Good to know

• FINRA publishes short interest about a week after each settlement date and keeps one rolling year. Daily short volume appears the evening of each trading day.
• Daily short volume covers trades reported to FINRA's facilities, not every exchange's own trades, so shortRatio is the share of that volume.
• Figures are as FINRA publishes them. Need another field or market? Contact tacps126@gmail.com.
