Engineering notes from the AutoQuant team. Validation methodology, AI strategy generation, and the architectural choices behind local-first algorithmic trading.https://autoquant.ai/https://autoquant.ai/blog/a-chart-copilot-that-cannot-make-up-a-price/https://autoquant.ai/blog/a-chart-copilot-that-cannot-make-up-a-price/AutoQuant v0.9.12 ships Chart Copilot: ask for support and resistance and the chart draws itself. The LLM never touches a number. This is the architecture, and the two bugs we caught live that prove why prompt discipline is not enough.Mon, 20 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/lookahead-bias-in-backtesting/https://autoquant.ai/blog/lookahead-bias-in-backtesting/Lookahead bias is when a backtest uses information that was not available at trade time. It is the most common reason strategies look brilliant in testing and die in live trading. Here is how it sneaks into real code, how to detect it, and how to make it unwritable.Mon, 20 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/how-we-stopped-our-ai-from-making-up-option-strikes/https://autoquant.ai/blog/how-we-stopped-our-ai-from-making-up-option-strikes/AutoQuant v0.9.11 publishes swing trade ideas every weekday before the open, with real option strikes picked from the live chain. The hard part was not generating ideas. It was making sure the AI never invents a number. This is the architecture, and the bug that proved it.Sun, 19 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/one-line-of-pandas-and-why-we-built-a-language/https://autoquant.ai/blog/one-line-of-pandas-and-why-we-built-a-language/A single line of handwritten pandas in our scanner silently turned enter-once-on-the-signal into enter-every-bar, and it flattered the backtest before we caught it. That bug is why PRIOR exists: a small open-source language for trading strategies where a whole class of backtest lies cannot be written.Thu, 09 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/we-built-a-market-scanner-in-a-weekend/https://autoquant.ai/blog/we-built-a-market-scanner-in-a-weekend/AutoQuant v0.4.0 ships StratScanner, a scanner that watches a universe of stocks, fires the moment a condition is met, and hands you a backtestable strategy on the spot. On Saturday it flagged four names sitting at their lower Bollinger bands. We backtested one of them live.Sun, 05 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/the-backtest-killer-nobody-talks-about-human-leakage/https://autoquant.ai/blog/the-backtest-killer-nobody-talks-about-human-leakage/Every retail trader learns about look-ahead bias, survivorship bias, and overfitting. There's one more bias that contaminates strategies passing every standard robustness check, and it lives in your head, not your code.Sat, 04 Jul 2026 00:00:00 GMThttps://autoquant.ai/blog/why-autoquant-runs-on-your-machine/https://autoquant.ai/blog/why-autoquant-runs-on-your-machine/AutoQuant is a desktop app, not a cloud platform. Your strategies live on your disk, your backtests run on your CPU, your AI Loop calls hit your API keys directly. Here's what local-first means in practice.Mon, 22 Jun 2026 00:00:00 GMT
