How to Find Unusual Options Activity in TrendSpider

The TrendSpider platform is currently able to track two types of Unusual Options trades: Sweep and Block trades.

  • A sweep is defined as a series of trades that hit the tape within 250 milliseconds of each other where at least 75% of the trades are at the bid or the ask and the total premium paid for the contracts exceeds 20 thousand dollars in premium.
  • A block is defined as a single options trade over 20 thousand dollars in premium that occurred at the bid or ask.

Users can choose the unfiltered view to help develop a bias and then filter by Expiry Date, Premium, and Strike Price to hone their specific trade.

For an in-depth view on how to use the tool, as well as some examples of how price reacts when Unusual Options orders hit the tape, please watch the video below!
