What is PineTS?

PineTS is an open-source transpiler and runtime that seamlessly bridges Pine Script and the JavaScript ecosystem. Develop your indicators once and deploy them everywhere : on your servers, in the browser, or fully integrated into your trading platforms.

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)
`);

About Pine Script™?
Pine Script™ is a domain-specific programming language created by TradingView for writing custom technical analysis indicators and strategies.

Disclaimer : PineTS is an independent project and is not affiliated with, endorsed by, or associated with TradingView or Pine Script™. All trademarks and registered trademarks mentioned belong to their respective owners.

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

Installation

npm install pinets

Hello World

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.

Features

Core Capabilities

Native Pine Script v5/v6 : Run original TradingView code directly (experimental)
60+ Technical Indicators : SMA, EMA, RSI, MACD, Bollinger Bands, and more
Time-Series Processing : Full Pine Script semantics with lookback support
Real-time Streaming : Live data processing with event-based updates
Multi-Timeframe Analysis : request.security() for MTF indicators
High Precision : Matches TradingView's calculation precision

Two Ways to Write Indicators

<table width="100%"> <tr> <th>Native Pine Script</th> <th>PineTS Syntax (JavaScript)</th> </tr> <tr> <td>

//@version=5
indicator("RSI Strategy")

rsi = ta.rsi(close, 14)
sma = ta.sma(rsi, 10)

plot(rsi, "RSI")
plot(sma, "Signal")

</td> <td>

//@PineTS
indicator('RSI Strategy');

const rsi = ta.rsi(close, 14);
const sma = ta.sma(rsi, 10);

plot(rsi, 'RSI');
plot(sma, 'Signal');

</td> </tr> </table>

Live Demos

Usage

Running Native Pine Script

import { PineTS, Provider } from 'pinets';

const pineTS = new PineTS(Provider.Binance, 'BTCUSDT', 'D', 200);

const { plots } = await pineTS.run(`
//@version=5
indicator("MACD", overlay=false)

[macdLine, signalLine, hist] = ta.macd(close, 12, 26, 9)

plot(macdLine, "MACD", color.blue)
plot(signalLine, "Signal", color.orange)
plot(hist, "Histogram", color.gray, style=plot.style_histogram)
`);

// Access the calculated values
console.log('MACD Line:', plots['MACD'].data);
console.log('Signal Line:', plots['Signal'].data);

Using PineTS Syntax

import { PineTS, Provider } from 'pinets';

const pineTS = new PineTS(Provider.Binance, 'ETHUSDT', '4h', 100);

const { plots } = await pineTS.run(($) => {
    const { close, high, low } = $.data;
    const { ta, plot, plotchar } = $.pine;

    // Calculate indicators
    const ema9 = ta.ema(close, 9);
    const ema21 = ta.ema(close, 21);
    const atr = ta.atr(14);

    // Detect crossovers
    const bullish = ta.crossover(ema9, ema21);
    const bearish = ta.crossunder(ema9, ema21);

    // Plot results
    plot(ema9, 'Fast EMA');
    plot(ema21, 'Slow EMA');
    plotchar(bullish, 'Buy Signal');
    plotchar(bearish, 'Sell Signal');

    return { ema9, ema21, atr, bullish, bearish };
});

Real-time Streaming

import { PineTS, Provider } from 'pinets';

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

const stream = pineTS.stream(
    `
    //@version=5
    indicator("Live RSI")
    plot(ta.rsi(close, 14), "RSI")
    `,
    { live: true, interval: 1000 },
);

stream.on('data', (ctx) => {
    const rsi = ctx.plots['RSI'].data.slice(-1)[0].value;
    console.log(`RSI: ${rsi.toFixed(2)}`);

    if (rsi < 30) console.log('Oversold!');
    if (rsi > 70) console.log('Overbought!');
});

stream.on('error', (err) => console.error('Stream error:', err));

Custom Data Source

import { PineTS } from 'pinets';

// Your own OHLCV data
const candles = [
    { open: 100, high: 105, low: 99, close: 103, volume: 1000, openTime: 1704067200000 },
    { open: 103, high: 108, low: 102, close: 107, volume: 1200, openTime: 1704153600000 },
    // ... more candles
];

const pineTS = new PineTS(candles);

const { plots } = await pineTS.run(`
//@version=5
indicator("Custom Data")
plot(ta.sma(close, 10))
`);
