MarketChameleon

Stock Screener — Freemium

An options-focused screener with earnings volatility tools, unusual activity, and premarket scans for event-driven traders.

Earnings volatility screener

Overview

MarketChameleon is an options-focused stock screener built for event-driven traders who want earnings volatility tools, unusual activity data, and premarket scans with statistical depth. This MarketChameleon review is for traders who already live inside options chains. It rewards traders who understand options mechanics rather than casual browsers, and everything on the platform stays manual — it surfaces the data, but a trader still places every trade by hand.

The earnings volatility tools stand out, giving traders historical context and probability data around earnings-driven option strategies instead of a blind guess. Unusual options activity screens flag where size is trading against the norm, a useful signal for event-driven setups. A free tier covers the basics, so traders can test the screens before paying for the full data set. A mobile app and API access extend the screens past the browser too, letting traders check premarket movers from a phone or pull data into their own models.

The density that makes this useful for advanced traders makes it a lot to absorb for beginners; the option Greeks, volatility surfaces, and probability tools assume a base level of options knowledge going in. The free tier is genuinely limited, and the real value only shows up once a trader upgrades to the paid plan, so it works mainly as a preview rather than a complete toolkit on its own.

Coverage spans US stocks and options, aimed squarely at day trading around volatility and earnings events. Pricing runs free or $69/mo for full access, with a trial available either way, and the freemium structure means that free tier is a genuine product rather than a plain lead magnet. Beginners without options experience and long-term investors who don't trade around earnings events should skip this one; it's built for traders already fluent in options, not people learning the basics.
