qpace 0.2.5

📊 The Quant SDK for Python and Javascript. Written in Rust.

qPACE

The Quant SDK for Python · JavaScript · Rust

From research to production - all in one toolkit.

---

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 and compiled using our compiler.

• 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

pip install qpace

JavaScript

npm install qpace

Quick Example

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

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

script.pine

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

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

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:

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, ...]
