IBKR GlobalTrader is a free mobile application available for iPhone users. Developed by Interactive Brokers LLC, it falls under the category of Business & Productivity with a subcategory of Finance. This powerful tool allows users to trade on over 90 stock markets worldwide, including NYSE, NASDAQ, LSE, HKSE, and even cryptocurrencies like Bitcoin, Bitcoin Cash, Ether, and Litecoin.

One of the standout features of IBKR GlobalTrader is the ability to trade fractional shares. This means that no trade is too small, and even expensive stocks can be invested in with as little as $1. This opens up investment opportunities for users with limited capital, allowing them to put their cash balances to work and maximize their returns.

The app also offers a convenient stock swapping feature, enabling users to easily exchange stocks they own for stocks they desire with just a single tap. This flexibility gives investors more control over their portfolio and the ability to adapt to changing market conditions.

For those who are new to trading or want to test their strategies, IBKR GlobalTrader offers a free trial. Users can gain access to $10,000 in simulated cash and trade in a simulated trading environment. Once ready for live trading, users can complete their application, fund their account, and start trading around the world.

It's important to note that margin borrowing, available in the app, is intended for experienced investors with a high risk tolerance. Additionally, users should be aware of the risks involved in online trading, as the potential for substantial losses exists.

Overall, IBKR GlobalTrader is a comprehensive mobile trading app that allows users to access a wide range of stock markets and trade with ease. With its fractional shares feature and stock swapping capability, it offers flexibility and convenience to investors of all levels of experience.
