GREAT NEWS! Nadex has a new market maker. This company is independent of IG Group so this further adds to the credibility factor of Nadex as an exchange.
Group One and its affiliates form one of the largest, privately held options trading firms in the United States. So perfect for a market maker on Nadex icon smile Forums
They just launched and will be mainly providing liquidity on indices and commodities. More market makers are coming on that will also provide more on Forex.
Obviously liquidity attracts liquidity (hence good reason for multiple market makers on one exchange). Tighter bid ask spreads and more contracts attracts traders - more traders attracts more market makers and the cycle goes on.
