Exhibit (a)(5)(F)

Monex Group Commences Tender Offer for All Outstanding Shares of Common Stock of TradeStation Group, Inc.
TOKYO, May 11, 2011 - Monex Group, Inc. (“Monex”: TSE Code 8698 TSE 1st section, Oki Matsumoto Representative Director, Chairman and CEO) announced the commencement of a tender offer, through its wholly-owned subsidiary in the United States, Felix 2011 Acquisition Sub, Inc. (the “Acquisition Subsidiary”), for all outstanding shares of common stock of TradeStation Group, Inc. (NASDAQ: TRAD, hereinafter “TradeStation”), for $9.75 per share, net to the seller in cash, without interest and less any required withholding taxes, on May 10, 2011 (EDT).
The tender offer is being made pursuant to an Agreement and Plan of Merger among Monex, the Acquisition Subsidiary and TradeStation, which Monex announced on April 21, 2011 in the press release titled “Monex Group to Acquire TradeStation Group, Inc., a leading US online brokerage firm, Through A Friendly Cash Tender Offer”. The offer currently is scheduled to expire at 12:00 midnight, New York City time, on Tuesday, June 7, 2011. The Acquisition Subsidiary may extend the offer. If the offer is extended, the Acquisition Subsidiary and Monex will inform the depositary for the offer and will make a public announcement of the extension not later than 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.
Following the consummation of the tender offer, if the Acquisition Subsidiary acquires a majority, but less than 80%, of the total outstanding shares of common stock of TradeStation through the tender offer, the Acquisition Subsidiary has an option to purchase from TradeStation, at a price per share equal to the offer price paid in the tender offer, up to a number of newly issued shares of common stock of TradeStation that would, together with the shares acquired in the tender offer, constitute one share more than 80% of the outstanding shares of common stock of TradeStation on a fully diluted basis, but not less than one share more than 80% of the outstanding shares on a non-fully diluted basis (the “Top-Up Option”). In the event that Monex directly or indirectly owns at least 80% of the outstanding shares of common stock of TradeStation after completion of the tender offer, any exercise of the Top-Up Option and any other acquisition of shares, TradeStation and the Acquisition Subsidiary will merge without a meeting of TradeStation’s shareholders. In the event the tender offer is consummated, but the Acquisition Subsidiary has not acquired at least 80% of the outstanding shares of TradeStation common stock in the tender offer, through the exercise of the Top-Up Option or otherwise, then TradeStation will hold a shareholders’ meeting to approve the merger and the other transactions contemplated by the Agreement and Plan of Merger. Following the merger, TradeStation will become a wholly-owned subsidiary of Monex.
