Changelog

Here you can see that changes were made at each release of the main framework and the live plugin:

0.37.0 (10 June 2022)

  • [BREAKING CHANGE] The database tables must be deleted for:
  1. new settings which support spot trading
  2. for new indexing of candles table which now loads X times faster
  • [BREAKING CHANGE] Removed the driver for "Binance Inverse Futures" (known as coin-margined futures on Binance) from the list of supported exchanges for import candles.
  • [BREAKING CHANGE] Updated exchange names to be more similar to what they are on the exchange websites to avoid confusion.
  • [BREAKING CHANGE] Updated the required config object that is passed to the research.backtest() function based on the mentioned changes in this release. Removed the settlement_currency and added 'type'. Read the example on the documentation pageopen in new window for more details.
  • [BREAKING CHANGE] The alias self.capital has been removed to prevent confusion. Please use self.balance instead. Make sure to update your strategies accordingly.
  • [BREAKING CHANGE] The should_cancel() method has been renamed to should_cancel_entry() which is more convenient since it is only used for canceling entry orders. Make sure to update your strategies accordingly.
  • [NEW FEATURE] Added previous_qty property to the Position class.
  • [NEW FEATURE] Added the self.exchange_typeopen in new window, self.daily_balancesopen in new window properties to the Strategy class.
  • [NEW FEATURE] Added self.is_spot_tradingopen in new window and self.is_futures_tradingopen in new window properties to the Strategy class.
  • [IMPROVEMENT] The settlement currency is no longer fixed to USDT or USD. Instead, it is now the quote currency of the symbol you're trading. So it could be USD, USDT, BUSD, BTC (for spot markets), etc.
  • [IMPROVEMENT] The existence of plugins.py is now optional. It has been removed from new projects for the sake of simplicity. If you need to add a driver, you can do so by creating the file manually.
  • [IMPROVEMENT] The "Exchange type", "Leverage", and "Leverage Mode" are now displayed on backtests' result page so you know what the settings have been for the executed backtest.
  • [IMPROVEMENT] Minor improvements to the UI of the dashboard.
  • [FIX] Fixed a bug where generated CSV files in backtests were empty if the export_json option was disabled.

0.36.0 (18 May 2022)

  • [NEW FEATURE] Added new optional parameters to research module's backtest()open in new window function to handle quantstat reports, export hyperparameters, equity-curve chart values, CSV and JSON export, tradingview's pine-editor output and also made chart generation optional so your script can run faster if you don't need it.
  • [IMPROVEMENT] Updated the self.log()open in new window method to NOT send notifications by default in live mode. If you want to, you should pass send_notification=True to the method.
  • [IMPROVEMENT] Improved handling of errors in the REST API for fetching candles in the live mode which was introduced in version 0.35.0.
  • [IMPROVEMENT] Improved handling of the entry_price at FTX to be exactly what you see on their exchange dashboard.
  • [IMPROVEMENT] Improved a few error messages in the live mode to include useful information about the error for easier debugging in the future.
  • [IMPROVEMENT] Added handling of TypeError: 'NoneType' object is not subscriptable errors caused by API keys being expired on Bybit.
  • [IMPROVEMENT] Improved handling of a few common errors in the live mode that are safe to ignore.
  • [IMPROVEMENT] Improved error handling for Bybit drivers in import-candles mode.
  • [IMPROVEMENT] Refactored the notifications handler to work in a separate thread so that in the case of notifications taking long to respond, the main execution won't be affected.
  • [IMPROVEMENT] You will now be asked if you're sure about closing the dashboard. This is to prevent accidental closing of the dashboard tab.
  • [FIX] Fixed a couple of errors happening with notification drivers (Telegram and Discord)
  • [FIX] Fixed a bug where empty log files were created in storage/logs/backtest-mode when running the optimize mode.
  • [FIX] Fixed the ValueError: No value exists in Redis for process ID of: xxx error that occurred in docker setups. It requires you to update your project's docker-compose.yml manually. Here's a quick guideopen in new window.
  • [FIX] Implemented a workaround for an issue when sometimes multiple partially-filled orders in live mode caused unexpected behavior.
  • [FIX] Fixed an issue when paper mode raised an error about API keys of Bybit Perpetuals if their values were empty in the .env file.

