You are now able to review all option trades across all major exchanges in real-time and filter them based on spread, trade size and option volume. You are also able to drill down to specific securities (ie. AMZN, AAPL, BABA, SPY etc.)
Today we are introducing a new way for you to filter unusual option activity: by bid & ask spread. You can update an existing notification or create a new one dedicated to just filtering for spread by going to your alerts tab.
You may now also order trades when looking at individual equities based on the bid and ask spread. To do so just click the ‘spread’ header at the top of the trades log to order in ascending or descending order.
Millions of options trades exchange hands every day. Not all of them are made equally, that’s for sure. Some carry more information than others. Unusual option trades are that type of option trade.
Unusual option activity is defined as a single trade that is bought on the ask or sold on the bid, with unusual volume and/or trade size compared to the open interest for that particular strike and expiry. This means that these are new contracts being traded, expressing a fresh opinion on the underlying.
Why is this interesting? Well given a large enough trade and it being bought…
