Company Background

The story of IB began in the 1970s with founder, chairman, and CEO Thomas Peterffy.

Peterffy, a Hungarian-born programmer-businessman, emigrated to the United States and quickly recognize that computers would transform trading. 

Known for his insistence on automation and algorithmic trading, Peterffy’s relentless pursuit of efficiency in stock trading led to the genesis of T.P. & Co, a market maker created in 1977 — later renamed to Timber Hill Inc.

Thomas Peterffy

In 1993, the IB that we know today was created alongside Interactive Brokers Group Inc. Timber Hill and IB are held under Interactive Brokers Group as subsidiaries. 

IB boasts 24 offices in 12 countries as of this writing. The company is publicly traded, with 16.6% publicly held and the remainders held by Peterffy and the employees at IB.

The brokerage is regulated by the NYSE, SEC, FINRA, FCA, and by other applicable agencies worldwide. 

Drive by Peterffy’s focus on technological automation, IB was able to establish itself as a low-cost brokerage for experienced traders. The company touts a committed following of traders worldwide.

  • Traders’ Calendar App
  • Options Strategies App
  • Probability Lab

Without further ado, we will turn to the section that all of our investors have been waiting for: The IB trading platform. 

Interactive Brokers Commissions and Fees

An astute trader will immediately home in on one of the more important elements of trading: price. IB is known for ruling the brokerage world with bottom-dollar pricing.

Platform and Technology

If you’ve heard anything about IB, you’ve likely been cautioned to stay away unless you are a pro. Novice and intermediate investors that come into contact with IB often report a complicated platform, something akin to the cockpit of a Boeing 737 — and not the newer versions.  

The IB Desktop Trader Workstation, or TWS for short, is the flagship platform. This is where IB puts much of its time and energy.

While complicated, it is full of technology for the sophisticated trader. TWS is not beginner-friendly, but should it be?

Interactive Brokers Trading

Within TWS is a completely customizable workspace that IB calls Mosiac. Add, organize, and subtract everything from charts to scanners, watchlists to alerts.

Interactive Brokers Trades

For the novice traders looking for a challenge, lured in by the ultra-low fees and a slew of investment products, IB has you covered.

WebTrader is an HTML-based simplified and streamlined version of TWS. WebTrader was built for ease-of-use and works behind firewalls.  

Traders on the go can trade through IB’s mobile app, available for both iOS and Android. Users can download the IBKR mobile app to trade whenever inspiration strikes.

Interactive Brokers Mobile App

Also available is the IB Client Portal. The portal consolidates all key information into one easy-to-view dashboard.

Check account balances, quotes, make trades, and explore key performance indicators. 

Last, but not least, for those who find that trading with their hands isn’t fast enough, IB offers iBot.

IBot is an integrated natural language processing tool built into all IB’s trading platforms. Control your trading with voice commands.
