PFeed: Data Pipeline for Algo-Trading, Getting and Storing Real-Time and Historical Data Made Easy.

Problem

Starting algo-trading requires reliable, clean data. However, the time-consuming and mundane tasks of data cleaning and storage often discourage traders from embarking on their algo-trading journey.

Solution

By leveraging modern data engineering tools, pfeed handles the tedious data work and outputs backtesting-ready data, allowing traders to focus on strategy development.

---

PFeed (/piː fiːd/) is a data pipeline for algorithmic trading, serving as a bridge between raw data sources and traders. It enables you to download historical data, stream real-time data, and store cleaned data in a local data lake for quantitative analysis, by automating the processes of data collection, cleaning, transformation, and storage.

Core Features

• Download or stream reliable, validated and clean data for research, backtesting, or live trading
• Get historical data (dataframe) or live data in standardized formats by just calling a single function
• Own your data by storing them locally using MinIO, with the option to connect to the cloud
• Interact with different kinds of data (including TradFi, CeFi and DeFi) using a unified interface

Installation

For more installation options, please refer to the documentation.

# [RECOMMENDED]: Full Features, choose this if you do not care about the package size
pip install -U "pfeed[all]"

# Minimal Features, only supports getting, downloading and streaming data
pip install -U "pfeed[core]"

Quick Start

1. Get Historical Data in Dataframe (No storage)

Get Bybit's data in dataframe, e.g. 1-minute data (data is downloaded on the fly if not stored locally)

import pfeed as pe

feed = pe.BybitFeed(data_tool='polars')

df = feed.get_historical_data(
    'BTC_USDT_PERP',
    resolution='1minute',  # 'raw' or '1tick'/'1t' or '2second'/'2s' etc.
    start_date='2024-03-01',
    end_date='2024-03-01',
)

Printing the first few rows of df:

	ts	product	resolution	open	high	low	close	volume
0	2024-03-01 00:00:00	BTC_USDT_PERP	1m	61184.1	61244.5	61175.8	61244.5	159.142
1	2024-03-01 00:01:00	BTC_USDT_PERP	1m	61245.3	61276.5	61200.7	61232.2	227.242
2	2024-03-01 00:02:00	BTC_USDT_PERP	1m	61232.2	61249	61180	61184.2	91.446

By using pfeed, you are just a few lines of code away from getting a standardized dataframe, how convenient!

2. Download Historical Data on the Command Line Interface (CLI)

For more CLI commands, please refer to the documentation.

# download data, default data type (dtype) is 'raw' data
pfeed download -d BYBIT -p BTC_USDT_PERP --start-date 2024-03-01 --end-date 2024-03-08

# download multiple products BTC_USDT_PERP and ETH_USDT_PERP as minute data and store them locally
pfeed download -d BYBIT -p BTC_USDT_PERP -p ETH_USDT_PERP --dtypes minute --use-minio

3. Download Historical Data in Python

import pfeed as pe

# compared to the CLI approach, this approach is more convenient for downloading multiple products
pe.download(
    data_source='bybit',
    pdts=[
        'BTC_USDT_PERP',
        'ETH_USDT_PERP',
        'BCH_USDT_PERP',
    ],
    dtypes=['raw'],  # data types, e.g. 'raw', 'tick', 'second', 'minute' etc.
    start_date='2024-03-01',
    end_date='2024-03-08',
    use_minio=False,
)
