Fefi

Available at fefi.ai, the platform brings together stock screening, options analysis, trading backtesting, real-time financial monitoring, and professional finance interview simulation capabilities that would typically require multiple separate subscriptions into a single free platform designed to democratize access to professional-grade financial intelligence.

The platform's AI stock screener filters the investment universe based on user-defined criteria including valuation metrics, fundamental financial ratios, growth indicators, and technical signals.

This screening capability allows investors to systematically identify stocks that match specific investment theses without manually reviewing thousands of companies.

The screener connects to live market data to ensure that filtering results reflect current market conditions rather than historical snapshots that may no longer be accurate.

Fefi's options analysis tools provide access to contract details, option chains, and pricing data across different strike prices and expiration dates information critical for options traders evaluating potential positions.

The platform's trading backtester includes an integrated code editor that allows users to write and test custom trading strategies against real historical market data.

This backtesting environment enables strategy validation before committing capital, helping investors identify whether a particular approach would have been profitable historically under various market conditions.
