Could you build this?
Partial The evaluation harness UI, scoring dashboards, and basic backtesting harness can be vibe-coded, but building leak-proof point-in-time financial simulation environments with low-latency market feeds and historical consensus benchmarks requires specialized financial engineering.
What it would actually take: A production version requires an event-driven architecture (Python/Rust, ClickHouse or TimescaleDB) providing strict point-in-time execution environments that prevent future data leakage across complex financial disclosures, earnings transcripts, and market data. The hard part is acquiring and normalizing expensive historical financial data feeds (Bloomberg, FactSet, SEC EDGAR) and building a deterministic deterministic runtime that accurately handles corporate actions, restatements, and market impact. It demands quantitative financial domain expertise, high-integrity data infrastructure, and specialized eval benchmarking design.
