Simulation Lab
Build the trade before you place it
The lessons explain each strategy with a fixed example. These hand you the inputs. Set your own strikes, premiums and expirations, choose where the stock finishes, and watch every number move. Collateral, breakeven, adjusted basis and what you actually keep.

The Wheel
Run a full cycle: sell a put, take assignment, write calls, get called away. Every stage, with the cash ledger.
BeginnerPoor Man's Covered Call
Substitute a deep in-the-money LEAPS for 100 shares and sell calls against it. See what the capital saving really costs.
AdvancedPut Credit Spread
Sell a put, buy a further one for protection. Defined risk, and a fraction of the collateral a cash-secured put needs.
IntermediateCall Credit Spread
The mirror image: sell a call, buy a higher one. The bearish side of defined-risk premium selling.
Intermediate
Every simulator prices from the same engine as the lessons, and none of them fetches live market data. You supply the quotes. They model expiration outcomes, not the path a position takes to get there.
