Evolving Alpha combines the battle-tested Turtle Trading system with an AI self-improvement engine — a trend following strategy that gets smarter with every signal it takes.
"I think you need the conceptual apparatus to be the first thing you start with and the last thing you look at." — Richard Dennis
In 1983, legendary Chicago trader Richard Dennis made a $1 million wager with his partner William Eckhardt. Dennis believed trading could be taught to anyone. Eckhardt believed it required innate talent.
Dennis recruited 23 ordinary people — a security guard, a card player, an actor — and taught them a simple, mechanical trend-following system. He called them the Turtle Traders.
Over four years, his Turtles generated over $175 million in profits. The system worked not because of instinct, but because of rules followed without exception. Evolving Alpha is built on those same rules — then taken further with AI-driven self-improvement.
Dennis recruits 23 traders, teaches a complete mechanical system in two weeks. No prior experience required.
Turtles begin trading futures using strict breakout rules and ATR-based position sizing.
The experiment concludes. Dennis proves systems beat instinct, every time.
The original rules rebuilt for modern ETF markets, with an AI self-improvement engine layered on top.
Most algorithmic strategies are static — fixed rules that never change. Evolving Alpha is different. After every trade, an AI engine analyses what happened, identifies patterns, and proposes parameter improvements — with simulation evidence required before any change is applied.
After every closed trade, our AI engine writes a detailed post-mortem — root cause of the win or loss, market conditions at entry, pattern tags, and one actionable lesson.
After every 5 trades, the AI reviews all post-mortems collectively and identifies recurring patterns across wins and losses.
When a pattern is statistically significant (minimum 10 trades), the AI proposes a single, conservative parameter change with full pro/con analysis.
Every proposed change is backtested against the full historical dataset before consideration. If the simulation does not show meaningful improvement over the baseline, the proposal is automatically rejected.
Proposals that pass simulation are submitted for human review with full evidence. No change is ever applied silently or automatically.
The strategy evolves based on the results of rigorous analysis. Market parameters are refined continuously based on the market environment and context — ensuring the system adapts to changing conditions rather than remaining static.
The mechanical system checks SPY once per day after market close. When all conditions align, a position is entered automatically. The AI layer observes, learns, and proposes refinements over time.
The primary entry fires when SPY's closing price surpasses a proprietary breakout level — signalling a potential sustained trend. This is our primary signal, always taken when all conditions are met.
A confirmation signal that activates under specific market conditions. When the primary signal has recently succeeded, this signal is suspended — preserving signal quality and preventing overtrading.
Even when a breakout occurs, no trade is taken unless our proprietary trend strength indicator confirms a directional market. When the market is directionless or choppy, all signals are ignored — protecting capital during unfavourable conditions.
Every position is sized to risk a fixed percentage of account equity, using current market volatility as the guide. When markets are volatile, sizes shrink automatically. When calm, sizes grow. Risk per signal is constant regardless of market conditions.
When a trade moves in our favour by a defined volatility increment, additional units are added as the trade proves itself. Each addition tightens all previous stops. This creates asymmetric positions: small losses on failed breakouts, large gains when trends run.
Positions close on whichever triggers first: a volatility-adjusted hard stop from entry, or a trailing exit when price closes below a proprietary lookback level. Winners run until the trend exhausts. Losers are cut short automatically.
After every closed trade, our proprietary engine analyses conditions at entry, trade behaviour, and outcome. Patterns are identified and lessons extracted. As the trade record grows, recurring patterns trigger parameter refinement proposals — with simulation evidence required before any change is considered.
All strategy parameters can evolve based on evidence from live trading and backtesting. Every proposed change must beat the baseline in simulation before consideration. The strategy becomes more refined over time as market conditions evolve.
With fewer than ten trades per year, capital sits idle most of the time. When no position is open, the system automatically parks cash in money market instruments to earn yield. When a new signal fires, the money market position is liquidated and capital is deployed into the SPY trade — ensuring every dollar works at all times.
The original Turtle system was designed for 1983 commodity futures. Modern equity markets required targeted updates without abandoning the core principles.
Original Turtles traded 20+ commodity futures. We focus on SPY — the S&P 500 ETF — for deep liquidity, zero commission, and correlation with the US equity trend.
Evolving Alpha trades both long AND short. When SPY breaks above our proprietary signal level, we go long. When it breaks below, we go short. The strategy profits in bull and bear markets alike.
The original Turtle system had no trend quality filter. Evolving Alpha adds a proprietary trend strength filter as a mandatory pre-condition — significantly reducing false breakouts while preserving high-quality trend entries.
Original Turtles entered intraday on the breakout day. We enter the next day's market open after a confirmed daily close — eliminating intraday whipsaws that reverse before close.
With fewer than ten trades per year, idle cash earns nothing in the original system. Evolving Alpha automatically sweeps idle capital into money market instruments between trades — capturing yield while waiting for the next signal.
When a new breakout signal fires, the money market position is liquidated instantly before entering SPY. Every dollar is always deployed — either riding a trend or earning yield. No idle cash, no wasted opportunity.
No jargon. No black box. Here is exactly what the system does every day, why it does it, and how it makes money.
The system waits for the market to show its hand, then follows. When SPY starts moving strongly in one direction, the system gets on board and rides it. When it stops trending, the system gets out. No forecasting. No opinions. No news. Just price and a set of mathematical rules — followed without exception.
