IB look set to move their London office, eliminating the PDT rule for UK and EU clients. See link for full details but from FAQ, Q: Will I be subject to the U.S. Pattern Day Trading Rule once my account is migrated? A: Accounts maintained with IBUK are subject to the U.S. Pattern Day Trading (PDT) rule as the accounts are introduced to and carried by IBL, a U.S. broker. The PDT rule restricts accounts with equity below USD 25,000 to no more than 3 Day Trades within any 5-business day period. As accounts migrated to IBLUX, IBIE or IBCE will not be introduced to IBL, they will not be subject to the PDT rule. But FAQ also say.. Q: What happens if IBKR does not receive the regulatory approval necessary to migrate accounts by December 31, 2020? A: IBLUX, while approved, it is subject to constraints on the permitted scale of its business and licensing for either IBIE or IBCE is therefore necessary to complete the migration prior to December 31, 2020. If a determination is made that neither will receive licensing in time, clients will be contacted with an explanation as to how their account will be treated at the end of the Brexit transition period.
