# Changelog

Here you can see that changes were made at each release.

# 0.25.0

  • [NEW FEATURE] Introduces a plugin-based system for exchange drivers.
  • [BREAKING] Requires a plugins.py present in the project.
  • [CHANGE] Adjustments in the candle store as was required by the live trade mode.
  • Minor bug fixes

# 0.24.0

  • [NEW FEATURE] Added new utility functions that are used in statistical analysis of the prices such as for writing statistical arbitrage strategies: z_score, are_cointegrated, prices_to_returns
  • [IMPROVEMENT] Refactored how we execute routes in the live trade mode so the order of execution is the same as defined in the routes.py file. This makes it possible to write strategies that depend on it such as statistical arbitrage.
  • [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

# 0.23.0

  • [NEW FEATURE] Added self.log method for easier logging from withing the strategy file.
  • [NEW FEATURE] Added new properties to the Strategy API: liquidation_price, mark_price, funding_rate, next_funding_timestamp
  • [NEW FEATURE] Implemented the liquidation mechanism for the isolated mode in backtests, and both isolated and cross in live mode.
  • [NEW FEATURE] New indicators: Jurik Moving Average, Chande Kroll Stop, Choppiness Index, Pascals Weighted Moving Average, Symmetric Weighted Moving Average, Bandpass filter, Inverse Fisher Transform applied on RSI, KDJ
  • [NEW FEATURE] devstop, rvi, and zscore indicators now let you choose the devtype.
  • [Improvement] Packages updated - Update matplotlib from 3.4.1 to 3.4.2, Update numpy from 1.20.2 to 1.20.3, Update ta-lib from 0.4.19 to 0.4.20, Update websocket-client from 0.59.0 to 1.0.1, Update click from 7.1.2 to 8.0.1
  • [Improvement] Available matypes used in some indicators extended.
  • [Improvement] Improved handling of none string values in the logger

# 0.22.0

  • [BREAKING CHANGE] For consistency ta.vwmacd now accepts signal_period instead of signalperiod
  • [Improvement] Updated Docker images. By TheCrazyLex (opens new window).
  • [Improvement] Packages updated - scipy from 1.6.2 to 1.6.3, arrow from 1.0.3 to 1.1.0, quantstats from 0.0.30 to 0.0.32, websocket-client from 0.58.0 to 0.59.0, quantstats from 0.0.32 to 0.0.34, pytest from 6.2.3 to 6.2.4
  • [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.
  • [Improvement] The full report (quantstats) now uses 365 trading days for the metrics which makes its calculations crypto friendly. By sbkhosh (opens new window) and mblum (opens new window).

  • [FIX] Error in ta.minmax solved. Namedtuple changed: min -> is_min and max -> is_max

  • [NEW FEATURE] New indicator: Polarized Fractal Efficiency (PFE)

# 0.21.3

  • [NEW FEATURE] Added HTML reports with a more complete set of metrics and charts enabled by the --full-reports flag in your backtests. By nicolay-zlobin (opens new window).
  • [NEW FEATURE] New indicators: Elder Ray Index (ERI), ttm_trend, kurtosis, mean_ad, median_ad, skewness
  • [Improvement] Added a check for the right symbol format (with dash) for the import candle mode - preventing possible confusion and resulting errors.
  • [Improvement] A @cached property has been added to improve performance and avoid unnecessary repeated calculations. It's applied where sensible in the Strategy class and available via import to be used on indicators inside a users Strategy as well. Some strategies might see a huge boost because of this.
  • [Improvement] All indicators now use the helper functions same_length and slice_candles.
  • [Improvement] self.metrics is now only calculated if a trade happened leading to a performance boost.
  • [Improvement] The old way of working with strings in python (format) has been replaced with much faster f-strings leading to a performance boost.
  • [FIX] Incorrect InsufficientMargin exceptions that were caused by reduce_only orders.
  • [FIX] An error with the json export of the backtest that occurred is now fixed.
  • [FIX] Using futures mode you had to add all the used assets to the config.py file - although that should have only been needed for spot mode. This is not necessary anymore. Additionally the spot mode now gives clearer error if assets are missing in the config.
  • Multiple preparations for the live trade plugin. Other modes are unaffected by them.

# 0.20.0

  • New timeframes: 45m, 12h, 3D, 1W
  • [Improvement] The indicators now use the configured warmup_candles
  • [FIX] Spot should work no again thanks to a fix by discohead (opens new window)
  • [FIX] Sometimes users faced a InsufficentMargin error - this was caused by a small bug in the handling leverage of market orders.
  • [Improvement] Durations are now displayed without decimals. By maebert (opens new window)
  • [Improvement] The crossed utility should be a little faster now, as we only use numpy there now.
