Build, backtest and validate quantitative trading agents in plain English
Describe a trading thesis and the AI drafts a fully wired quantitative model with 71 building blocks, 25 signals and 16 curated templates — zero lines of code required.
A NautilusTrader engine models fees, slippage, spreads and funding across 14 venues, with single-asset, multi-asset, parameter-sweep, walk-forward and crisis-period modes.
Walk-forward analysis separates durable logic from historical coincidence, and crisis replay stresses strategies against regimes such as March 2020 and May 2022.
A cross-session brain tracks market regime, performance drift and parameter sensitivity so the model stays observable and continuously reviewed.
