Are There Regulatory Differences in Reporting Requirements for Trades Executed via Iceberg Orders versus in Dark Pools?

Yes, the reporting differs based on the venue. An iceberg order, being on a public exchange, has each of its small, executed trades reported to the public tape (e.g. the Consolidated Tape) almost instantly, just like any other trade on that exchange.

For dark pools, the trades are also required to be reported to the tape, but they are often reported with a delay and marked as off-exchange transactions. This distinction allows regulators and the public to differentiate between volume executed on transparent exchanges versus private venues.
