Dr. Ken Long

Dr. Ken Long is a professional trader, educator, and retired U.S. Army Lieutenant Colonel who founded Tortoise Capital Management. His trading philosophy is rooted in descriptive statistics, systems thinking, and military-style discipline to manage risk in short- to intermediate-term markets.
Core Trading Frameworks
Ken Long is best known for his RLCO (Regression Line Cross Over) framework, which uses a "statistical lens" to identify high-probability setups.

Key Indicators:
RL10, RL30, RL90, RL270: Linear regression lines of various periods used to track price movement against the mean.
The "River" and "Dragon": Visual bands (Bollinger-style) that help traders identify "flood plains" (extreme price moves) and "sideways quiet channels" (SQC).
MACD Seasons: A categorization of market conditions (Spring, Summer, Fall, Winter) based on MACD behavior to determine the appropriate strategy.
Mechanical Patterns: He teaches specific setups like Channeling, Overreaction, Triple Screen, 551W, Five-Day Down, and Wash Out.

Risk Management & Psychology
Long emphasizes "Standard Work" and a professional mindset to overcome fear and greed.

The "Zero-State" Concept: A technique for achieving a neutral, unbiased perspective before entering a trade to minimize impulsive decisions.
R-Multiple Thinking: Focuses on managing the initial risk (1R) and aiming for multiples of that risk in profit.
Core and Turbo Positions: A strategy of blending longer-term "core" holdings with shorter-term "turbo" tactical trades to maximize efficiency.
