@tidal-ts/core

The part of tidal-ts with no drawing in it: the technical studies, the volatility data layout, bar windows, the adapter for a column-by-column wire format, trading sessions and time zones. Built on pond-ts.

Pre-1.0: pin an exact version. Every @tidal-ts/* package ships on one version number.

• Docs
• Study catalog: every study with a live chart, its settings, and how traders use it

Install

npm install --save-exact @tidal-ts/core @pond-ts/[email protected]
npm install pond-ts@~0.73.0 @pond-ts/financial@~0.73.0

The pond packages are peer dependencies: install them once, on the version this release names in its peerDependencies, so there is only one copy of pond-ts in your bundle.

A study is data

import { applyDerived, deriveId, type DeriveSpec } from '@tidal-ts/core';

const rsi: DeriveSpec = { op: 'rsi', inputs: ['close'], params: { period: 14 } };

// Compute it onto a pond TimeSeries of bars; the values land in this column.
const withRsi = applyDerived(series, [rsi]);
const column = deriveId(rsi);

studyCatalog() lists every study on offer, and opParams, opOutputs and studyLevels describe each one's settings, outputs and guide lines.

To draw it, see @tidal-ts/chart.
