Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it. Risk warning
Educational only, not financial advice; trading involves risk.
A model, not a market price
Black-Scholes prices an option from five numbers. The one nobody knows is volatility: the market's guess is the implied volatility in the option chain. If the value here is far from the price on screen, the market is using a different volatility. The model assumes no dividends and no early exercise, so treat it as a fair-value check, not a quote.
For the result at expiry of an option you hold, use the options profit calculator; for the usual range of the share, the expected move calculator.
Not advice. Arithmetic on the numbers you type; real option prices include spreads, dividends and early exercise.
