duka - Dukascopy data downloader Build Status

Finding good Forex data is difficult or expensive. Dukascopy has made available an excellent web tool to download tick data for a large a variety of Forex, CFD and commodities. This is awesome and extremely useful for people, like me, trying to study the Forex market. However, it takes a lot of time to download a large data set from the website because you can download only one day per time. In order to solve this issue, I created duka.

duka is a small terminal application that can be used to download ticks for a given date range from the Dukascopy historical data feed for one or more symbols. duka takes advantage of python threads and coroutine in order to speed up the download. It takes roughly 10m to download tick data for one year for a given instrument. No bad :)

Key features :

  • Ticks data with volumes
  • Candle formatting with different time-frames ( from 1 minute to 1 day )
  • CSV output
  • multi-thread support
  • Large variety of symbols

This is what duka looks like:

As you can see, duka estimates the time left until the download is completed. This is extremely useful when downloading a large data set.

I hope you enjoy it!!

Examples

  • Help

    duka -h

  • Download last available tick set (i.e. yesterday if not Saturday ) for EURUSD and GBPUSD

    duka EURUSD GBPUSD

  • Download ticks for the EURUSD for a specific day

    duka EURUSD -d 2016-02-02

  • Download ticks for the EURUSD between two dates. For example:

    duka EURUSD -s 2015-01-01 -e 2016-12-31

    download all ticks for the 2015 year

  • We can specify only the start date. The default end date will be today. For example:

    duka EURUSD -s 2016-01-01

    downloads all ticks from the beginning of the year until now.

All data is saved in the current folder. You can also specify the number of threads to be used by setting the t option. I recommend not to use too many threads because you might encounter problems opening too many connection to the server.
