Interactive tool
Options expiration planner
Use the planner to review call moneyness, put moneyness, intrinsic value, gross strike value, and whether the option is close enough to the strike to require extra care.
Interactive expiration planner
Check moneyness, intrinsic value, and exercise risk
Enter a stock price, call strike, put strike, premium, and contract count. The planner shows simplified expiration math and the questions to verify with your broker.
This is educational contract math only. It does not predict exercise, assignment, margin, taxes, fills, after-hours movement, broker cutoffs, or whether your firm will submit contrary instructions.
How to use the output
Treat the planner as a prompt, not a broker system. If the output says a contract is near the strike, ask whether you should close the position, submit instructions, reduce size, or avoid relying on automatic processing.
