Taiwan Multi-Factor Screener — programmable valuation, chip & fundamental filters
Free screener sites give you fixed dropdowns and eyeball-only results. The multi-factor screener lets you combine valuation percentile, institutional streaks, holder concentration and revenue momentum into one API query, returning the matching list with per-stock hit details.
How conditions compose
Each condition maps to a public indicator on the site — e.g. PER below its 30th historical percentile × foreign net-buy streak ≥5 days × rising mega-holder ratio. Conditions AND-compose with tunable parameters, and every returned stock lists which conditions it hit. Deterministic: same day, same conditions, same list.
How this differs from a free screener site
Most free screeners filter on the latest restated data. Apply a historical condition set to it and the resulting list is contaminated by revisions that postdate the screening date, so the backtest of the rule looks better than the rule was.
Our conditions sit on the snapshot layer: a historical run recomputes from as-of versions, so a screening rule can be backtested honestly. The screener answers which stocks meet your conditions, not what to buy.
