screen_markets
ActiveTool of SimpleFunctions
declared in 1.0.0
Indicator-based market screener. The middle layer between raw price scan and LLM thesis edges. Filters the universe by cheap math labels — no LLM round-trip required for the screening pass itself. Indicators: IY (implied annualized yield %), CRI (cliff risk = max(p,1-p)/min(p,1-p)), OR (event overround / arb), EE (expected edge in cents from thesis or regime), LAS (liquidity-adjusted spread), τ (days to expiry). Null is signal: no_thesis=true / no_orderbook=true are POSITIVE selectors for unloved markets — strategy 2/3 long-tail entry condition. Free-tier and rate-limited; API keys unlock higher limits.
