Traders rely heavily on tools. Today’s trading platforms are not only web-based, but also desktop-based, and are becoming increasingly mobile-based as well. Advanced charting, options tools, screeners, hotkeys, virtual trading, watch lists, ladders, Level 2 quotes, and backtesting are just a sampling of the functionality brokers make available to their customers. Over the years, I have learned it is not just the trading tools that separate brokers, but the design, depth, speed, and overall execution of delivering the ultimate trading experience. This is where brokers such as TD Ameritrade’s thinkorswim and our honorable mention tastytrade really excel. After spending many hours on both desktop platforms, I give thinkorswim the edge, thanks to its modern feel and outstanding trader tools; however, both platforms execute so well that it truly comes down to personal preference. Diehard fans exist for both, and either one is a great choice for seasoned traders.
