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

  • [NEW FEATURE] Add combinations_without_repeat utility to create unique combinations. Useful for optimize mode.
  • [NEW FEATURE] New indicators: Arnaud Legoux Moving Average, Holt-Winter Moving Average, Natural Moving Average, Ehlers Distance Coefficient Filter, Moving Average Bands, Ulcer Index, Moving Average Adaptive Q, MWDX Average, Variable Length Moving Average, Square Root Weighted Moving Average, Squared Weighted Moving Average, Variable Power Weighted Moving Average, Cubed Weighted Moving Average, JSA Moving Average, End Point Moving Average, Ehlers Predictive Moving Average, Wavetrend, Hurst Exponent
  • [NEW FEATURE] - New Moving Averages added to the ma indicator.
  • [Improvement] Minor code optimizations.
  • [Improvement] Packages updated - Update websocket-client from 1.1.0 to 1.1.1, Update scipy from 1.7.0 to 1.7.1, Update pandas from 1.3.0 to 1.3.1, Update numpy from 1.20.3 to 1.21.1, Update pydash from 5.0.1 to 5.0.2, Update requests from 2.25.1 to 2.26.0, Update ta-lib from 0.4.20 to 0.4.21
  • [FIX] The ma indicator now better handles volume which is needed for vwap and vwma.
  • [FIX] The kaufmanstop now uses the correct formula for long and now supports the matype parameter.

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

0.22.0

  • [BREAKING CHANGE] For consistency ta.vwmacd now accepts signal_period instead of signalperiod

  • [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 sbkhoshopen in new window and mblumopen in 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-zlobinopen in 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 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,
  • 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 discoheadopen in 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 maebertopen in new window
  • [Improvement] The crossed utility should be a little faster now, as we only use numpy there now.
