TradeLens Toolkit Diagnoses Whether AI Trading Agents Pay for Their Own Intelligence

Jul 14, 2026

A new arXiv paper introduces TradeLens, a diagnostic toolkit that evaluates whether LLM-based trading agents convert their reasoning costs into measurable profit. The study finds that viability depends on intelligence-to-profit conversion, with models like DeepSeek-V3.2 and GLM-4.7 showing different failure patterns. Capital scale, trading frequency, and architecture amplify or degrade decision-attributed timing value but do not determine viability.

Why it matters: This work reframes evaluation of LLM trading agents from performance ranking to trace-grounded diagnosis of cost-effectiveness, which is critical for practical deployment.
