Practical overview
When it fits
Use it when building a web interface that needs a customizable candlestick chart and you can provide correctly ordered timestamped market data. Consider its stated unmaintained status when choosing a dependency for new software.
Who it is for
- Developers building trading software or financial-analysis interfaces.
- Developers who need to visualize timestamped price and volume data with custom indicators or annotations.
Documented uses
- Render candlestick charts from OHLCV data.
- Add custom indicator series above or below the main chart.
- Draw custom visualizations using chart coordinate-mapping functions and the JavaScript canvas API.
- Display non-time-based charts such as Renko.
Requirements & limits
The repository identifies the project as open source under the MIT license. It documents installation through npm or a browser script.
- The library renders supplied data; the documentation does not describe it as a market-data provider or exchange.
- Main chart rows must be sorted by time and cannot contain duplicate timestamps.
- Indicators may be shown on the chart or in a separate panel below it.
- The repository says the project is not maintained.
- The README documents npm and browser-script installation options.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare chart data for TradingVue.js
Structure timestamped OHLCV data and optional indicators for display in a chart.
Before you start
- JavaScript project using TradingVue.js
- Main OHLCV rows with timestamp, open, high, low, close and volume
- Rows sorted by ascending timestamp, with no duplicate timestamps in the main OHLCV series
Steps
Create a chart data object with a chart section containing the chart type and OHLCV rows.
Add optional timestamped indicator series under onchart for overlays or offchart for indicators displayed below the chart.
Provide the chart object to the TradingVue component as its data.
Expected outcome
A data structure prepared for rendering a chart and optional indicator series.
Guide limitations
- The repository states that the library is not maintained.
- This recipe covers data preparation and component use, not a tested deployment or a source of market data.
