Running Autonomous AI Agents with Curupira

How Curupira orchestrates autonomous AI trading agents — from research to execution. Architecture overview, agent lifecycle, monitoring, and how to build your own agent on the platform.

 Markets Are Languages, Not Physics
AI Trading

Markets Are Languages, Not Physics

Why treating financial markets as natural language problems — not physics problems — yields better predictive models. The theoretical framework behind our AI trading approach, inspired by Renaissance Technologies and modern NLP.

Quant Research

31 Strategies Tested, 4 Survived

The complete results of testing 31 systematic trading strategies across forex and crypto. What worked, what failed, and the patterns that separate robust strategies from curve-fitted illusions.

 Hurst Exponents for Detecting Mean Reversion in Forex
Quant Research

Hurst Exponents for Detecting Mean Reversion in Forex

Using the Hurst exponent to dynamically identify mean-reverting vs. trending regimes in forex markets. Complete theory, Python implementation, and backtest results for a regime-adaptive trading system.

 FVG Magnetism: Do Fair Value Gaps Really Fill?
Quant Research

FVG Magnetism: Do Fair Value Gaps Really Fill?

A rigorous statistical analysis of fair value gap magnetism in price action trading. We test the claim that FVGs act as magnets for price, introduce the FVG Wall specification, and present backtest results across forex and crypto markets.

 Entropy Collapse as a Volatility Timing Signal
Quant Research

Entropy Collapse as a Volatility Timing Signal

How we use Shannon entropy of price returns to detect volatility regime changes before they happen. Full methodology, Python implementation, and backtest results showing a 1.44 profit factor on EURUSD.

The Graveyard

Most quant teams only show winners. Here's the full list.

dead FVG Magnetism OHLC inflated 4×. Tick PF 1.04 → not tradeable.
dead Jump Fade (Forex) 50-51% WR at all thresholds. Zero edge.
dead Hurst Regime (Crypto) H>0.6 fires 100% of bars. Not a filter.
dead ECVT (Equities) 0-9 signals in 2 years. Forex-specific.
dead Biology Flocking Needs 30+ stock basket. Not applicable.
alive ECVT (EURUSD 1H) PF 1.44, +198 bps OOS. Walk-forward validated.
alive Jump Trend (1:1) 55% WR, +293 pips. Component decomposition win.
