Item 3.

Source and Amount of Funds or Other Consideration

Monex, Purchaser and TradeStation entered into an Agreement and Plan of Merger, dated as of April 20, 2011 (the “Merger Agreement”), a copy of which is filed herewith as Exhibit 1 and incorporated herein by reference. Pursuant to the Merger Agreement, on May 10, 2011, Purchaser commenced a tender offer (the “Offer”) to purchase all of the outstanding Shares, at a purchase price of $9.75 per Share, in cash, net to the seller, without interest and subject to any required withholding taxes (the “Offer Price”), upon the terms and subject to the conditions set forth in an offer to purchase dated May 10, 2011 (as amended or supplemented from time to time, the “Offer to Purchase”), a copy of which was included as Exhibit (a)(1)(A) to the Tender Offer Statement on Schedule TO filed by Purchaser with the U.S. Securities and Exchange Commission (the “SEC”) on May 10, 2011 (as amended or supplemented from time to time, the “Schedule TO”), and the related letter of transmittal (as amended or supplemented from time to time, the “Letter of Transmittal”), a copy of which was included as Exhibit (a)(1)(B) to the Schedule TO.

The Offer expired at 12:00 midnight, New York City time, on Tuesday, June 7, 2011, at which time, based on information from American Stock Transfer & Trust Company, LLC, the depositary for the Offer, TradeStation’s shareholders had validly tendered and not withdrawn 32,238,029 Shares (including Shares tendered pursuant to the guaranteed delivery procedures), which represented approximately 74.3% of the outstanding Shares on a fully diluted basis, and 80.3% of the then outstanding Shares on a non-fully diluted basis, and therefore satisfied the “minimum tender condition” of the Offer (which required the tender of a majority of TradeStation’s outstanding Shares on a fully diluted basis). Purchaser accepted for payment all validly tendered Shares. Based on the Offer Price and the number of Shares validly tendered and accepted for payment (including Shares tendered by notice of guaranteed delivery), at the expiration of the Offer, the value of the Shares accepted for payment by Purchaser pursuant to the Offer was approximately $314.3 million. The funds used to purchase the Shares were provided by Monex to Purchaser as further described below.

On June 8, 2011, subsequent to the expiration of the Offer and pursuant to the Merger Agreement, Purchaser exercised its option (the “Top-Up Option”) to purchase directly from TradeStation on June 10, 2011, 12,369,184 newly-issued Shares (the “Top-Up Shares”) at the Offer Price per Share in exchange for $123,691.84 in cash, representing the aggregate par value of the Top-Up Shares, and a promissory note issued by Purchaser to TradeStation in the aggregate principal amount of $120,475,852.16. The Top-Up Shares were issued pursuant to the exemption from registration requirements provided by Section 4(2) of the Securities Act of 1933, as amended.

On June 10, 2011, Monex completed the acquisition of TradeStation through a short-form merger (the “Merger”) in accordance with Section 607.1104 of the Florida Business Corporation Act (the “FBCA”). In the Merger, Purchaser was merged with and into TradeStation with TradeStation continuing as the surviving corporation and a wholly-owned subsidiary of Monex

Page 6 of 10

(the “Surviving Corporation”). At the effective time of the Merger, each Share then outstanding (other than any Shares in respect of which appraisal rights are validly exercised under the FBCA and any Shares owned by TradeStation, Monex or any of their subsidiaries (including Purchaser, but other than Shares in trust accounts, managed accounts and the like, or otherwise held in a fiduciary or agency capacity for the benefit of customers or clients, or shares held in satisfaction of a debt previously contracted, if any)) was, by virtue of the Merger and without any action on the part of the holders of the Shares, converted into the right to receive the Offer Price in cash, without interest and subject to any required withholding taxes. The net transaction value of the Offer and the Merger was approximately $402 million, which includes the aggregate consideration to cash out certain employee stock options and other stock-based compensation of TradeStation.

Monex has provided or will provide Purchaser with sufficient funds paid or to be paid in connection with the Offer and the Merger. As described in the Offer to Purchase, Monex received commitment letters from Shinsei Bank, Limited and Mizuho Corporate Bank, Ltd. to loan, in the aggregate, the equivalent of approximately $247.1 million in connection with the Offer and the Merger, copies of which are field herewith as Exhibit 2 and Exhibit 3, respectively, and incorporated herein by reference. Monex subsequently entered into a loan agreement with each of Shinsei Bank, Limited and Mizuho Corporate Bank, Ltd., consistent with the terms and conditions set forth in the commitment letters with such lenders. All information contained in “Section 10 — Source and Amount of Funds” of the Offer to Purchase is incorporated herein by reference.

All Shares that were validly tendered and not properly withdrawn were accepted for purchase by Purchaser on June 8, 2011.

Upon the purchase of Shares pursuant to the Offer, in accordance with the terms of the Merger Agreement, TradeStation increased the size of its board of directors from five to nine members, one existing director of TradeStation, Nathan D.

As a result of the Merger, the Shares are no longer traded on The NASDAQ Global Select Market, there is no public market for the Shares and registration of the Shares under the Securities Exchange Act of 1934, as amended, will be terminated.

As of the date of this Schedule 13D, and except as otherwise provided in the Offer to Purchase, the business and operations of TradeStation have been continued substantially as they were being conducted prior to the Merger.
