Turtle Traders

The trading experiment that Chicago futures trader Richard Dennis and his partner William Eckhardt ran from December 1983: two classes of novices — 21 men and two women in most accounts — recruited through newspaper advertisements, taught a mechanical breakout trend-following system in about two weeks and given accounts of Dennis's own money, to settle an argument over whether trading could be taught. Its story turns on rules versus discipline: the rules (20- and 55-day Donchian breakouts, positions sized by the market's average true range "N", 2-N stops, pyramiding to four units) were simple and are now free, but the results varied widely between trainees given the same rules, and Dennis himself — the teacher — lost about half of his two public funds in 1987–88 and stopped managing outside money (Turtle / Donchian Breakout). The performance record is the weakest in this batch of profiles: the often-quoted "$175m" of Turtle profits rests on a former Turtle's statement, Michael Covel's own site says "$100M+", and the best contemporary number is a *1989 Wall Street Journal* tabulation that 14 Turtles trading as CTAs averaged about 80% a year** compounded over roughly four and a half years (as cited by secondary sources — verify). None of these is an audited composite. What is solid is that several Turtles went on to run registered CTAs with public records for decades — Chesapeake Capital above all.

At a glance

Founded
Recruited from late 1983 (first class trained Dec 1983, trading from Jan 1984) and late 1984 (second class, trained Dec 1984) (Wikipedia, citing Covel and press — secondary)
Headquarters
Chicago — Dennis's firm C&D Commodities, at the Chicago Board of Trade (Wikipedia; from memory for the building, verify)
Ownership / structure
Not a firm: a training programme inside Dennis's trading business; trainees traded accounts of Dennis's capital under his rules and shared in profits (terms not public — verify)
Leadership
Richard J. Dennis (born Jan 1949, Chicago; "Prince of the Pit") and William Eckhardt (Dennis's partner; studied mathematics "up to the doctoral level"; later Eckhardt Trading Company) (Wikipedia; The Hedge Fund Journal, Oct 2018)
Programme size
~23 trainees in two classes (21 men, 2 women — Wikipedia); "more than 1,000" applicants (section 15, TurtleTrader.com — secondary, verify); allocations after a trial month of $250,000 to $2m each (Wikipedia, reported)
Systems
Turtle / Donchian Breakout (System 1: 20-day; System 2: 55-day); N-based sizing as an early form of volatility-targeted trend; the evidence for the underlying edge is in Time-Series Momentum
Regulators
CFTC and NFA (Dennis's public funds and the Turtles' later CTAs); the exchanges' rules
Signature moves (incl. failures)
