Tracked stocks are saved in this browser. Every time you open the page, the day's close/last price is
appended to that stock's log, and you're told the moment your target is crossed.
For logging that runs even when the page is closed, use tracker.js — cron it just after the 3:30pm IST close (see README).
Probabilities are statistical estimates from past price movement only — they assume the future behaves like the sampled history, and they know nothing about earnings, news, or company fundamentals. Real outcomes routinely fall outside these ranges. This tool is for education and research; it is not investment advice, and it does not place trades.
