OptionsKing

OptionsKing is a free options learning and paper trading app for iPhone, iPad, Android and the web. Learn through 107 lessons and quizzes, practice with virtual cash, and screen covered calls, cash-secured puts and defined-risk spreads.

Each ticker shows its best idea per strategy, ordered by a confidence score from 0 to 100. Use ROI and other filters to narrow the scan. There is no minimum score, and a score is not a probability of profit. Record your paper trade prediction, review what happened and explore a different stock price.

OptionsKing never connects to your brokerage and never places a trade — you place real orders through your own broker. Current trading mode is Paper. Market quotes are delayed by roughly 15 minutes.

You sign in with Google (or an email address and password) to save your watchlist, trades, and settings to your account and keep them in sync across the web app, iPhone, and Android. From your Google account we request only your name, email address, and profile picture — used to identify your account and show who is signed in. We never read your Gmail, Drive, contacts, or calendar, we never connect to your brokerage, and we never sell your data.

Explore the options learning app, the paper trading simulator, or watch the app tour. Free calculators, no sign-in required: covered call, cash-secured put, wheel strategy, payoff diagram, Black-Scholes and the Greeks, and seven more. They run the same math as the app.
