  • RSI now handles flat and one-sided price moves correctly — RSI results now stay accurate when prices only rise, only fall, or remain unchanged — including returning 100 during steady gains and 0 during steady losses.
  • psarAdded the Parabolic Stop and Reverse (PSAR) indicator to the library.
  • rsiFixed RSI calculations so steady, flat, or one-sided price moves now return valid results.
  • psarExported PSAR from the main package and added TypeScript declarations for its inputs and results.

Wilder Smoothing fix and improved TypeScript types

Shipped3 commits+26−22
  • Wilder Smoothing now waits for enough data — Early indicator values are now left unset until enough data points are available, which makes the output more accurate and easier to interpret.
  • indicatorsFixed Wilder Smoothing so early values stay unset until there is enough data to calculate a result.
  • typescriptAdjusted indicator result typings so they better match the values returned by the library.
  • typescriptUpdated indicator type definitions to include timestamp inputs and improved result typing.

New indicators, chart types, and precision controls

Shipped32 commits+5682−803
  • ADX trend-strength indicator added — You can now calculate the **Average Directional Index (ADX)**, along with the smoothing method it depends on, to better measure trend strength.
  • More chart types are now available — This week adds support for **Renko** and **Heikin-Ashi** charts, expanding the ways you can visualize market movement.
  • Custom numeric precision for outputs — Indicator values can now be formatted with a configurable number of decimal places, which is especially useful for assets that need more precision.
  • indicatorsAdded the Average Directional Index (ADX) for measuring trend strength.
  • chartsAdded Renko chart support, including fixed-brick and ATR-based brick sizing.
  • chartsAdded Heikin-Ashi chart calculations and exposed them through the main package export.
  • indicatorsAdded the Commodity Channel Index (CCI), VWAP, and Force Index indicators.
  • configurationAdded configurable numeric precision for indicator output.
  • apiAdded `setConfig` and `getConfig` so applications can customize library behavior.
  • apiUpdated ADX results to return the ADX, positive directional index, and negative directional index together.
  • apiUpdated CCI so `nextValue` can accept candle data.
  • apiCandle data and candle lists now include timestamps and volume values.
  • indicatorsImproved true range and moving average calculations for more consistent ADX results.
  • indicatorsFixed several indicators so zero values are handled correctly instead of being treated as missing data.
  • indicatorsFixed KST and ROC so they handle price data more reliably, and removed invalid ROC values from output.
  • chartsFixed Renko brick calculations so they use the correct reference price and track highs, lows, and volume more reliably.
  • documentationImproved setup guidance for older Node.js versions and browser usage, including when `babel-polyfill` is needed.
  • buildAdded a browser playground example to make local testing easier.
  • buildStandardized the Renko file name for consistency and updated build test coverage.
  • documentationUpdated the README with corrected examples for SMA and bullish pattern helpers.
  • documentationAdded ADX, Renko, Heikin-Ashi, and CCI examples to the README and indicator list.

Packaging and browser build updates for technicalindicators

Shipped4 commits+1257−1885
  • Built-in LinkedList support removes an external dependency — technicalindicators now includes its own LinkedList utilities, so you no longer need to install the separate `linkedlist` package.
  • Browser builds now require a new entry point and `babel-polyfill` — The browser bundle was moved to `dist/browser.js` and now depends on `babel-polyfill`, so existing browser imports may need to be updated.
  • packageAdded built-in LinkedList support, removing the need for the external `linkedlist` package.
  • browserSwitched the browser build to Rollup for a cleaner bundled file.
  • packageAdded TypeScript typings for the internal linked list utilities.
  • apiImproved package exports so the library can be imported more reliably with modern JavaScript tooling.
  • apiPackage entry points now use the compiled library files, so custom import paths may need to be reviewed.
  • browserBrowser usage now points to `dist/browser.js` and requires `babel-polyfill` as an external dependency.
