The lawsuit was resolved after Ninja admitted that its trading screen, NinjaTrader SuperDOM, had infringed two of Trading Technologies’ (TT) patents awarded to its MD Trader platform.

Under the terms of the agreement, Ninja will pay TT a variable royalty of at least 10 cents per side for all contracts that trade in conjunction with the NinjaTrader SuperDOM. It will also extend connectivity support for its advanced order management platform to TT’s ultra-high speed gateways.

In return, TT has agreed to absolve Ninja and its customers of any past liability for infringement of its patents.

Ninja is the latest vendor to be taken to court by TT over patent infringement. Last year the firm sued brokers Kingstree Trading and Goldenberg Hehmeyer, and the UK’s Patsystems and futures commission merchant Advantage Futures settled claims recently.
