Overview
clairsites builds tools for serious self-directed traders. Two products are live.
gex
What it is: a free options analytics tool for US stocks. Lives at gex.clairsites.com.
What it does: tracks options activity across the 100 most liquid US stocks and ETFs. Surfaces dealer gamma exposure (GEX), unusual flow, max pain, IV vs realized vol, sector positioning, fundamentals, insider trades, and more. About 40 product pages.
Who it is for: swing traders who think in days or weeks. The data refreshes every 15 minutes during US market hours, so it is not for second-by-second day trading.
Cost: free. A Pro tier is planned but not yet launched. When Pro ships, it will be priced well below comparable tools, with a 14-day cooling-off period and standard EU consumer protections.
cloudtrades
What it is: a stock setup detection and backtested portfolio simulation tool. Lives at trades.clairsites.com.
What it does: scans about 1,000 US stocks for specific trading setups with documented academic edge (gap-up drift, post-earnings drift, momentum, mean reversion, insider clusters). Runs the resulting picks as paper portfolios and tracks performance against the S&P 500.
Who it is for: systematic traders who want validated setups handed to them daily instead of doing the screening themselves.
How they fit together
Different products, same operator. They are not bundled and you do not need both. Some users will care only about options analytics (gex). Some will care only about stock setups (cloudtrades). Some will use both.
