Options and stock research with IV rankings, unusual volume, earnings-move history and strategy screeners; much is free, $99/mo Premium adds history.
What it is
Market Chameleon is a research site for options traders more than a trading platform. It publishes implied volatility rankings and movers, unusual option and stock volume, order flow sentiment, an open interest dashboard, 0DTE straddle pricing, and screeners for verticals, iron condors, butterflies, calendars, covered calls and naked puts. Earnings pages show historical straddle performance and how far each stock has moved around past reports, and there are dividend, pre-market and after-hours reports.
A free registered account opens a large part of the site, with market data delayed 15 minutes. Premium, the single paid plan, is $99 a month with a seven-day trial, and adds depth rather than new sections: up to three years of stock price and volatility history, ten trading days of option trades instead of the current day, earnings and dividend calendars beyond three business days, peer-group comparisons, custom stock and strategy watchlists, saved screener presets and more screener filters.
Premium also raises CSV downloads from 2 to 25 in a rolling 24 hours. Separate data feeds ($500 a month each) and historical option trade files are sold for firms that need raw data. Annual Premium pricing is not listed; the site says to contact support.
