Installation

Standard¶

Install pfeed with your data source, e.g. Bybit, and Ray for parallel processing (recommended):

pip install "pfeed[bybit,ray]"

Windows: enable long paths¶

Windows limits paths to 260 characters by default. pfeed stores data in nested folders (e.g. env=BACKTEST/data_layer=CLEANED/data_domain=MARKET_DATA/...), which together with your data folder can go over that limit.

Run this once in PowerShell as Administrator (right-click PowerShell → Run as administrator):

New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force

Then open a new terminal (restart Windows if the error persists). Python supports long paths, so nothing else is needed.

Advanced¶

Pick only the extras you need:

Combine them in one command:

pip install "pfeed[bybit,ray,prefect]"
