Backtest Auditor for LLM Trading Code
Build a SaaS tool that independently audits strategy code and backtest logic for common quant errors before users trust performance numbers. The strongest demand is for a domain-specific validator that checks for leakage, unrealistic fills, timestamp issues, and out-of-sample contamination across LLM-generated projects.
これが重要な理由
You build a strategy with an LLM, run the backtest, and the chart looks incredible. Then after days or weeks of excitement, you realize the result depended on a hidden flaw: future leakage, unrealistic fills, broken exits, or data the strategy should never have seen. The hardest part is that your current tools helped create the mistake and then reassured you it was valid. You are left with emotional whiplash and a lot of wasted time. A dedicated auditor matters because generic coding tools can tell you whether code runs, but they do not reliably tell you whether the trading evidence deserves trust.
- · Retail quants and indie algo traders who use LLMs to generate Python or platform-based strategies and need a trusted pre-deployment validation layer.向けに構築。
- · 最も可能性の高い収益化モデル: SaaS subscription。

MVPの範囲 · 1～2週間
- Define the top 15 detectable backtest failure modes and map each to deterministic checks
- Build a file uploader for Python strategy scripts and CSV trade logs
- Implement a parser that extracts signals, entries, exits, and timestamp handling assumptions
- Create a basic report UI with pass, warning, and fail sections
- Add three deterministic audits: lookahead indicators, train-test overlap, and same-bar ambiguity
- Add an isolated rerun service that executes strategy code on held-out sample data
- Implement fill-assumption stress tests with configurable slippage and delay
- Integrate GitHub OAuth and a simple repository import flow
- Generate plain-English remediation notes for each flagged issue
- Launch a landing page with sample audit reports and a paid waitlist

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Advanced users may believe only their custom pipeline is trustworthy and reject a third-party validator.
- 2The product could be seen as superficial if it catches obvious mistakes but misses more nuanced research flaws.
- 3Framework fragmentation across Python, MT5 exports, and proprietary scripts could make the initial integration burden too high.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
This was the clearest repeated need in the discussion. Around a dozen comments centered on the danger of letting one system both build and evaluate a strategy, and several participants described separate validators, second-model audits, or isolated code paths as the only way to trust results. Multiple users also listed concrete error classes such as leakage, survivorship, timestamp misalignment, and unrealistic execution assumptions, which gives the product a specific feature roadmap.
