Candlestick in Vue

Open, high, low and close, one row a day

type: 'candlestick', measures: [open, high, low, close]

This draws a candlestick chart, one candle a day from open, high, low and close, with a price axis on the right, zoom and pan, and a drawing rail for trend lines, channels, Fibonacci retracements and measuring a range. It shows a market's daily range and direction in the form traders read, straight from the grid's rows.

Building…

Loading a live grid…

This is the Vue 3 version. A createLatticeGrid component takes the configuration through v-bind, and reactive data flows straight into the grid, so it updates the way the rest of your Vue app does.

The configuration

<link rel="stylesheet" href="https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.min.css">
<style>
  #chart { height: 320px; }
  #grid { margin-top: 14px; }
  #grid > div { height: 320px; }
</style>
<div id="app"></div>

<script type="module">
  import * as Vue from 'https://esm.sh/vue@3/dist/vue.esm-browser.prod.js';
  import { createGrid } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.esm.min.js';

  const LatticeGrid = createLatticeGrid({ vue: Vue, createGrid });

  Vue.createApp({
