"Aggregated Trades" feature breakdown
The "aggregated trades" switch offers an alternative view of the flow feed.
When looking at the flow feed each line of data represents one transaction filled at one of the many options exchanges. The "Aggregated Trades" toggle, located near the bottom of the filters, groups transactions that are likely from the same trade into a singular line of data. This can make your filtering efforts more effective.
Transactions that have been aggregated are shaded in the feed and are accompanied by
A singular trade may be made up of multiple transactions (e.g. a trade of 1,000 size being filled for 500 contracts made up of multiple transactions (e.g. a trade of 1,000 size being filled for 500 contracts by one exchange, 499 by another, and 1 by the last for a total of 1,000 total contracts would take up three lines of data).
Using the example of the singular trade made up of multiple transactions from above.. assume each of the 1,000 contracts was $1.01 per. The aggregated value of the trade would be $101,000. This aggregated trade would show up when filtering the flow feed for a minimum premium of $100,000. Without aggregation, however, neither the 500 nor the 499 sized trades would show up with this > $100,000 filter.
Here's a real world example: RGTI 20c 8/15/2025. An aggregated total of 1,820 contracts, totaling $783K premium can be seen in the feed.
As mentioned earlier selecting the icon will let you view the individual executions. In this instance the 1,820 contracts were executed across multiple exchanges. You can see fills ranging from 13 contracts to 196. Premiums for each fill range from $6k to $84k.
