The combined entity will provide a suitable platform for independent investors, challenging the mega firm mentality, said the firm.

Upon completion of the merger, the new entity will have a combined client base of nearly 500,000 accounts with several billion dollars in client assets.

TradeKing CEO Don Montanaro said that TradeKing and Zecco share a similar mission, applying pressure on the industry to give the individual investor a far better trading experience and a far greater value.

"By merging, we have an opportunity to ratchet up our ability to influence the direction of the online brokerage industry. We believe this is great news for clients of both firms and investors as a whole," Montanaro said.

The new business will offer both existing and new clients to enjoy a high-performing trading platform with the best tools and social community features, while also availing Zecco capabilities such as forex trading and highly-rated mobile trading apps for both iPhone and Android, claims Zecco.
