Thinchain

Pulls options chains from Tradier (and Polygon), strips out bad ticks and ghost quotes, then compresses 500 row payloads down to the 20 strikes that matter for your strategy. The sanitization layer clamps deltas, flags illiquid strikes, and kills inverted spreads. Circuit breaker logic refuses to serve data when more than 65% of rows look suspicious. You get three tools: get_compressed_chain for iron condors or straddles with 95% token savings, get_sanitized_quote for single symbols, and get_circuit_status to check data quality before you trade. Extracted from a production trading app, so the edge cases are already handled.
