Earlier on Tuesday, the regulator slapped the listed broker with a PLN 9.9 million ($2.7 million) fine for “irregularities in the execution of client orders,” the KNF explains.
XTB said it fully maintains “its previous position” and finds no grounds for “objections regarding the company's operations”
XTB stressed shortly after the launch of the regulatory investigations in 2017 that it applies an execution model that passes on the full benefit of price improvements to its clients. The brokerage described the infringements alleged by the KNF as “unfounded”.
