About
Redstone is a web-based portfolio analytics and investment research product for self-directed investors, analysts and people learning portfolio theory. It provides return and risk measures for about 2,900 U.S. stocks and 1,200 ETFs, including Sharpe ratio, maximum drawdown, volatility and correlations. Users can screen securities, compare tickers, build and share portfolios, review allocations, and backtest portfolios against historical data and benchmarks. Public ticker data and comparisons are available without an account. Free and paid plans add portfolio capacity, optimization tools, private portfolios and watchlists. A free, read-only Model Context Protocol (MCP) server lets compatible AI assistants retrieve metrics, screen or compare securities, look up portfolios and run backtests. Data refreshes daily after the U.S. market close. Redstone is for informational and educational use, not investment advice.

About
TwiceOver is a web-based stock and options analysis tool for active traders. Users can analyze U.S.-listed tickers without linking an account, or connect a brokerage account in read-only mode to examine holdings. For supported positions, the service groups option legs into structures and presents breakeven, maximum profit, maximum loss and current profit or loss. Traders can define price targets, maximum-loss limits and days-to-expiration rules and see how holdings compare with them. Ticker analyses bring together fundamentals, technical levels, sector conditions, peer comparisons, news and catalysts, market commentary and macro context, with a conditional outlook across near-, mid- and longer-term horizons. TwiceOver is for research and analysis; it does not place trades. Free access includes 10 analyses per month. Core costs $49 per month, includes 200 monthly analyses, and comes with a 14-day free trial.
