2.0.1

Release Date: 2025-01-12*

  • Fixes
    • Corrected merged candles not combining aggregation factor
    • Fix error when appending a list with one Candle

2.0.0

Release Date: 2024-12-19

  • Non-backward compatible changes:

    • Re-named several Hexital arguments
      • candles_lifespan -> candle_life
      • candlestick_type -> candlestick
    • Re-named several Indicator arguments
      • input_value -> source
      • fullname_override -> name
      • candles_lifespan -> candle_life
      • candlestick_type -> candlestick
      • rounding_value -> rounding
    • Candle's now require a timestamp, a single candle added will use the current UTC time
    • Candle timeframe attribute:
      • Candle's now have a timeframe attribute, this shows the resolution of the Candle, this is optional for Candle's
