IB est tellement professionnel, mécanisé dans ses automatismes et prudentiel, que quand des malversations et manquements sont commis ils finissent par s'en apercevoir eux même et se dénoncer comme des grands aux autorités de régulation

On est en présence d'un fonctionnement assez exemplaire

CFTC Orders Connecticut-based Interactive Brokers LLC, a Registered Futures Commission Merchant, to Pay a $225,000 Civil Monetary Penalty
Firm failed to supervise its employees, failed to maintain sufficient U.S. dollars in customer segregated accounts, and failed to compute on a currency-by-currency basis the amount of customer funds on deposit and required to be on deposit in segregated accounts
...
Specifically, the CFTC Order finds that from at least January 2008 through at least April 4, 2011, IB failed to compute as of the close of business each day, on a currency-by-currency basis, the amount of customer funds required to be on deposit and the amount of customer funds actually on deposit in segregated accounts on behalf of commodity and options customers.
...
The Order also finds that prior to May 9, 2012, IB did not have adequate procedures in place and failed to adequately train and diligently supervise its officers, employees, and agents to prevent the violations described in the Order. However, the Order finds that IB independently implemented corrective measures after discovering the violations and cooperated with the CFTC’s Division of Enforcement in investigating the circumstances.
