# Run Pine Script® on Your Own Chart: Vela™ + PineTS

> Vela™ is the open-source charting library; Vela-PineTS runs native Pine Script® v5 and v6 on it. Paste the script, get the indicator, with inputs, alerts, strategies and request.security() handled. Three packages, exact API, published licensing.

Vela™ is our open-source charting library. Vela-PineTS runs native Pine Script® v5 and v6 on it through PineTS, our open-source runtime. The indicators your users already know, in your app, on your infrastructure. Proof: the most-used indicator on TradingView, Smart Money Concepts by LuxAlgo, executes unmodified through PineTS on LuxAlgo charts; the whole LuxAlgo Library does.

## Setup

```bash
npm install @luxalgo/vela @luxalgo/vela-pinets pinets
```

```ts
import { Vela } from '@luxalgo/vela';
import { PineWorkerEngine } from '@luxalgo/vela-pinets';

const chart = new Vela('#chart', { symbol: 'BTCUSDT', timeframe: '60', live: true })
  .registerEngine('pine', new PineWorkerEngine());

chart.addIndicator(`//@version=6
indicator("EMA 20", overlay=true)
plot(ta.ema(close, 20), color=color.orange, linewidth=2)`);
```

## What runs

- Pine Script® v5 and v6 source, unmodified: the bar-by-bar execution model, series indexing, var/varip, na and barstate behave as the language defines them.
- 800+ Pine Script® API functions implemented and tested, tracked on the public coverage tables at https://docs.luxalgo.com/developers/pinets/api-coverage (70 ta functions alone).
- Inputs become the settings dialog; plots land on the right pane; request.security() resolves through the chart’s cached data feed.
- Live, bar by bar, with persistent engine sessions. Strategies emit trade markers; alert() and alertcondition() fire as host events.
- PineWorkerEngine runs scripts in a Web Worker so heavy indicators never block painting.
