Charting tools and strategy builders help you make a backtest. None of them tell you the backtest is a lie. Phantom Auditor takes your finished results — from any tool — and runs the same overfit battery and phantom-PnL detectors our own trading desk uses to kill fake edges.
The build-and-chart tools cluster at the top; the integrity layer (bottom three rows) is empty for everyone but us.

No competitor sells a dedicated, market-aware, ledger-in backtest-integrity auditor. The closest things that exist are academic demos (LBNL's overfit tool), open-source libraries (mlfinlab), and DSR shown as a single number inside a walled platform. TrendSpider and EdgeBuild are chart-and-build tools; TradingView-MCP just makes chart data legible to an agent. Phantom Auditor is adversarial, not descriptive — it takes results from any tool and returns a per-market verdict, and it is prediction-market native (kalshi/polymarket phantom classes nobody else models). QuantConnect/LEAN is the most serious build-and-backtest platform in the group (free unlimited cloud backtesting, LEAN engine free open-source locally) — but overfit awareness there is a single PSR number on your own backtest inside their platform: it does not audit results produced anywhere else, and it has no prediction-market venue data.
