Winner: Interactive Brokers


Websites


thinkorswim begins as a browser-based trading platform. To launch it, simply click on the Trade tab in the main menu and select the link for “thinkorswim Web.”


ThinkorSwim vs IBKR


In this mode, thinkorswim has some useful features, including time & sales data and an equity scanner. Charts have technical studies and a handful of drawing tools. There are two trade tickets that deliver lots of powerful order types, including stop and limit on close. To top it all off, there is a simulated mode called paperMoney that really helps to practice the software with zero risk.

Over at Interactive Brokers, there is not a discrete web-based platform. However, charting and trading are possible on the website proper, and there are some fantastic tools here. During our probing, we found one order form with 9 trade types and a price management algo feature to bring an order to a professional level. Stop-loss and take-profit orders can easily be added to an initial order.


Interactive Brokers vs thinkorswim


Charts on the IBKR site have all sorts of bells and whistles with lots of plot styles and plenty of technical studies. The one downside is the lack of any paper trading.

Winner: Pretty close overall


Mobile Apps


thinkorswim makes its second appearance in mobile form. Unfortunately, demo trading is lost, although there are some extra features on the mobile system. For example, we found video news from Schwab Network and CNBC. There are also chat rooms where thinkorswim users can talk about the day’s financial news.


TOS vs IBKR


thinkorswim’s order ticket is borrowed from the website, although this time, there are conditions that can be attached to an order, such as custom-time submission. And charts have more technical indicators this time, with the addition of an extra 300 studies.

On the IBKR mobile app, there are far fewer technical studies (about a hundred). Nevertheless, there are three plot styles, and blowing up the chart full-screen delivers ten more plot styles. In this second version, there are lots of drawing tools. Unfortunately, a previous horizontal mode has been removed.


Interactive Brokers vs TOS


Interactive Brokers replaces CNBC and Schwab Network with Bloomberg TV, although it fails to have any chat rooms. We did find mobile check deposit, though, which is missing in action on the thinkorswim app.

Winner: Draw


Desktop Programs


Now we come to the highest level of trading: desktop systems. thinkorswim makes its final appearance, and Trader Workstation makes its first. TWS is Interactive Brokers’ flagship trading system. It has a demo mode and lots of tools that can be used in either live or demo mode. Highlights include advanced charting, an order ticket with powerful trade types, and sophisticated options tools.


IBKR or thinkorswim


thinkorswim has a lot of the same features, including a practice mode to learn this very advanced piece of software. Charts have tons of gadgets and gizmos, and we really like the backtesting tool on the platform.
