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)
`);

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

Native Pine Script	PineTS Syntax (JavaScript)
//@version=5 indicator("RSI Strategy") rsi = ta.rsi(close, 14) sma = ta.sma(rsi, 10) plot(rsi, "RSI") plot(sma, "Signal")	//@PineTS indicator('RSI Strategy'); const rsi = ta.rsi(close, 14); const sma = ta.sma(rsi, 10); plot(rsi, 'RSI'); plot(sma, 'Signal');

• Williams Vix Fix : Volatility-based indicator
• Squeeze Momentum : Momentum oscillator
• Playground : Test your own Pine Script code

Demos are Built with PineTS + QFChart

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))
`);
