Returns FINRA daily short volume data for securities, reported by individual market centers and reporting facilities. ## Data Coverage This endpoint provides **off-exchange activity** data aggregated from FINRA's Short Sale Volume files. The data represents short selling activity reported by market centers and third-party reporting facilities, including both exchange and off-exchange venues. ## Use as Market Proxy Short volume data can serve as a meaningful proxy for overall market sentiment and activity: - **Market Structure Insight**: Tracks short selling intensity across different trading venues and market centers - **Liquidity Indicator**: Higher short volume often correlates with increased market activity and liquidity - **Sentiment Analysis**: Can indicate bearish positioning, though short volume alone doesn't determine market direction - **Cross-Venue Analysis**: Compare short volume patterns across different reporting facilities to understand how activity varies by venue type ## Data Characteristics - Data is reported at the facility level for granular analysis - Use the `/securities/daily_short_volume/consolidated` endpoint for a single aggregated view across all facilities - Short exempt volume reflects pre-borrow arrangements and other regulated short selling exemptions - Each data point represents a full trading day's accumulated short volume
