The Red Queen's Trap: Limits of Deep Evolution in High-Frequency Trading

Yijia Chen

TL;DR

Addresses whether DRL-EC hybrids can sustain alpha in non-stationary, high-frequency markets. The study deploys 500 agents with LSTM/Transformer perception and a Time-is-Life evolutionary loop in a live crypto environment, followed by a rigorous autopsy to diagnose failures. It identifies three failure modes—overfitting to aleatoric uncertainty in low-entropy data, survivor bias from selection under high variance, and unavoidable microstructure friction without order-flow data—leading to capital decay despite favorable training signals. The results argue that increasing architectural complexity cannot compensate for fundamental information asymmetry and market frictions, offering sobering lessons for retail participants. Collectively, the work provides empirical support for market efficiency at high frequencies and cautions against overreliance on AI-driven, fully autonomous trading ecosystems.

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 \textit{Aleatoric Uncertainty} in low-entropy time-series, the \textit{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.

  • Figure 3: Systemic Insolvency Snapshot at T+4h. The dashboard reveals a catastrophic divergence: while the pie chart shows a diverse population of "living" agents (Equity $\approx \$100$), the central ledger (Group Cash) reflects a deficit of $-\$338,427$. This visualizes the "Soft Budget Constraint" where the system effectively prints money to sustain zombie agents.
