The Patient One

📊 Swing Trader 📅 66 years old (Born 1960)

"The fast moving average is the heartbeat. The slow moving average is the breath. When heartbeat crosses breath, the market has made its decision."

Elegant woman in her mid-60s with silver hair in a neat bun. Minimalist wardrobe—black turtleneck, simple silver watch. Her desk is immaculate, containing only what is essential.

⚙️ Trading Strategy

EMA crossover - 9 EMA crossing 21 EMA signals entry

Monitors the 9-period and 21-period Exponential Moving Averages. When the fast EMA (9) crosses above the slow EMA (21), it signals bullish momentum and triggers a buy. The opposite cross triggers a sell.

🎯 Best Suited For

Stocks with clean trending behavior

"The trend is your friend until it bends."

📜 Why This Strategy Works

Markets trend roughly 30% of the time—but that's where the big money is made. The crossover filters out noise and identifies when momentum has genuinely shifted.

Mathematical Formula

CODE VERIFIED — These formulas are extracted directly from the simulation engine and verified against the source code.
Source: scripts/run-*-simulation.php

📊 Exponential Moving Average (EMA)

EMAt = (Close × k) + (EMAt-1 × (1 - k))
Unlike SMA, EMA weighs recent prices more heavily. The multiplier k controls sensitivity.
k = Smoothing Factor = 2 ÷ (Period + 1)
For 9 EMA: k = 2 ÷ 10 = 0.20 (20% weight to current price)
For 21 EMA: k = 2 ÷ 22 ≈ 0.0909 (9.09% weight to current price)
First EMA = SMA of first n periods (seeding)
📚 Robert Goodell Brown's "Smoothing, Forecasting and Prediction" (1963)

📊 Golden Cross (Buy Signal)

Signal = (EMAfast,t-1 ≤ EMAslow,t-1) AND (EMAfast,t > EMAslow,t)
The moment the fast EMA crosses ABOVE the slow EMA indicates bullish momentum shift.
EMA_fast = 9-period EMA (the "heartbeat")
EMA_slow = 21-period EMA (the "breath")
Cross detected: previous bar fast ≤ slow, current bar fast > slow
📚 Richard Donchian's trend-following system (1960s)

📊 Death Cross (Sell Signal)

Signal = (EMAfast,t-1 ≥ EMAslow,t-1) AND (EMAfast,t < EMAslow,t)
The moment the fast EMA crosses BELOW the slow EMA indicates bearish momentum shift.
Fast EMA falls below slow EMA = trend reversal
Exit signal overrides hold, even if target not reached

📉 Exit Conditions

• TARGET: Price ≥ entry × 1.08 (+8% gain)
• STOP_LOSS: Price ≤ entry × 0.95 (-5% loss)
• DEATH_CROSS: Fast EMA crosses below Slow EMA
• MAX_HOLD: Hold time ≥ 60 days

📖 Historical Origin

Origin: Richard Donchian, Father of Trend Following

Richard Donchian began trading in the 1930s but didn't formalize his moving average crossover systems until the 1960s. His insight was profound: you don't need to predict where markets will go—you only need to recognize when they've started going there.

📖 Understanding Score & Momentum columns
📊 Score — Lifetime Quality Score
Measures how well this strategy+symbol combination has performed across the entire simulation history. Based on return, win rate, drawdown control, profit factor, and trade count. Higher is better.
75+ Elite   60+ Good   40+ Fair   <40 Weak
⚡ Mom — 30-Day Momentum Score
Measures performance over the last 30 days only. Same quality model but calibrated for short-term activity. Captures recent regime shifts that the lifetime score may miss.
75+ Hot   60+ Active   40+ Moderate   <40 Quiet
Spread Indicators — Comparing Mom vs Score reveals regime sensitivity:
🔥 Heating Up — Mom is 20+ points above Score. This symbol is performing significantly better recently than its lifetime average. Could indicate a favorable regime shift.
🧊 Cooling Off — Mom is 20+ points below Score. This symbol is underperforming recently despite a strong lifetime track record. Could indicate an unfavorable regime shift.
No icon = Steady — Scores within ±20 points. Consistent performance.

👤 Personality

Zen-like patience. Never chases trades. Believes rushing leads to ruin. Speaks slowly and deliberately. Has been known to wait months for the perfect entry.
