Both platforms’ user interfaces look a bit old and may feel outdated. If you want a modern-looking trading platform like Webull, neither will meet that need. Still, thinkorswim’s interface is very functional and flows well, while Active Trader Pro’s interface is easy to use but feels like everything is kept in separate boxes.

Thinkorswim vs. Active Trader Pro Order Entry


Both platforms let you enter orders in different ways, such as by right-clicking on a chart or using buttons like “sell bid” or “buy ask.” However, each has a different main order entry system. Active Trader Pro uses a simple, classic order form where you fill out each part line by line. Thinkorswim has a more complex, detailed order entry system called Active Trader (which is different from Fidelity’s Active Trader Pro).

For beginners, Active Trader Pro is much easier to learn for order entry. For advanced traders, thinkorswim’s system is very powerful and can give you a big speed advantage once you get used to it.
