Backtest Sanity Checker & Bias Detector

A SaaS tool that analyzes a user's trading script or trade logs to detect lookahead bias, survivorship bias, and calculate the 'Deflated Sharpe Ratio'. It acts as an independent auditor for AI-generated trading strategies before users risk real money.

我們的切入角度
There is a lack of independent 'sanity check' tools that sit between the user's local AI-generated code and full-blown platforms like QuantConnect. Users need a tool that audits their logic for biases and tracks their 'backtest budget' to prevent overfitting.

直接影響該商機判斷的真實 Reddit 評論引用

  • “The painful part is that fixing it properly takes longer than building the strategy in the first place.”
  • “Feels like you’ve found something . .. then a small detail kills it. Happens over and over.”
  • “I’ve also burned hours and hours on QC trying to avoid lookahead issues, corporate action problems, split/dividend handling surprises”
  • “The main risk at this stage is iteration turning into hidden overfitting”
  • “Every iteration where you look at a result, adjust something, and rerun, you're burning through a 'backtest budget.'”
  • “Big part is realising how easy it is to fool yourself with backtests.”
