Taiwan 16-Indicator Library — technical, chip, valuation & fundamental in one API
Charting apps show indicators you can only eyeball. The 16-indicator library turns RSI, MACD, KD, Bollinger and OBV — plus chip-flow and valuation indicators charting apps don't have — into a programmable API: deterministic recomputation, open formulas, methodology in every response.
Four families covered
Technical: RSI, MACD, KD, Bollinger, OBV — standard formulas, tunable parameters. Chip flow: institutional cost line, holder concentration, retail-vs-mega divergence. Valuation: PER band, valuation band, yield band. Fundamental: revenue-YoY z-score, margin trend. All deterministically recomputed — same input, same output.
What we deliberately do not do
We do not offer parameter optimisation or ship a 'best' default set. There is no universally correct answer to 14-day versus 9-day RSI; picking one for you quietly injects our preference into your research.
We also do not emit trade signals — golden crosses and overbought/oversold calls stay in your own code. The library returns value series and the calculation window, not conclusions.
