John Hart

What’s your role in keeping things running smoothly at TD Ameritrade?

I’m the Managing Director, Trading Products Development. It’s a long title, which is why I settle for something shorter, like Problem Solver. I am responsible for the product design and development of all of our trading platforms, including thinkorswim®, thinkorswim Mobile, TD Ameritrade Mobile Trader, Trade Architect®, and thinkpipes® (our institutional streaming trading platform).

I am always on the lookout for new, innovative ideas that can help our clients have a more streamlined experience with tools that will surprise and delight them. 

What’s your greatest challenge in fulfilling that role?
Staying on top of the latest technology, and the technology that has been widely adopted. Building trading platforms today is a balancing act between knowing what is possible and what our clients want, and then properly intersecting those two. We are constantly navigating in uncharted territories in both technology and in client and service interactions. Being able to see the obstacles quickly, and overcoming them, is deeply satisfying.

What have you done within the field?
I began as a clerk on the Chicago Stock Exchange fresh out of grad school with a computer science and engineering degree and quickly began managing an ETF specialists desk and trading as a specialist myself. I then moved to a proprietary futures trading firm, building and running automated trading strategies, then to TD Ameritrade, where I was responsible for building and introducing forex trading to thinkorswim users. Soon after that I shifted to platform development and began managing the mobile applications. I’ve been trading since 1989.

What’s a “Golden Rule” you live by? (Could be market-related, or anything else)

This is a small world and we get one chance, be respectful and make it count.

When not working you can find me …
When I find myself at home in Chicago, I am an avid cook.

Tell us something the world doesn’t know about you.
Once, stranded in the middle of a large lake, I fixed the broken fan belt in the boat I was in with only dental floss and duct tape, and the fix lasted for weeks.
