NYSE Arca announced the addition of three new options lead market making firms to the NYSE Arca Options platform.

Credit Suisse Securities (USA) LLC, SLK-Hull Derivatives LLC and UBS Securities LLC have all been approved as Lead Market Makers on NYSE Arca’s new options trading platform.

“We are extremely pleased to have these firms joining our exchange as Lead Market Makers,” said Jon Werts, vice president, NYSE Group. “Investors will benefit from their expertise in market making, and the added liquidity and execution quality they bring to NYSE Arca Options.”

SLK-Hull Derivatives began LMM operations on October 10, while Credit Suisse Securities is expected to begin in early November and UBS Securities LLC plans to start by year end. With the addition of these new LMMs, NYSE Arca Options will have 11 lead market makers and a total of 25 market making firms on the system.

The newly-developed system provides automatic executions for customer and broker dealer orders as well as a low cost venue for both lead market makers and market makers to stream quotes from the trading floor or remotely.
