• Remove --one-shot feature, use the loop instead.

4.4.4 - 2021-11-16

Added

• Add --version option.

Fixed

• The Telegram sender would not shut down gracefully. I have fixed that now.

4.4.3 - 2021-11-15

Fixed

• I've accidentally deleted the source code. This should be fixed now.

4.4.2 - 2021-11-15

Changed

• Streamlit doesn't easily work on the Raspberry Pi due to issues with py-arrow and the ARM CPU. I have therefore reverted these dependencies to be an extra again.

4.4.1 - 2021-11-15

Changed

• More refactoring. Also update the versions of various dependencies. The Streamlit interface is now part of the main dependencies.

4.4.0 - 2021-11-05

Added

• Add test-drive command to verify configuration.

Changed

• Major architectural change, without changes to the user.

4.3.5 - 2021-09-20

Fixed

• When the balance on the marketplace is zero, withdrawals would fail and therefore crash the whole program. This is now fixed.

4.3.4 - 2021-08-26

Added

• I now use the mypy static analysis and type checker, and also found a few subtle bugs with that in code paths which aren't used often.

Fixed

• The --dry-run option would write buys into the database, although it would not buy anything on the market. Now the database should now be changed.

4.3.3 - 2021-08-12

Fixed

• Due to an incomplete refactoring the program would crash whenever there was a non-fatal exception regarding the marketplace. This should be fixed now.

4.3.2 - 2021-08-02

Changed

• Make the marketplace package isolated, only expose a limited set of attributes in __init__.py.

Fixed

• Fix automatic detection of Telegram chat ID.
• Do not crash when there is no balance at Kraken.
• Also handle requests.exceptions.HTTPError.

4.3.1 - 2021-07-19

Fixed

• Apparently all Kraken trades were sent in the validation mode. I have tried to fix that.

4.3.0 - 2021-07-16

Added

• Add a start attributes to triggers.
• Add --dry-run option to watch command such that it can be tested without spending money.
• Allow specifying delay and cooldown not only in minutes as delay_minutes and cooldown_minutes, but also as delay_hours, delay_days, cooldown_hours and cooldown_days.
• Add documentation for cron to Configuration.
• Introduce a new pre-commit hook that sorts the import statements.

Fixed

• Remove double reports of connection errors.
• In case that the user has no drop triggers, the database cleaning interval is set to 120 minutes.
• Handle requests.exceptions.ConnectionError without crashing.
• Fix --one-shot mode. It would previously sleep for another interval and not shut down the Telegram logger, preventing the program from a clean exit.

4.2.4 - 2021-06-18

Fixed

• Also handle ReadTimeout errors that can happen when the API doesn't answer before the connection breaks. These have been ignored previously, but now the error message is a bit cleaner.

4.2.3 - 2021-06-18

Added

• Log output is also put into the Linux system log. In this way one can do post-mortem debugging.

Changed

• Telegram messages are no longer directly send but stored in a send-queue. This way connection outages do not yield lost messages but rather just delay sending.
• Use a proper form instead of the plain button in Streamlit.

Fixed

• Crashes have been reported when the Telegram message was longer than their limit of 4096 characters. Messages are now chunked to prevent this from happening.

4.2.2 - 2021-05-25

Fixed

• Another warning message would use a constant that was moved to another place in the meantime. The program crashed when the message was going to be emitted. It has been removed now.

4.2.1 - 2021-05-23

Fixed

• When a trigger was disabled after three consecutive failures, a message stating that would be shown every time the trigger was processed. In this way the user got the same amount of messages. This message is now removed.

4.2.0 - 2021-05-21

Added

• Triggers can be given names in the evaluation interface.
• For the Kraken marketplace you can now specify whether the fees should be applied to base or quote currency.
• Attach a stack trace of exceptions to the Telegram message.
• In the drop survey evaluation one now also has a time range slider such that one can get a feeling for the drops.

Changed

• The reported balance at startup will only contain currencies which are used in triggers.
• The legend in the trigger simulation plot is shown below the plot to allow for longer trigger names without having them cropped.
• Failed triggers are just silenced for 12 hours. Another attempt is made automatically afterwards.
• clikraken has been retired and we now use krakenex in version 2.
• Send Telegram messages via POST (and not GET).
• Automatically move the SQLite database into the appropriate user data directory on Windows on macOS, no change on Linux.

Fixed

• Historical API was broken, it now retrieves data again.
• Specifying a lower-case fiat currency and using the percentage based fiat volume strategy led to an error.
• Make sure that errors from the Telegram API are reported and not ignored.
• Do not use Markdown with Telegram as parsing errors prevent messages from being sent.
• Errors from the historical price source have been silently ignored. They now issue a warning.

4.1.0 - 2021-05-05

Added

• Add automatic withdrawal for currency when the amount exceeds a certain threshold determined by the fee.

Changed

• Use krakenex instead of clikraken to communicate with Kraken. The old implementation is deprecated but retained with --marketplace clikraken.

4.0.0 - 2021-05-04

Changed

• The trigger specification is significantly changed. Consult the documentation to learn about the new format.

3.5.1 - 2021-05-03

Fixed

• Fix drop trigger with percentage such that volume_fiat is actually a percentage and not a ratio (between 0 and 1).

3.5.0 - 2021-05-03

Added

• Add --one-shot to the watch subcommand to only run the watch loop once.
• Add fiat_percentage: true option to create drop triggers that use a percentage of the available fiat balance instead of a fixed volume.

Changed

• Update documentation and state paths to the configuration file on various platforms.

3.4.0 - 2021-04-27

Added

• Query balances on the marketplace at startup and after each trade. A notification is send such that you always know how much fiat money is left to trade.

Changed

• Reflect change from XBT to BTC coding on Kraken.
