a bull call spread buys a lower strike and sells a higher one to cap cost and reward.
