Changelog

The canonical changelog lives in CHANGELOG.md at the repository root. Highlights below.

[Unreleased]

[0.2.5]

Added

  • Zoom-aware candle level-of-detail (LOD): large backtests (6000+ candles) draw a bucket-aggregated, extremes-preserving view that refines as you zoom in, so big charts stay light without losing autoscale accuracy.
  • CandlePatterns (statistical candlestick detector with causal efficacy tracking) and ManualMarks (strategy-driven marks/levels), both free (tier 0).
  • price_source='trade' on TickData.to_klines() / ticks_to_klines().
  • Configurable log-timestamp presentation zone (get_strategy_logger(display_tz=)) and an optional stats_warn= flag on BacktestEngine.run().

Changed

  • tradetropy.io split into focused internal submodules (public API unchanged).
  • bt.plot() defaults to the WebGL backend; show_price_tag now defaults to False.

[0.2.4]

Changed

  • Regenerated the badge logo at higher resolution: a larger icon and more right-side padding on the pill so the "Tradetropy" wordmark no longer crowds the rounded edge (reproducible via tools/gen_logo.py).
  • Plotting: large tick-backtest equity/drawdown curves are min/max decimated for drawing and overlay indicators join the price-panel autoscale for smoother pan/zoom; also fixes an ImportError in bt.plot().

[0.2.3]

Added

  • Interactive documentation demo embedded on the docs landing page and the Examples page, generated from a single canonical snippet (source, stats and chart can never drift from each other).
  • README static chart preview linking to the live interactive chart.
  • Backtesting.py-style P&L panel (sized circle markers, entry-to-exit segment, signed size in the hover tooltip), consistent between backtest and live.
  • New badge-style logo; README badges (Python versions, downloads, license, CI status) and docs landing page download buttons.

Fixed

  • bt.plot() Y-axis autoscale on pan/zoom in backtest, live and replay.

[0.2.2]

Added

  • Horizontal wordmark logo used in the README.

Fixed

  • README logo uses an absolute URL so it renders on PyPI as well as GitHub.

[0.2.1]

Added

  • tradetropy.__version__, resolved via importlib.metadata.

[0.2.0]

Added

  • Bundled sample datasets (tradetropy.datasets) with typed loaders for candles, ticks and a paired L2 order book.
  • MkDocs Material documentation site with an autogenerated API reference.
  • Real optional-dependency extras: mt5, ccxt, bybit, parquet, all, docs.

Fixed

  • drawdown_episodes no longer crashes on a non-unique equity index (produced by multi-symbol backtests).

[0.1.0] - free tier

Initial public release (free tier): BacktestEngine (tick and kline), PoolBacktestEngine, LiveEngine (CCXT Pro and MT5), TrainingEngine; the Strategy framework; the core technical-analysis library; Volume Profile and Rolling Volume Profile; Footprint; Large Trades (L1); market-structure indicators; optimization; statistics; static Bokeh plotting; and data IO for CSV, Parquet and HDF5.

Further features (LiveChart, ReplayEngine, Monte Carlo, Cumulative Delta, Deep Trades and the L2 liquidity suite) unlock progressively through GitHub Sponsors goals - see the canonical changelog.
