duka_dl 0.1.1

A fast and simple downloader for Dukascopy

Duka-DL

Dukascopy is known for its high-quality, tick-level historical market data, which is excellent for backtesting trading strategies. However, downloading this data for long periods is a tedious manual process of downloading, saving, and resampling individual daily files.

Duka-DL automates this entire workflow. It is a free, fast, and simple command-line tool that fetches data for each day in your specified range and consolidates it into a single, clean CSV or Parquet file, ready for analysis.

Installation

Install the package directly from PyPI:

pip install duka-dl

Usage

Using the tool is straightforward. You can specify a symbol, start date, and end date.
