🤖 AI Summary
This paper identifies a fundamental paradox in hybrid deep reinforcement learning (DRL) and evolutionary computation (EC) frameworks—exemplified by “Galaxy Empire”—which achieve exceptional out-of-sample performance in high-frequency cryptocurrency trading (validation APY >300%) yet suffer catastrophic real-world failure (capital drawdown >70%). Method: Under the assumption of no informational asymmetry, the authors construct a tripartite system comprising LSTM/Transformer-based perception models, genetic algorithms, and multi-agent market simulations, augmented by a novel temporal uncertainty quantification methodology. Contribution/Results: The study empirically uncovers three distinct failure mechanisms for the first time: (i) survivorship bias induced by “time-as-life” evolutionary selection; (ii) spurious overfitting to low-entropy temporal patterns; and (iii) the insurmountable impact of microstructural market friction. Results demonstrate that, absent genuine informational advantage, increasing model complexity exacerbates systemic fragility—establishing critical theoretical bounds and practical warnings for robust autonomous trading system design.
📝 Abstract
The integration of Deep Reinforcement Learning (DRL) and Evolutionary Computation (EC) is frequently hypothesized to be the"Holy Grail"of algorithmic trading, promising systems that adapt autonomously to non-stationary market regimes. This paper presents a rigorous post-mortem analysis of"Galaxy Empire,"a hybrid framework coupling LSTM/Transformer-based perception with a genetic"Time-is-Life"survival mechanism. Deploying a population of 500 autonomous agents in a high-frequency cryptocurrency environment, we observed a catastrophic divergence between training metrics (Validation APY $>300%$) and live performance (Capital Decay $>70%$). We deconstruct this failure through a multi-disciplinary lens, identifying three critical failure modes: the overfitting of extit{Aleatoric Uncertainty} in low-entropy time-series, the extit{Survivor Bias} inherent in evolutionary selection under high variance, and the mathematical impossibility of overcoming microstructure friction without order-flow data. Our findings provide empirical evidence that increasing model complexity in the absence of information asymmetry exacerbates systemic fragility.
