⚙️ 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
📚 Classic technical analysis, popularized by John Murphy

📉 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.
