Calculation assumptions

Model: Black–Scholes theoretical pricing with a fixed 5.0% risk-free rate.

Settlement: BTC option premium and P&L are shown in USD per BTC contract.

Volatility: The demo uses a fixed 65% sample IV; the control applies a scenario shift.

Data: Prices are fictional sample values and are not current bid, ask, mark, or executable quotes.

Time: Days are calendar days remaining to the sample expiry; the displayed scenario is theoretical.

Fees: Fees, slippage, early exercise, and liquidation effects are not included.

Calculated results are estimates and can differ materially from exchange prices, execution values, realized P&L, and portfolio margin requirements.

How to read the default strategy

A bull call spread makes the trade-off visible.

This BTC bull call spread buys a lower-strike call and sells a higher-strike call with the same expiration. The short call helps fund the long call, which limits both the potential profit and potential loss. Move the scenario controls to examine how BTC price, implied volatility, and time remaining affect the structure.

A payoff chart shows the shape of the position; Greeks explain the local sensitivities; and the heatmap shows how those sensitivities change across price and time. The result is an analysis surface—not an order ticket.

Bitcoin options calculator FAQ

Is this Bitcoin options calculator free to use?

Yes. The public demonstration is interactive and does not require registration. An account is required only for cloud saving, current exchange data, alerts, and authenticated portfolio features.

Are the prices live?

No. This page uses a fixed, versioned sample market snapshot so the demonstration remains reliable and transparent. It does not show current executable prices.

What does a bull call spread show?

A bull call spread buys a lower-strike call and sells a higher-strike call with the same expiration. It limits both potential profit and potential loss, making the payoff easier to understand before exploring more complex structures.

What do the Greeks mean here?

Delta estimates directional sensitivity, gamma shows how delta changes with BTC, vega shows sensitivity to implied volatility, and theta estimates daily time decay. They are model estimates, not guarantees of realized behavior.
