TD Ameritrade is a US-based broker but, unlike most of its US counterparts, it accepts international clients. Founded in 1971 as Ameritrade, in 2006 the company acquired TD Waterhouse from the Canadian financial conglomerate, Toronto-Dominion Bank, which granted it a 40% minority stake. In 2020, the Charles Schwab Corporation acquired TD Ameritrade, which gave Toronto-Dominion Bank 13% ownership of Charles Schwab. The acquisition created an online brokerage powerhouse in the US. TD Ameritrade has over 12,000,000 client accounts worth over $1.2 trillion, and more than 2,100,000 trades are performed each day. Traders have access to the proprietary thinkorswim trading platform, with tens of thousands of assets across multiple sectors and a focus on equity, ETF, and mutual funds.
