Freqtrade Strategy Development

Build profitable trading strategies with disciplined iteration, tight risk management, and data-driven entry/exit rules. Assumes Freqtrade is running via Docker (docker-compose).

Strategy Anatomy

Every Freqtrade strategy requires three methods:

• populate_indicators(dataframe, metadata) — Add technical indicators (RSI, MACD, Bollinger Bands, etc.) to the dataframe
• populate_entry_trend(dataframe, metadata) — Define buy signal logic; set enter_long = 1 when conditions met
• populate_exit_trend(dataframe, metadata) — Define sell signal logic; set exit_long = 1 when conditions met (optional if using ROI/stop-loss)

Key Config Parameters

stoploss = -0.03  # 3% max loss per trade
trailing_stop = True
trailing_stop_positive = 0.01
trailing_stop_positive_offset = 0.02

minimal_roi = {
    "0": 0.04,      # 4% profit target immediately
    "30": 0.02,     # 2% after 30 candles
    "60": 0.01,     # 1% after 60 candles
}

timeframe = "5m"  # or "15m", "1h", etc.
stake_currency = "USDT"
dry_run = True  # Always backtest/dry-run first

Proven Entry Pattern

stoploss = -0.03
trailing_stop = True
trailing_stop_positive = 0.01
trailing_stop_positive_offset = 0.02
minimal_roi = {"0": 0.04, "30": 0.02, "60": 0.01}

# In populate_indicators: calculate RSI, CCI, Bollinger Bands, EMA, Volume SMA

# In populate_entry_trend: only buy when ALL conditions met
conditions = [
    (dataframe['rsi'] < 30),  # Oversold
    (dataframe['cci'] < -100),  # Momentum confirmation
    (dataframe['close'] < dataframe['bb_lowerband']),  # Price near lower band
    (dataframe['volume'] > dataframe['volume_sma']),  # Volume confirms
    (dataframe['bullish_candle']),  # Pattern confirmation
]
dataframe.loc[reduce(lambda x, y: x & y, conditions), 'enter_long'] = 1

Key Lessons Learned

1. Tight stops save accounts — 3% max loss beats 5%, 7%, or 8% every time
2. Quality over quantity — 25 selective trades outperform 308 mediocre ones
3. Win rate alone is meaningless — 63% win rate unprofitable if avg loss is 5x avg gain
4. Selectivity is survival — RSI(30) + CCI(-100) dual filters dramatically reduce noise
5. Test in bear markets — If strategy survives a crash, it works everywhere
6. Volume confirms conviction — Entries without above-average volume fail more often

Useful Indicators

• RSI (14) — Momentum; < 30 = oversold, > 70 = overbought
• CCI — Commodity Channel Index; momentum confirmation; < -100 = deep oversold
• MACD — Trend following; watch for crossovers
• Bollinger Bands — Volatility; price near lower band = potential reversal
• EMA — Trend filter; price above EMA = uptrend
• MFI — Money Flow Index; volume-weighted momentum

Iteration Workflow

1. Write baseline strategy with core entry/exit logic
2. Backtest on 90–120 days of historical data
3. Analyze exit reasons: are you exiting winners or losers too fast?
4. Tighten ONE parameter at a time (e.g., RSI threshold)
5. Backtest same period, compare vs. baseline
6. If better → keep; if worse → revert
7. Test different market conditions (Bull, bear, sideways)
8. Dry-run on live feeds before deploying to live trading

Version Control

Keep all versions: name files MyStrategy_v1.py, MyStrategy_v2.py, etc. Add comments above each change explaining what improved and why. This preserves your iteration history and makes reverting safe.

這個 Skill 質量較好，內容專業且實用。它把 Freqtrade 策略開發的核心知識講得很清楚，從基礎結構到迭代最佳化都有覆蓋，技術指標說明通俗易懂。迭代工作流程尤其有用，提供了一步步最佳化的思路。不過它偏向理論指導，缺少可以直接拿來用的完整策略程式碼示例，對新手來說可能需要補充更多實戰案例。另外有些進階功能沒有涉及，高階使用者可能會覺得深度不夠。總體適合入門和中級開發者打基礎用。
