What is PineTS?

PineTS is an open-source transpiler and runtime that brings Pine Script to JavaScript ecosystem. Write indicators once, run them anywhere : on your own servers, in the browser, or embedded in your trading applications.

``

javascript

import { PineTS, Provider } from 'pinets';



const pineTS = new PineTS(Provider.Binance, 'BTCUSDT', '1h', 100);



// Run native Pine Script directly

const { plots } = await pineTS.run(

//@version=5
indicator("EMA Cross")
plot(ta.ema(close, 9), "Fast", color.blue)
plot(ta.ema(close, 21), "Slow", color.red)

);

Why PineTS?



| Challenge                                   | PineTS Solution                                      |

| ------------------------------------------- | ---------------------------------------------------- |

| Pine Script only runs on TradingView        | Run indicators on your own infrastructure            |

| Can't integrate indicators with custom apps | Full JavaScript/TypeScript integration               |

| Limited to TradingView's data sources       | Use any data source (Binance, custom APIs, CSV)      |

| No programmatic access to indicator values  | Get raw values for backtesting, alerts, ML pipelines |

| Can't run indicators server-side            | Works in Node.js, Deno, Bun, browsers                |

Quick Start



$3

bash

npm install pinets

$3

javascript

import { PineTS, Provider } from 'pinets';



// Initialize with Binance data

const pineTS = new PineTS(Provider.Binance, 'BTCUSDT', '1h', 100);



// Calculate a simple moving average

const { plots } = await pineTS.run(

//@version=5
indicator("My First Indicator")
sma20 = ta.sma(close, 20)
plot(sma20, "SMA 20")

);



console.log('SMA values:', plots['SMA 20'].data);





That's it! You're running Pine Script in JavaScript.
