About MarketWrench

Options, explained. Free tools and plain-English guides for learning how options strategies work.

What we do

MarketWrench offers free options calculators and strategy guides that break down how common trades like covered calls, cash-secured puts, and spreads work, including their payoff, breakeven, and risks.

Video explainers

Each strategy also gets a walkthrough video on our YouTube channel, with worked examples and a link to the matching calculator.
