Real data. Daily bars for 10 US large-caps (AAPL, MSFT, NVDA, AMZN, WMT, JPM, GS, XOM, JNJ, PFE), Nov 2014 – Nov 2017, from aCC0 public-domain dataset. P/E is derived from SEC EDGARfilings and only becomes visible on each 10-K's filing date — no look-ahead.
Data ends in 2017 because it's the newest daily OHLCV that is genuinely free to redistribute. The engine ships no data of its own —bring your own.

Hold the 3 names trading at the highest 2-day average close — a light momentum tilt, and the simplest thing that isn't “own everything.”
Ready — runs in your browser on real data.