0.35.0 (6 April 2022)

  • [NEW FEATURE] Added the import_candles()open in new window method to the "research" module.
  • [IMPROVEMENT] Live mode now uses the REST API of the exchange to fetch candles and update the most recent candles. This is on top of the current Websocket implementation for real-time updates; and is supposed to make Jesse's data storage more reliable.
  • [IMPROVEMENT] Added error handling for Telegram and Discord notifications.
  • [FIX] Fixed the TypeError: decoding to str: need a bytes-like object, int found occurring when resuming the previous live session with open orders on Binance Futures and FTX Futures.
  • [FIX] Fixed a visual bug where the entry price of the positions were displayed incorrectly on the dashboard when live trading.
  • [FIX] Fixed an overflow bug in the daily_balances when using the research module's backtest() function. This did not affect the existing backtest and optimize mode of the GUI dashboard.
  • [FIX] Fixed the bug where the progressbar was not working when importing candles in some browsers.

0.34.0 (24 March 2022)

  • [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] Implemented a "check for newer version" component in the GUI dashboard. So you'll be notified inside the app for newer versions of both the framework and the live plugin. You can skip updates if you choose to.
  • [IMPROVEMENTS] Improved the handling of "PARTIALLY FILLED" orders in the live mode. The new refactor handles them properly, and also you can see in the dashboard the amount of the order that was filled.

0.33.0 (15 February 2022)

  • [NEW FEATURE] Added backtestopen in new window function to the "research" module allowing you to run backtests via your Python script or Jupyter notebook.
  • [NEW FEATURE] Added store_candlesopen in new window function to the research module allowing you to store candles in the database. An example use case is to import candles from a CSV file so you can use them in your backtests.
  • [NEW FEATURE] Added fake_candleopen in new window, fake_range_candlesopen in new window and candles_from_close_pricesopen in new window functions to the research module for generating fake candle data for backtest or other any kind of research.
  • [NEW FEATURE] Added the "More" button for orders in the live mode which opens a slide over the page where you can see all orders.
  • [NEW FEATURE] Added the value of the position (in USDT) to the live dashboard. To use it, hover on the qty of each position.
  • [NEW FEATURE] Added support for running multiple instances of Jesse simultaneously. Useful for those who want to trade using multiple sub-accounts. Just make sure they have different APP_PORT values in their .env file.
  • [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.
  • [IMPROVEMENT] Improved debugging mode in the optimize mode to include a log file that is downloadable at any point in time in the optimization mode.
  • [FIX] Fixed a bug causing optimization sessions to fail. The bug was introduced in the previous release.

  • [FIX] Fixed the TypeError: Argument 'data' has incorrect type (expected list, got dict) error for the Bybit Perpetual driver.
  • [FIX] Improved the way we keep the WS alive for the ByBit driver. No more WS disconnects every 10 minutes (although the reconnecting was working just fine)
  • [FIX] Fixed the AttributeError: 'NoneType' object has no attribute 'watch_list' error for the live plugin.

0.32.0

  • [NEW FEATURE]: Added the watch_listopen in new window function for monitoring custom info in live modes.
  • [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.
  • [FIX] Fixed an issue in multi-threading which led to memory leaks when live trading on Linux machines.

  • [NEW FEATURE] Added all_positions and portfolio_value properties to the strategy API
  • [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
  • [NEW FEATURE] Ability to open multiple tabs (inside the dashboard itself) and run multiple candle importing and backtests in parallel.
  • [NEW FEATURE] You can choose between light and dark mode.
  • [BREAKING CHANGE] Environment variables are now set in the .env file, and application settings are now in the settings section of the dashboard. No more config.py and live-config.py files.
  • [BREAKING CHANGE] DNAs of the optimize mode are now defined in the strategy instead of the routes.py file
  • [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).

  • [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] Minor bug fixes

  • Multiple preparations for the live trade plugin. Other modes are unaffected by them.

0.20.0

  • New indicators: Fibonacci's Weighted Moving Average (FWMA), Sine Weighted Moving Average (SINWMA), Chande Forcast Oscillator (CFO), Kaufman Efficency indicator, High Pass Filter 2-Pole, Supersmoother 3-Pole, Kaufmanstop, Safezonestop, Devstop, RSMK, STC, RVI, VWAP,
