Volaren.

Volaren gives individual investors the research workflow that professional analysts use. A person describes a strategy in plain English and the service builds and backtests it against company filings and market data, showing the source behind every figure. The dashboard covers stocks, ETFs, options, commodities, crypto, rates and currencies, and a screener filters on fundamentals such as free cash flow yield and debt to equity. Users can publish strategies to a shared marketplace and follow the ones they trust. A free plan resets monthly and paid tiers add more usage.

The research software that values a company is priced and designed for professional analysts, so individual investors work from either raw data or unsourced opinions.
