Seb Strategy: The "Minimalist" of EMA Crossovers
Nickname: The EMA Prince Role: Trend Follower Timeframe: 5 minutes
I. What is This Strategy?
Simply put, Seb is:
- Code so simple you'll question your life choices
- Just one buy condition, one sell condition
- Uses EMA crossover + Heikin Ashi candles to confirm trends
Like a craftsman who does one thing but does it well - not fancy, but effective.
II. Core Configuration: "Lock Profits, Don't Be Greedy"
Take Profit Rules (ROI Table)
Immediately → 5% profit? Take it
20 minutes → 4% is fine too
30 minutes → 3% is acceptable
60 minutes → 1% is whatever
Translation: This strategy is the "take what you get" type - profit targets decrease over time, doesn't fall in love with positions.
Stop-Loss Rules
Hard stop-loss: -10% (final line)
Trailing stop: Activates at 2% profit, exits on 1% pullback
Translation: Accept -10% as a loss, but once you're profitable, set protection - don't let gains become losses.
Example:
- Entry price $100
- Rises to $102 (2% profit), trailing stop activates
- Stop set at $101 (1% pullback)
- Continues to $105, stop rises to $103.95
- Pulls back to $103.95, auto-sell, locks in ~4% profit
III. Buy Conditions: Just One, Simple and Direct
The Only Buy Signal
Condition Breakdown:
| Condition | Plain English |
|---|---|
| EMA20 crosses above EMA50 | Short-term MA golden cross above medium-term MA |
| HA close > EMA20 | Price above MA |
| HA green candle | Heikin Ashi is green (bullish) |
Plain English:
"Short-term MA crosses above medium-term MA, price above MA, and it's a bullish candle - BUY!"
Translation:
- EMA Crossover: Like seeing a green light, you can go
- Price Above MA: Like having tailwind, less resistance
- Green Candle: Like clear road ahead, no worries
IV. Sell Logic: Also Just One, Symmetrical Design
The Only Sell Signal
Condition Breakdown:
| Condition | Plain English |
|---|---|
| EMA50 crosses above EMA100 | Medium-term MA golden cross above long-term MA |
| HA close < EMA20 | Price below MA |
| HA red candle | Heikin Ashi is red (bearish) |
Plain English:
"Medium-term MA crosses above long-term MA, price breaks below short-term MA, and it's a bearish candle - SELL!"
Wait, isn't this a "golden cross"? Why sell?
Key Point: The logic uses different periods for buy and sell:
- Buy: EMA20/50
- Sell: EMA50/100
Plain English:
"Buy looks at 'small trend starting', sell looks at 'big trend reversing'."
V. This Strategy's "Personality"
Pros (The Good Stuff)
- Simple and Understandable: Code is clean, even beginners can understand
- Trend Confirmation: Dual verification (MA + candle), not guessing
- Trailing Stop: Auto-protection after profit, not greedy
- Official Example: Produced by freqtrade, standard code
- High Extensibility: Pre-calculated many indicators, easy to optimize
Cons (The Not-So-Good Stuff)
- Few Signals: Only one buy condition, low trading frequency
- Oscillating Markets Kill: May get repeatedly stopped out in sideways
- Wasted Indicators: Calculated a bunch but doesn't use them
- Unoptimized Parameters: Buy/sell params are decoration, you have to tune
VI. Applicable Scenarios: When to Use It?
| Market Environment | Recommendation | Reason |
|---|---|---|
| Clear Trend | ✅ Default parameters | MA crossover strategy's home field |
| Sideways Oscillation | ⚠️ Widen stop-loss | May get frequent false breakouts |
| Rapid Decline | ❌ Don't use | Very few buy signals, no short protection |
| Low Volatility | ⚠️ Extend timeframe | Can try 15m or 1h |
VII. What Market Can This Strategy Make Money In?
7.1 Core Logic: Trend Following, No Dips, No Tops
Seb is a classic trend following strategy. Its profit philosophy:
"Get on when trend comes, get off when trend goes, do nothing in between."
- Trend Identification: EMA crossover tells you trend direction
- Trend Confirmation: Heikin Ashi filters false signals
- Trend Protection: Trailing stop locks in profits
7.2 Performance in Different Markets (Plain English)
| Market Type | Rating | Plain English |
|---|---|---|
| Uptrend | ⭐⭐⭐⭐⭐ | MA crossover perfectly captures trend, money maker |
| Oscillating Market | ⭐⭐☆☆☆ | Repeated slaps in the face, stop-losses galore |
| Downtrend | ⭐☆☆☆☆ | Almost no buy signals, just watching |
| Fast Volatility | ⭐⭐⭐☆☆ | Trailing stop can protect some profits |
One Line Summary: Use when there's trend, hide when sideways.

