II. Strategy Configuration Analysis​

2.1 Basic Risk Parameters​

# ROI Exit Table (time: minimum profit rate)
minimal_roi = {
    "0": 0.10,    # Immediate exit: 10% profit
    "30": 0.05,   # After 30 minutes: 5% profit
    "60": 0.02,   # After 60 minutes: 2% profit
}

# Stop-Loss Settings
stoploss = -0.10  # -10% hard stop-loss

# Trailing Stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.01    # 1% trailing activation point
trailing_stop_positive_offset = 0.03  # 3% offset trigger

Design Philosophy:

  • Uses a time-decaying ROI strategy: the longer the holding period, the lower the exit threshold
  • Pairs with trailing stop to lock in profits, suitable for trending markets
  • Hard stop-loss at -10% controls maximum loss per trade
  • Custom dynamic stop-loss adjusts protection levels based on profit levels

2.2 Order Type Configuration​

order_types = {
    'buy': 'limit',
    'sell': 'limit',
    'trailing_stop_loss': 'limit',
    'stoploss': 'limit',
    'stoploss_on_exchange': False,
    'stoploss_on_exchange_interval': 60,
    'stoploss_on_exchange_limit_ratio': 0.99
}

III. Entry Conditions Details​

3.1 Protection Mechanisms (39 Sets)​

The strategy equips each entry condition with an independent protection parameter set:

  • EMA crossover protection
  • SMA crossover protection
  • Safe dip/rise filtering
  • Volume confirmation

3.2 Entry Condition Classification​

The strategy contains 39 entry conditions, which can be categorized as follows:

Condition GroupCountCore Logic
Bollinger Band Rebound8Price rebounds after touching the lower Bollinger Band
RSI Oversold6Buy when RSI is below a specific threshold
Moving Average Golden Cross10Short-term MA crosses above long-term MA
Volume Confirmation5Volume surge confirms signal validity
Multi-Indicator Combination10Multiple indicators confirm together

3.3 Custom Stop-Loss Logic​

def custom_stoploss(self, pair, trade, current_time, current_rate, current_profit, **kwargs):
    if current_profit > 0.2:
        return 0.05   # Above 20% profit: breakeven stop-loss
    elif current_profit > 0.1:
        return 0.03   # Above 10% profit: 3% stop-loss
    elif current_profit > 0.06:
        return 0.02   # Above 6% profit: 2% stop-loss
    elif current_profit > 0.03:
        return 0.01   # Above 3% profit: 1% stop-loss
    return 1  # Use default stop-loss

IV. Exit Logic Details​

4.1 Multi-Layer Take-Profit System​

Profit Range      Threshold    Action
──────────────────────────────────────────────
[0%, 3%]          0.03        Activate trailing stop
[3%, 6%]          0.06        Tighten stop-loss to 2%
[6%, 10%]         0.10        Tighten stop-loss to 3%
[10%, 20%]        0.20        Tighten stop-loss to 5%
[>20%]            >0.20       Extreme profit protection

4.2 Base Sell Signal​

The strategy contains 1 main sell condition:

  • RSI overbought + price touching the upper Bollinger Band

4.3 HOLD Trade Support​

The strategy supports configuring take-profit strategies for specific trades via the nfi-hold-trades.json file:

  • Set independent take-profit per trade ID
  • Set independent take-profit per trading pair
