Subject: [PATCH] feat: VBT visualization + validation pipeline, HFT tick viz,
DuckDB loader
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Track 1 — VBT Candle-Frequency Pipeline:
- backtests/vbt_validator.py: VBTValidator with 11 checks — timestamp monotonicity,
duplicates, NaN, data gaps, lookahead bias, signal alignment, density,
coincident entry/exit, min trade count, fee application, benchmark comparison.
ValidationReport dataclass with errors/warnings/stats. Validates VBT results
or raw signal arrays.
- backtests/vbt_viz.py: VBTVisualizer with 10+ Plotly chart methods — equity
curve with benchmark, drawdown, rolling Sharpe/Sortino/vol, trade markers,
returns distribution with normal fit, monthly PnL heatmap, gross vs net,
holding periods, parameter sensitivity heatmaps, dashboard compositor,
HTML save (self-contained, CDN Plotly). All methods handle empty/null inputs.
- backtests/vbt_report.py: Markdown + HTML report generator — structured
sections for implementation summary, performance metrics, cost analysis,
validation results, signal analysis, known limitations, next steps.
batch_report() for mass report generation from results directory.
- backtests/vbt_runner.py: Added run_benchmark() (buy-and-hold VBT portfolio),
validate() (integrated VBTValidator), run_with_report() (fetch→validate→
backtest→visualize→save in one call).
Track 2 — HFT Tick Pipeline:
- backtests/tick_viz.py: 9-panel HFT dashboard — price+trade markers,
spread dynamics, top-of-book depth, microprice vs mid, OBI/OFI panel,
VPIN toxicity with thresholds, event timeline (PnL from tick_runner),
markout curves at 6 horizons. Parquet→pandas→Plotly pipeline.
Dark-themed HTML output for microstructure review.
- data/duckdb_load.py: Parquet→DuckDB loader — creates l2_snapshots,
trades, funding tables with schema. Pre-computed 1s rollup views for
microprice, OFI, trade imbalance. Markout queries directly in SQL.
Incremental loading with load_state tracking.
CLI Integration:
- cli.py: Added 'report' (full VBT report), 'validate' (check existing
results), 'hft' (tick dashboard generation) commands. Fixed argparse
help string escaping.
355 tests passing (34 new).

+"""
+HFT Tick Visualization Dashboard — Plotly-based microstructural charts.
+
+Visualizes tick-level order book data, trades, and microstructural
+metrics from DuckDB (or Parquet directly for small datasets).
+
+Panels:
+ 1. Price + Trade Markers (candlestick with buy/sell markers)
+ 2. Bid/Ask Spread Dynamics (spread bps over time)
+ 3. Top-of-Book Depth (bid size vs ask size stacked area)
+ 4. Microprice vs Mid (two lines with deviation fill)
+ 5. Order Flow Imbalance (OBI/OFI panel)
+ 6. VPIN Toxicity (with threshold bands)
+ 7. Inventory + PnL (from simulation results)
+ 8. Markout Analysis (buy vs sell markout curves)
+ 9. Event Timeline (fills, cancels, re-quotes)
+
+Usage:
+ python -m backtests.tick_viz --coin BTC --start 2026-08-01 --end 2026-08-02
+ python -m backtests.tick_viz --db data/normalized/ftdt_tick.db --dashboard
