Survive first, and the podium will follow.
Timothy J. Maxwell is a systematic trader and Visual FoxPro developer based in Ridgewood, New Jersey, who has been building automated trading systems for more than 30 years. He brings together a strong financial and trading background in stocks, futures, options, FX and crypto with decades of software engineering, and describes himself as a business manager with extensive sales and marketing experience.
He started out as a FoxPro developer, building systems that stored and queried large volumes of data, and carried that mindset into the markets: a price history is just another table to test. Since 1993 he has run FoxPro Guru, working as a senior software development consultant for dozens of small, medium and large firms, including banks, hedge funds and other financial institutions.
In 1994 he founded Maxwell Trading, where he works as a trading system architect across stocks, futures, options, FX and crypto. He began as a discretionary chart trader before moving his rules into code on TradeStation, and today specializes in automated trading systems for FX, futures and stocks. Since 2018 he has run CryptoCritic, providing in-depth research, analysis and insight on crypto trading and investing. He has also written for Currency Investor and e-FOREX, and is followed by more than 29,000 people on LinkedIn.
In the World Cup Quarterly Futures Day Trading Championship he finished 4th in Q2 2024, 3rd in Q3 2025 and 5th in Q4 2025. A detailed review of his own trades after 2024 lifted his result from +8.5% to +51.1%. He advocates for risk-adjusted rankings in trading competitions and for strict safeguards in automated trading, a lesson learned from a costly code bug in his FX work.
Interview
You started as a FoxPro developer. How did programming lead you into trading?
FoxPro taught me to think in data. My job was building systems that stored, indexed and queried large volumes of records, and finding the meaningful answer hidden in a pile of rows. When I started looking at markets, I realized a price history is just another table: date, open, high, low, close, volume. The same skills applied.
So I started looking for patterns. What happens after three down days in a row? How often does an opening gap fill? Does a breakout above yesterday's high follow through or reverse? I'd write a small program to test each question, look at the results, and use them to raise the next question. Most ideas went nowhere. That was the point. It was constant experimentation, hundreds of small tests, and every failed idea taught me something about how markets actually behave versus how people assume they behave. Over time, the handful of ideas that kept surviving the data turned into rules, and the rules turned into trading systems. Programming didn't just lead me into trading. It shaped how I trade: skeptical, measured, and always testing.
Maxwell Trading has been around since 1994. What was the market like when you first started building trading systems?
I actually started the old-fashioned way, trading manually off the charts. I'd study price action, mark levels, and place orders by hand. That was a valuable education, because it taught me how markets feel in real time: how fear and greed show up in the bars, and how hard it is to follow your own rules when money is on the line.
The limitation was obvious, though. I couldn't test an idea across years of data by hand, and I couldn't trust myself to execute perfectly every time. Moving to TradeStation was the turning point. Suddenly I could write my rules in code, back test them across years of history in minutes, and let the platform execute them without hesitation or second-guessing. For someone with a programming background, that was a natural fit.
The market itself was very different then. Data was expensive, commissions were high, and computing power was a fraction of what we have now. But simple, well-built systems still had a real edge, because far fewer people were running code against the market. The same breakout or trend rule that's crowded today worked well back then simply because not many people were doing it.
