Market-Wide Insider Buy/Sell Ratio History

omnial/get-insider-buy-sell-ratios

One call returns the entire daily history (back to 2003) of market-wide insider buy and sell counts and dollar volume, alongside matching daily S&P 500, DOW, and NASDAQ index values for the same dates -- a single aggregate time series, not data for one company.
