Ed Seykota is the trader who put trend following on a computer. In 1970, working at a brokerage house, he began testing mechanical trading rules using punched-card computers, and in doing so helped create the discipline now called systematic trading. He is better known to most traders through Jack Schwager’s Market Wizards, where his interview reads less like a technical manual than a description of how a person should relate to their own trading. This profile covers who he is, what he actually built, what the interview teaches, and where the honest limits of copying him sit. He sits alongside the other systematic pioneers in our famous traders collection.
Who Is Ed Seykota?
Edward Arthur Seykota was born in 1946 and earned bachelor’s degrees from MIT in electrical engineering and from the MIT Sloan School of Management, both in 1969. He came to systematic trading through a letter by Richard Donchian describing mechanical trend-following rules, including Donchian’s moving average system. Rather than take the claim on faith, Seykota wrote a program on punched cards to test whether it held up, found that it did, and built his career on the result.
In 1970 he developed a computerised trading system for the futures markets at the brokerage house where he worked, testing on an IBM mainframe, and the firm went on to adopt it. He later left to manage client accounts independently. Two details from the early years are worth keeping. He once quit an analyst job covering egg and broiler markets because he was refused access to the company computer, which tells you how central testing was to him from the start. And his first system was built on exponential moving averages, refined over years into something that suited how he personally wanted to trade rather than into something theoretically optimal.
His trading record is best known through the Market Wizards interview. The account usually cited is a single client account opened with $5,000 in 1972, which by mid-1988 was reported to be up more than 250,000% on a cash-on-cash basis, in the region of $15 million. Three qualifications belong with that number. It comes from an interview rather than from audited public disclosures. The account took withdrawals along the way, which Schwager notes would make the underlying percentage gain considerably larger again. And secondary sources frequently describe this as a twelve-year record rather than a sixteen-year one, which does not square with the 1972 and mid-1988 dates given in the original; sixteen is what those dates produce. Read the figure as an indication of what the method achieved over that span, not as a performance number to be compared against anything.
How Seykota Approached Systematic Trend Following
Seykota’s method was mechanical trend following: identify a trend using objective rules, ride it, exit when the rules say so, and control the size of every position so that no single trade can do real damage. He was explicit that the exits and the money management mattered more than the entries, which remains the most consistently ignored lesson in the field.
The second structural feature of his approach was that he did not chase system perfection. His view was that a system does not need constant modification, and that the useful work is finding or building one compatible with the person running it. That idea, obvious once stated, is why two traders with the same rules get different outcomes, and it sits at the heart of how we approach trend trading and system selection.
Key Lessons From the Market Wizards Interview
Four ideas from that interview have aged particularly well.
Risk management is the whole discipline. Seykota’s often-repeated formulation of the essentials of good trading reduces almost entirely to cutting losses. Everything else is secondary, and traders who invert that order tend not to last.
Your results reflect what you actually want. His best-known line, that everybody gets what they want out of the markets, is uncomfortable precisely because it reframes self-sabotage as preference. A trader who consistently blows up may want excitement more than money, and until that is faced, no system fixes it.
Fit beats optimisation. A system you are compatible with, traded consistently, outperforms a theoretically superior system you keep overriding.
Longevity is the real scoreboard. The line he is most often quoted for on risk, that there are old traders and bold traders but very few old, bold traders, is a compact argument for sizing positions so that survival is never in question. It is worth noting that his systems ran end of day rather than intraday, which is part of why the approach was sustainable over decades.
What Retail Traders Can and Cannot Copy
What transfers is nearly everything conceptual: mechanical rules, testing before trading, risk control as the primary discipline, and matching the method to the person. Those are available to anyone with a laptop and the patience to do the work, and they are more accessible now than at any point in Seykota’s career, since the computing he had to fight for is on your desk.
What does not transfer is the context. He traded futures across markets that were considerably less crowded than they are now, in an era when computerised testing was itself an edge. Being one of a handful of people running mechanical systems is not the same as being one of millions. Anyone reading his record as a template for expected returns is misreading it. Read it instead as a demonstration that the approach works when applied with discipline, then do your own backtesting to find out what is available in the markets you actually trade.
Seykota’s Influence on Modern Systematic Trading
The line from Donchian through Seykota to the trend-following industry that followed is direct. He demonstrated that mechanical rules could be tested on a computer and then traded profitably with real money, which was not an established fact when he started, and he helped move trading from an intuitive craft toward an engineering discipline. The same shift, taken to its limit with vastly greater resources, produced Jim Simons’ record at Renaissance Technologies. Michael Marcus, who worked alongside him at the brokerage early on and credits Seykota as the person who taught him, became a Market Wizard in his own right and was the one who recommended Seykota to Schwager in the first place. Whether that discipline could be taught to complete novices was tested directly a decade later by Richard Dennis and the Turtle Traders.
He also contributed something less technical. In 1992 he began gathering traders to work on the emotional side of trading, developing what became the Trading Tribe Process and writing about it in his 2005 book The Trading Tribe. Long before trading psychology became a standard topic, he was arguing that the trader is part of the system. If you want to go further into the source material, his Market Wizards chapter is the natural starting point, and our trading books library covers the wider canon.
For the structured path from these ideas to a running portfolio of your own tested systems, that is what the Trader Success System is built to deliver.
Frequently Asked Questions
Who is Ed Seykota?
A commodities trader who pioneered computerised trend-following systems from 1970 onward, first at a brokerage house and later managing client accounts independently. He is widely known through his interview in Jack Schwager’s Market Wizards and for founding the Trading Tribe.
What was Ed Seykota’s trading strategy?
Mechanical trend following, originally built on exponential moving averages, with strict predefined exits and volatility-aware position sizing. He treated risk control and compatibility between trader and system as more important than entry signals.
How much money did Ed Seykota make?
The figure usually cited comes from his Market Wizards interview: a client account opened with $5,000 in 1972 was reported to be up more than 250,000% by mid-1988, in the region of $15 million. Those are reported rather than audited figures, the account took withdrawals over the period, and his own net worth has never been public. It is not a benchmark to measure yourself against.
What can traders learn from Ed Seykota today?
Test before you trade, treat cutting losses as the core skill rather than a detail, size positions so that survival is never in question, and choose a method you are genuinely compatible with. The technology has changed completely since 1970; those four principles have not.
