**qPACE**: The all-in-one quantitative toolkit powered by Rust - usable from Python, Node.js, and the browser.

- Cross‑language, cross‑platform - high‑performance Rust core with the fully typed API for Python, Node.js (NAPI), and Browser (WebAssembly).

- Extremely fast backtesting engine - millions of bars per second. Export exact trades back to Pine for one‑click visual validation.

- Technical Analysis - more than 30 indicators fully compliant with TradingView results, written in [Pine](/content/ta.pine) and compiled using our [compiler](#pine-from-pythonjavascript).

- Data layer - resampling/aggregation, zipping/unzipping, reading/writing from CSV/Parquet, and more.

- Cross-ecosystem - interoperable with Pandas, Polars, and more.

- CLI + upcoming UI

## Installation

### Python

```bash
pip install qpace
```

### JavaScript

```bash
npm install qpace
```

## Quick Example

Python

```python
import qpace as qp

ohlcv = qp.Ohlcv.read_csv("btc.csv")
ctx = qp.Ctx(ohlcv, qp.Sym.BTC_USD())
rsi = qp.ta.rsi(ctx.copy(), ohlcv.close, 14)
```

Node.js

```javascript
import * as qp from "qpace/node";

const ohlcv = qp.Ohlcv.readCsv("btc.csv");
const ctx = new qp.Ctx(ohlcv, qp.Sym.BTC_USD());
const rsi = qp.ta.rsi(ctx.copy(), ohlcv.close, 14);
```

## Pine from Python/JavaScript

We designed and developed in-house Pine Script compiler that takes your original Pine Script code and compiles it to efficient rust code that is later exposed to Python, Node.js and Web/WASM with type hints. Easy interface and practically no hustle from your side. Our compiler supports any technical analysis indicator and strategy, while having extreme performance.

- bot automation
- machine learning
- backtesting
- parameter optimization
- and much more

[Get started](https://qpace.dev)

`script.pine`

```pine
//@version=5
library("MyLibrary")

export custom_ma(series float src, int length) =>
    ta.ema(ta.change(src) * volume, length)
```

Python:

```python
import qpace as qp
import my_library as pine

ctx = qp.Ctx(ohlcv, qp.Sym.BTC_USD())
custom_ma = pine.script.custom_ma(ctx.copy(), ohlcv.close, 14)
print(custom_ma) # [1.0, 2.0, ...]
```

Node.js:

```javascript
import * as qp from "qpace/node";
import * as pine from "my_library"; 

const ctx = new qp.Ctx(ohlcv, qp.Sym.BTC_USD());
const customMa = pine.script.custom_ma(ctx.copy(), ohlcv.close, 14);
console.log(customMa); // [1.0, 2.0, ...]
```

## Suite

**qPACE Suite**: Free collection of the best indicators and strategies (separate package to `qpace`).

Python:

```bash
pip install qpace_suite
```

JavaScript:

```bash
npm install @qpace/suite
```
