⚙️ 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

📖 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.

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.
