Stop Using Vision LLMs to Read Trading Charts — 4 Models, 2 Vendors, 40 Real Signals: 51% Direction, 1/215 Patterns, 100% Long-Bias on Gemini

Stop Using Vision LLMs to Read Trading Charts — 4 Models, 2 Vendors, 40 Real Signals: 51% Direction, 1/215 Patterns, 100% Long-Bias on Gemini

A deep empirical audit of using frontier vision LLMs as chart-pattern experts in a production crypto signal pipeline. Tested against QuantAgent (arXiv:2509.09995), the paper repeatedly cited as proof that LLM agents can trade from candlesticks.

Conducted April 2026. Every model called, every call logged, every fixture tied to a verified trade outcome. Four frontier models, two vendors (Anthropic, Google), 215 LLM calls, $1.16 total spent.

From the team building signals.x70.ai — a production AI-powered crypto signals service. Open-source companion: roman-rr/trading-skills.

Formal preprint. A peer-review-format PDF version of this audit is published as a preprint:

MemPalace Exposed: 42,000 Purchased Stars, Zero Innovation — It's ChromaDB With a Celebrity Name

A deep technical audit of MemPalace (github.com/MemPalace/mempalace) — what it claims vs what it actually is.

Every source file read. Every benchmark traced. Every MCP tool verified. Compared against Mem0, Zep/Graphiti, and Letta/MemGPT. GitHub stargazer timestamps analyzed for bot patterns.