Every day the system checks whether SPY has closed above or below its proprietary breakout channel. If today breaks above the upper channel, SPY is at a level it has not recently seen — a signal that a new uptrend may be starting. The system goes long. The reverse applies for shorts.
Think of it this way: if a stock has not been this high in several weeks and it just broke through, something meaningful may be happening.
ADX measures how strongly the market is trending on a scale of 0 to 100. It does not tell you which direction — just whether there IS a direction. Low ADX means a choppy, directionless market. High ADX means a real trend is forming or already underway.
Evolving Alpha only takes signals when ADX exceeds a proprietary threshold. This filters out false alarms — breakouts that happen when the market is drifting sideways with no real conviction behind them.
This filter significantly reduces the number of false breakout signals acted upon.
ATR measures how much SPY moves on an average day. Evolving Alpha uses ATR for two things: position sizing and stop placement. Every trade risks a fixed percentage of account equity — but the number of shares adjusts based on current volatility. In turbulent markets, fewer shares. In calm markets, more.
The hard stop is placed at a proprietary volatility-adjusted level below entry — far enough to survive normal daily noise, close enough to limit losses if the breakout fails.
SPY closes above its breakout level and trend is confirmed. Position sized automatically using current volatility. Buy order placed at next morning's market open.
If the trade moves in our favour, additional units are added as the position proves itself. Each addition tightens all stops. Winning trades grow as they demonstrate strength.
If price falls to a volatility-adjusted level below entry, the position closes immediately. No exceptions. This is the maximum loss on any trade — always defined before entry.
If SPY closes below its proprietary trailing exit level, the trend is considered over and the position closes. This lets winners run for weeks while ensuring losses are cut quickly.
Most trades will be small losses — the market breaks out, does not follow through, the stop is hit, and we lose 1R (one unit of risk). But when a real trend develops, the trailing exit lets it run — sometimes 3R, 5R, even 10R on a single trade.
Over time, winning trades that average several multiples of risk produce strong profit factors — highly profitable even without a majority win rate. Our proprietary trend filter pushes that ratio further by reducing false breakouts without touching the quality of genuine trends.
The AI layer makes it better over time. Every closed trade is analysed. Every pattern is identified. Every proposed improvement is tested in simulation before it reaches subscribers. The system does not just follow the market — it learns from it.
No finance degree required. Here is what every term in the Evolving Alpha strategy actually means in plain English.
ATR measures the average distance between the highest and lowest price of SPY over a rolling lookback period, including overnight gaps. It gives a reliable measure of how much the market moves on a typical day.
Evolving Alpha uses ATR for two things. First, to set the stop loss — always placed a proprietary multiple of ATR from entry, far enough to survive normal daily noise. Second, to size positions — buying fewer shares when volatility is high so every trade risks the same dollar amount.
Think of it as a weather forecast for the market. High ATR means stormy conditions — trade smaller. Low ATR means calm — trade larger.
ADX measures trend strength on a scale of 0 to 100. It does not tell you which direction the market is moving — only whether it IS moving in a sustained direction. Low ADX means a choppy, directionless market. High ADX means a real trend is forming or already underway.
Evolving Alpha requires ADX above a proprietary threshold before taking any signal. This filters out false breakouts that happen when the market is just drifting sideways with no real conviction.
Think of ADX as the confidence meter. A breakout during a strong trend is credible. A breakout during a directionless market is likely just noise.
A Donchian Channel tracks the highest closing price and the lowest closing price over a set lookback period. Evolving Alpha uses a proprietary Donchian Channel calibrated to capture meaningful trend signals without excessive noise.
When SPY closes above the channel high, it means the market has broken into new territory — a potential new uptrend. When it closes below the channel low, a potential downtrend. These are the entry signals.
Named after Richard Donchian, the father of trend following, who pioneered systematic breakout trading in the 1970s.
R-Multiple measures how much you made relative to how much you risked. A positive R-Multiple means the trade was profitable. The higher the number, the more the trade returned relative to its risk.
Evolving Alpha is designed to produce large positive R-Multiples on winning trades while keeping losses small and defined.
Profit factor is the total dollar amount won divided by the total dollar amount lost across all trades. A profit factor of 1.0 means break-even. Above 1.0 means profitable. Evolving Alpha's current backtest profit factor of 5.83 means for every $1 lost, the system made $5.83.
Most professional traders consider a profit factor above 1.5 to be good. Above 2.0 is excellent. Above 3.0 is exceptional. A high profit factor combined with a selective signal count means each trade carries significant weight.
Pyramiding means adding to a position that is already moving in your favour. As a trade proves itself, additional units are added — each one sized to the same fixed-risk rule. Every addition tightens all previous stops.
This creates the asymmetry that defines trend following — small losses on failed signals, outsized gains when a genuine trend develops.
Drawdown measures the decline from the highest point your account has reached to its current value, expressed as a percentage. It is one of the most important metrics for evaluating a trading strategy — alongside returns.
Evolving Alpha's two-year backtest results show an exceptionally low maximum drawdown of 3.0%. In live trading, drawdowns may vary significantly from backtest results — they are a true testament to a strategy's risk management protocols. Subscribers should expect drawdowns that deviate from the exceptional figure achieved in backtesting. The system monitors drawdown continuously and halts automatically if a predefined threshold is breached.
Low drawdown is as important as high returns. A system that compounds steadily with controlled drawdowns is far easier to follow — and far more effective — than one with volatile swings, regardless of headline returns.
