II. Strategy Configuration Analysis​

2.1 Timeframe Configuration​

timeframe = '5m'      # Main timeframe: 5-minute candles
inf_1h = '1h'         # Information timeframe: 1-hour candles

Strategy uses dual-timeframe analysis:

  • 5-minute candles: Used for generating entry signals and daily monitoring
  • 1-hour candles: Used for calculating long-term trend indicators (such as EMA200_1h, RSI_1h, etc.)

2.2 Take-Profit Configuration​

minimal_roi = {
    "0": 0.10,    # Execute 10% take-profit immediately after 0 minutes
    "30": 0.05,   # Reduce to 5% take-profit after 30 minutes
    "60": 0.02    # Reduce to 2% take-profit after 60 minutes
}

2.3 Stoploss Configuration​

stoploss = -0.99  # Basic stoploss disabled, taken over by custom_stoploss

2.4 Trailing Take-Profit Configuration​

trailing_stop = True
trailing_only_offset_is_reached = False
trailing_stop_positive = 0.01        # 1% trailing amplitude
trailing_stop_positive_offset = 0.025 # 2.5% profit trigger

III. Entry Conditions Details​

The strategy contains 14 independent entry conditions (numbered 0-13), each using different technical indicator combinations. Core logic is: finding opportunities where price pulls back to Bollinger Band lower rail during uptrends.

Condition 0: Basic RSI Oversold​

  • Closing price > EMA200
  • RSI < 30
  • 1-hour RSI < 71

Condition 1: Bollinger Band Dip Buy (Conservative)​

  • Closing price > EMA200 and > EMA200_1h
  • Closing price < BB lower rail × 0.989

Condition 2: Bollinger Band Dip Buy (Aggressive)​

  • Closing price > EMA200
  • Closing price < BB lower rail × 0.982

Conditions 3-4: RSI Dual-Cycle Filter​

  • Closing price > EMA200_1h
  • RSI < 14.2
  • 1-hour RSI < 35

Conditions 5-7: MACD Golden Cross + Bollinger Band​

  • EMA26 > EMA12
  • Closing price < BB lower rail
  • MACD upward

Conditions 8-9: Pure RSI Oversold​

  • 1-hour RSI < 20-35
  • 5-minute RSI < 10-28

Condition 10: 1-Hour Bollinger Band Breakout​

  • 1-hour RSI < 35
  • 1-hour closing price < BB lower rail
  • MACD turns positive

Condition 11: MACD Continuous Uptrend​

  • Consecutive 5 candles MACD Histogram > 0
  • Breaks above middle rail

Condition 12: Volume Contraction + Price Reversal​

  • Volume drops over 60% compared to 48-cycle mean
  • Price rebounds from lower rail

IV. Exit Logic Details​

4.1 Custom Stoploss Function (Core)​

Strategy uses custom_stoploss() to implement tiered stoploss:

Profit RangeStoploss Strategy
Profit < 1.6%Use hard stoploss -8%
Profit 1.6%-8%Linear interpolation calculates stoploss position
Profit > 8%Trailing stoploss starts, locks at least 4% profit

4.2 Exit Signals​

use_exit_signal = True
exit_profit_only = True          # Only exit when profitable
exit_profit_offset = 0.001       # 0.1% profit satisfies

Actual exit condition: Closing price > Bollinger Band middle rail × 1.01

VI. Strategy Pros & Cons​

6.1 Advantages​

  1. Excellent Drawdown Control: Through 8% hard stoploss and dynamic trailing, effectively controls maximum loss
  2. Multiple Entry Conditions: 14 conditions provide rich entry opportunities
  3. Profit Protection: Dynamic trailing ensures profits don't turn into losses
  4. Trend Filtering: EMA200 filter avoids counter-trend trading

6.2 Limitations​

  1. Conservative Design: May exit too early in strong trends
  2. Complex Stoploss Logic: Tiered stoploss increases understanding difficulty
  3. Parameter Sensitivity: Default parameters may not suit all market conditions

VII. Applicable Scenarios​

  • Oscillating Markets: Strategy excels in range-bound markets
  • Moderate Volatility: Suitable for normal volatility environments
  • Trend Pullbacks: Good at capturing pullback opportunities in uptrends
  • Strong Bull Markets: May exit too early, missing major gains
  • Extreme Volatility: Hard stoploss may be triggered frequently
  • Sideways with Low Volume: Entry conditions may be difficult to trigger

VIII. Parameter Optimization​

8.1 Default Parameter Philosophy​

Default parameters are conservatively designed, prioritizing capital protection over aggressive profit seeking. Unless you have specific market understanding, recommended to use default parameters.

8.2 Optimization Directions​

Stoploss Adjustment: Can adjust 8% hard stoploss based on personal risk tolerance. More aggressive traders may increase to 10-12%, conservative traders may reduce to 5-6%.

Take-Profit Adjustment: ROI ladder can be adjusted based on trading style. Short-term traders may lower thresholds, medium-term traders may raise them.

IX. Live Trading Notes​

Conduct sufficient backtesting before live deployment. Test across different market conditions (bull, bear, oscillating). Only deploy strategies performing well in backtests.

9.2 Monitoring During Live Trading​

Monitor strategy performance regularly. Watch for:

  • Stoploss trigger frequency
  • Average profit per trade
  • Maximum drawdown

9.3 Parameter Adjustment​

Adjust parameters cautiously based on market conditions. Avoid frequent changes. Each adjustment should be based on data analysis, not emotions.