8.1 Trading Pair Configuration
| Configuration | Recommended | Comment |
|---|---|---|
| timeframe | 5m | Default, can try 3m or 15m |
| trailing_stop_positive | 0.01 | Trail distance 1%, can adjust to 1.5% |
| trailing_stop_positive_offset | 0.02 | Activation threshold 2%, can adjust to 2.5% |
8.2 Hardware Requirements (So Minimal!)
This strategy has simple calculations, very low machine requirements:
| Trading Pairs | Min Memory | Recommended | Experience |
|---|---|---|---|
| 1-50 pairs | 1GB | 2GB | Runs easily |
| 50-100 pairs | 2GB | 4GB | No pressure |
| 100+ pairs | 4GB | 8GB | Piece of cake |
Tip: This strategy is truly resource-friendly, old computers can run it.
8.3 Optimization Suggestions
Code calculates a bunch of indicators but doesn't use:
Used: EMA20, EMA50, EMA100, Heikin Ashi
Unused: RSI, MACD, Bollinger, Stochastic, ADX, CCI, SAR, Fisher RSI, Hammer
You can add filters to entry conditions:
# Example: Add RSI filter
(dataframe['rsi'] < 70) # Don't buy when overbought
Or use Hyperopt to optimize parameters:
buy_rsi = IntParameter(low=1, high=100, default=30, space='buy', optimize=True)
sell_rsi = IntParameter(low=1, high=100, default=70, space='sell', optimize=True)
IX. Easter Egg: The Strategy Author's "Little Details"
Look carefully at the code, you'll find some interesting things:
-
Calculated tons of indicators, but only uses EMA and HA
"Calculated just in case, for future optimization"
-
Buy/sell params are all Hyperopt parameters
"Default values are examples, you Hyperopt for optimal"
-
Candlestick patterns not used either (Hammer)
"Reserved reversal signals, waiting for your creativity"
-
Code comments are detailed
"This is a teaching strategy, not a money-making strategy"
X. Summary: How Good Is This Strategy?
One-Line Verdict
"Simple to the extreme, just a classic EMA crossover strategy, suitable for learning and optimization."
Who Should Use It?
- ✅ Beginner newbies (clean code, easy to understand)
- ✅ People learning quant (official example)
- ✅ People wanting to optimize themselves (reserved many indicators)
- ✅ Resource-limited machines (low computation)
Who Shouldn't Use It?
- ❌ Those wanting to make money directly (too few signals)
- ❌ Those trading in oscillating markets (false breakouts galore)
- ❌ High-frequency traders (5-minute level)
- ❌ Those not wanting to tune parameters (default params are average)
My Recommendation
- Learn First: Understand EMA crossover and Heikin Ashi principles
- Then Backtest: Verify strategy performance with historical data
- Then Optimize: Use Hyperopt to find optimal parameters
- Finally Live: Start with small capital, see actual results
XI. ⚠️ Risk Re-emphasis (Must Read)
Backtesting Looks Great, Live Needs Caution
Seb as an official example strategy was designed for teaching —
It shows how to write a complete strategy, but doesn't guarantee profits.
Simply put: The code is textbook quality, not money-printing machine quality.
Hidden Strategy Risks
In live trading, you may encounter:
- Too Few Signals: Wait forever for a buy
- False Breakouts: EMA crossover then immediately reverses
- Trailing Stop Sweeps: High volatility easily swept out
- Lagging Trend Judgment: MAs always lag behind price
My Suggestion (Honest Truth)
1. Treat it as a learning template, not a money-making machine
2. Use Hyperopt to optimize parameters, don't use defaults
3. Add some filter conditions to improve signal quality
4. Backtest at least a year to verify strategy effectiveness
5. Start with small capital, don't go all-in from the start
Remember: Simple strategies are easy to understand but also easy for the market to "play with". Add more filter conditions, improving win rate is the way!
XII. Final Note
Strategy Positioning
Seb is a teaching strategy:
- Standard code structure
- Complete indicator calculations
- Detailed comments
- Easy to extend
Its value isn't in making money directly, but in teaching you how to write strategies.
