Strike Price Sensitivity
Strike price sensitivity measures how the value of an option changes as the strike price moves relative to the current market price of the underlying asset. For a digital call, this sensitivity is most pronounced when the asset price is near the strike.
As the strike price increases, the probability of the option expiring in the money decreases, reducing the value of the digital call. Conversely, if the strike price is set well below the current market price, the option is deep in the money and behaves almost like a fixed-income instrument.
Traders analyze this sensitivity to determine the optimal strike price for their directional bets. In crypto markets, where price swings are large and rapid, the strike price choice is a critical decision that balances the potential payout against the probability of success.
It is a fundamental component of strategy design in derivatives trading.
