Volume data may be incomplete

Our short volume data are sourced from various exchanges (CBOE, NYSE, and NASDAQ) as well as FINRA.

Short volumes are important because they can give a trader insight into the trading strategies of various market participants including short sellers. Short sellers don't trade in a vacuum, and they leave traces behind them. The aggregate short volumes give us clues that can aid our decision making process.
