⚙️ 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

📊 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.

👤 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.
