RGM Advisors LLC and Allston Trading LLC are discussing future merger plans. Their merger will append both companies' automated trading on futures markets, said the Wall Street Journal on Tuesday.

The high-frequency trading firms are major clients of the New York Stock Exchange and futures platforms under the CME Group operations.  A merger would extend the continuous tie-ups when electronic traders are now considering giving in to rivals posting better figures, said the journal.

RGM Advisors, based in Austin, Texas, performs trades in multiple asset classes globally. On the other hand, Allston Trading, based in Chicago, Illinois, perform financial exchangers in 20 countries.

Allston Trading Chief Executive Officer Raj Mahajan said that "From time to time, as interesting partnership opportunities emerge or as we identify acquisition opportunities, Allston management will of course consider them if they accelerate our growth objectives but will not comment on any of those discussions unless there is something concrete to communicate."
