  • [IMPROVEMENTS] Instead of calculating changes in positions and orders, Jesse now uses data on the exchange to stay in sync in real-time.
  • [NEW FEATURE] Added persistency support to the live mode. Jesse is now able to stop and start at a later time without starting from scratch.
  • [NEW FEATURE] Added is_stop_loss and is_take_profit properties to the Order class. Useful for detecting the role of the executed order in methods such as on_close_position()open in new window.
  • [BREAKING CHANGE] Dependencies are now locked. So from this version forward, doing pip install jesse will force your dependencies to be the same as the current version's requirements. This is to prevent you from installing a different version of the dependencies leading to unexpected behavior.
  • [NEW FEATURE] The position table now displays the liquidation price of the position in the live trading dashboard.
  • [NEW FEATURE] Added has_long_entry_orders and has_short_entry_orders properties to the Strategy class. They are used for knowing the type of entry orders for times that position is not opened yet such as inside the should_cancel() and before() methods and also in filters.

  • [New FEATURE] Added a new "Report" button that is available during live sessions for submitting a report alongside logs of your running session. The previous report button was only available if an exception was raised causing the session to stop. This one is always available.
  • [IMPROVEMENT] Exception tracebacks are now logged in the info logs and included in the reports helping us to track down bugs.
  • [IMPROVEMENT] Strategies can now be long-only. That means should_short() and go_short() are optional. If you don't implement them, the strategy will be long-only.

  • [NEW FEATURE]: A "Hyperparameters" section is displayed in backtest results if the strategy has any hyperparameters defined.
  • [NEW FEATURE] Added Bybit Perpetual driver for live trading.
  • [NEW FEATURE]: Added support for PostgreSQL ssl mode via POSTGRES_SSLMODE environment variable. PR submittedopen in new window by Chirica Gheorgheopen in new window. Thanks Chirica!
  • [IMPROVEMENT] Sends notification for the "reconnect" message of the WS connection in live mode
  • [IMPROVEMENT] Strategy execution for update_position is paused for 3 seconds if an order execution event was received before update_position was called. Reduces the number of unexpected behavior in live mode.
  • [IMPROVEMENT] Doesn't log fee-charging if fees are set to zero. Makes it easier to read the logs when developing.

  • [Improvement] Automated "handling of take-profit and stop-loss that are priced the opposite of what they are supposed to" in strategies by closing the position instead of raising an exception causing the session to terminate.
  • [Improvement] Added support for cancelling (remaining) entry orders in update_position()
  • [Improvement] Error logs are now logged as info logs as well so info logs now include all the logs.
  • [FIX] Fixed Discord notifications not working

0.30.0 (GUI Dashboard)

  • [NEW FEATURE] GUI Dashboard is now available and replaces the CLI.
  • [NEW FEATURE] Docker setup is improved and is now a first-class citizen of Jesse and is shipped with all newly created Jesse projects. It enabled you to run Jesse with one single command!
  • [NEW FEATURE] Sending feedback and exception reports with optional log-file attachment right from within the dashboard.
  • [NEW FEATURE] Responsive design which makes it easy to use even on mobile devices (if you install Jesse on a remote server)
  • [NEW FEATURE] Added average execution time for optimizing mode
  • [NEW FEATURE] All main forms of the dashboard remember your inputs. So repeating backtests, etc is much easier with a click of a button

  • [Improvement] The error handling is now much more robust and reliable.
  • [Improvement] Every time you run an action like a backtest, the action is run in a separate process. This means that the action is not blocking the main process; hence, the main process can continue to run even if an error occurs. One example good that comes out of this is that notifications are now more reliable.
  • [Improvement] Installation of the live-trade plugin is now fully automated. No need to manually find your machine's info, download, and install.
  • [Improvement] Faster backtest execution with the debug mode enabled because of no actual terminal printing
  • [Improvement] Improved handling of database connections
  • And much more! This was the biggest release yet.

TIP

Starting from version 0.30.0, this page will include changelog of the live-trade plugin as well.

0.29.1

[Improvement] Change Python version validation to recognize 3.10 (understood it as 3.1 before) [Improvement] The CSV created from the optimization mode now uses tab delimiter, as sometimes chars from the DNA would mess up the file. [Improvement] The CSV created from the optimization mode now includes all metrics from the backtest. [Improvement] Added missing REQUIRED_PACKAGES to setup.py [DEPRECATED] 3D and Week candles have been removed, as they differed from the exchange.

0.28.0

  • [BREAKING CHANGE] on_take_profit() and on_stop_loss() event methods have been removed, and replaced with the on_closed_position() method.
  • [Improvement] If the price difference between the current price and order price are significantly small (less than 0.01%) Jesse will use a MARKET order instead of LIMIT or STOP. This probably has no effect on your backtests but prevents some communication errors from exchange's side in live trading mode.
  • [Improvement] Replaced crypto_empyrical package with quantstats. This means now the metrics in Jesse's metrics report and Quantstat's HTML reports should be identical.
  • [NEW FEATURE] Added smart sortino, smart sharpe and serenity options for the optimize mode's fitness metric.

0.27.3

  • [NEW FEATURE] Add support for FTX Futures exchange's perpetual futures trading (both live-trade and backtest).
  • [NEW FEATURE] Add initial support for Bybit Perpetuals driver (backtest only).
  • [NEW FEATURE] Added wavelet_denoising() utility function.
  • [Improvement] Can handle many of order rejection events that sometimes happen from exchange's side instead of requiring to restart your live session.

0.26.0

  • [IMPROVEMENT] Added support for M1 macs.
  • [CHANGE] The numba package has become an optional package which was a requirement for supporting M1 macs. Now numba won't be installed by default. This means, if you are an M1 user, you don’t have to install numba and you can install Jesse as before and it will work just fine. If you are NOT an M1 user, then you can still take advantage of numba by installing it through running pip install numba.

  • [Improvement] Rounding for live or paper now uses the required precision from the exchange. Could have caused exceptions before for coins with exotic precision requirement.
  • [Improvement] risk_to_qty and size_to_qty now round the qty down. As in some conditions the qty would otherwise exceed the self.available_margin / self.capital leading to the InsufficientMargin exception.
  • [Improvement] risk_to_qty now also accepts precision parameter.
