The basic payoff
A call gives its buyer upside rights above a strike under the contract terms. A put gives downside rights below a strike. The buyer pays premium; the seller receives premium and accepts an obligation. Contract multiplier and settlement determine the actual dollar or token exposure.
A favorable price move can still produce a loss when it is too small, too late, or already reflected in implied volatility.
The Greeks are a risk dashboard
Delta estimates directional sensitivity, gamma tracks delta’s change, theta represents time decay, and vega measures sensitivity to implied volatility. These measures change as spot, time, and volatility change.
Short-premium positions can appear steady while accumulating tail risk. Long-premium positions can have defined loss but bleed time value. Scenario analysis should include several spot and volatility paths.
Liquidity and settlement
An option chain midpoint is not a guaranteed fill. Check spread and size at each leg. Confirm whether the option cash-settles, delivers a token, or creates a futures position.
