STOR (Suspicious transaction and order report)
A STOR reports suspected market abuse, such as insider dealing or market manipulation, in orders or transactions. The term comes from the EU and UK market-abuse regimes, where firms arranging or executing transactions must report suspicious orders as well as executed trades. It is separate from the money-laundering STR and goes to the market regulator rather than the FIU.
Why it matters for brokers and payment firms
Brokers with EU, UK or similar licences may need both: an STR for laundering suspicions and a STOR for manipulation. Surveillance that looks at orders, not only fills, is what makes a STOR possible.
