NOTICE: Alerts are NOT buy signals. Alerts point to options contracts that are experiencing unusual activity and breaking certain thresholds. Please utilize the many features on the platform to analyze a stock and options contract before placing a trade.

Filter toggle - Filter data to show only the options trades that meet your criteria: puts; calls; different flow types; trades executed on the bid and/or ask; options price; large contract size or trade notional value; weekly expirations; market sectors; and/or security type. Check the items you wish to see.

The Unusual Activity filter identifies activity in stocks that rarely see options activity. This filter will override other filters when it is checked so only unusual activity will be displayed. Uncheck this filter to re-enable the other filters.

Ask and Above Ask filters are enabled by default to specify directionally bullish calls or bearish puts.

Heat Map tab

The Heat Map is a graphic representation of the day’s options flow on the Flow Tab. The Heat Map shows the frequency of flow centered around the contract strike price nearest the current price in yellow. Calls (C) are on the left and puts (P) are on the right.

- C1 and P1 columns include all contracts expiring the following week

- C2 and P2 columns include all contracts expiring in 2 weeks or more

- Green shading - indicates Bullish Flow (Calls traded on the Ask and Puts traded on the Bid). Cells with the darkest shading indicate areas of the highest trade activity

- Red shading - indicates Bearish Flow (Call traded on the Bid and Puts traded on the Ask)
