The option flow orders on the InsiderFinance dashboard are single-leg orders filled at or above ask/offer, meaning the dashboard only shows buy orders.

Smart money order flow for ask activity (i.e. the "purchasing side") is a very powerful leading indicator, and our proprietary filtering algorithm only shows orders where the trader’s intent is clear.

In other words, call orders imply bullish intent, and put orders imply bearish intent.  

There’s no way to tell if an order executed at mid-market was bought or sold, so InsiderFinance does not track orders executed at mid.

InsiderFinance doesn’t currently show orders filled at or below bid, but those orders will be added soon.
