===Commodity Futures Trading Commission (CFTC) action===

On September 28, 2021, the U.S. [[Commodity Futures Trading Commission]] (CFTC) issued a press release announcing that it had settled charges against Interactive Brokers, LLC. The settlement included a $1.75 million fine and $82.57 million in customer restitution for the following violation:<ref>https://www.cftc.gov/PressRoom/PressReleases/8432-21</ref><blockquote>Failing to diligently supervise the handling of its customer accounts by not adequately preparing and configuring its electronic trading system to receive negative prices and calculate margin on April 20, 2020, in violation of CFTC Regulation 166.3.</blockquote>On April 20, 2020, the May 2020 West Texas Intermediate (WTI) crude oil futures contract, traded on the NYMEX exchange, settled at negative prices. The CFTC alleges that when a futures commission merchant, such as Interactive Brokers, LLC, operates systems incapable of accurately reflecting actual market prices, customers may suffer harm.

It remains unclear whether the CFTC or any other regulator has required Interactive Brokers, LLC, to update its systems to a specific performance standard to prevent customers from being exposed to potential harm from similar incidents in the future.
