STO (Super Trading Online) provides online trading services to retail clients through popular platforms like MetaTrader 4 and MetaTrader 5. The company focuses on offering leveraged trading via CFDs across various financial markets. Historically, the STO brand was operated by entities regulated in the UK (FCA) and Cyprus (CySEC). However, these entities faced insolvency and license withdrawal in 2019. The brand currently appears to be operated by an offshore entity, STO Ltd, registered in St. Vincent and the Grenadines.
