II. Strategy Configuration Analysis
2.1 Basic Risk Parameters
# ROI Exit Table - Fixed 10% Take Profit
minimal_roi = {
"0": 0.10,
}
# Stop Loss Setting - Fixed 10% (overridden by custom stop)
stoploss = -0.10
# Enable Custom Trailing Stop
use_custom_stoploss = True
use_sell_signal = True
Design Rationale:
- ROI set at 10%, actual exits primarily rely on trailing stop mechanism
- Fixed stop loss at -10% serves as final defense line; custom trailing stop gradually moves up after profit
- Sell signals enabled, providing active exit capability
2.2 Tiered Trailing Stop Parameters
# Hard Stop Loss (when at loss)
pHSL = -0.178 # -17.8%
# Level 1: Triggered at 1.9% profit
pPF_1 = 0.019 # Trigger threshold
pSL_1 = 0.019 # Stop loss protection
# Level 2: Triggered at 6.5% profit
pPF_2 = 0.065 # Trigger threshold
pSL_2 = 0.062 # Stop loss protection
Trailing Stop Logic:
| Profit Range | Stop Loss Protection | Description |
|---|---|---|
| < 1.9% | -17.8% | Use hard stop loss |
| 1.9% ~ 6.5% | Linear interpolation | 1.9% ~ 6.2% |
| > 6.5% | Dynamic upward movement | Follows profit growth |
III. Buy Conditions Detailed Analysis
3.1 Switchable Parameters
The strategy provides two buy condition switches:
buy_is_dip_enabled = True # Enable pullback buying
buy_is_break_enabled = True # Enable breakout buying
3.2 Seven Buy Conditions Detailed
Condition #1: BB Checked (Bollinger Bands Pullback Breakout Combination)
is_BB_checked = is_dip & is_break
# is_dip sub-conditions
- RMI(17) < 49 # Relative Momentum Index below threshold
- CCI(25) <= -116 # Commodity Channel Index oversold
- SRSI_FK < 32 # Stochastic RSI fast line below threshold
# is_break sub-conditions
- bb_delta > 0.025 # Bollinger Bands lower band 2 and 3 gap > 2.5%
- bb_width > 0.095 # Bollinger Bands width > 9.5%
- close_delta > close * 0.012 # Price movement sufficient
- close < bb_lowerband3 * 0.999 # Price near or below 3 standard deviation lower band
Trigger Scenario: Price breaks below Bollinger Bands lower band while momentum indicators show oversold conditions.
Condition #2: Local Uptrend
is_local_uptrend = (
(ema_26 > ema_12) & # Long-term EMA above short-term EMA
(ema_26 - ema_12 > open * 0.022) & # EMA gap sufficiently large

IV. Sell Logic Detailed Analysis
4.1 Sell Signal Combinations
The strategy uses two groups of sell conditions (OR relationship):
Sell Condition Group 1:
(close > sma_9) & # Price above short-term SMA
(close > ma_sell * 1.02) & # Price above sell MA * offset
(rsi > 50) & # RSI enters bullish zone
(volume > 0) & # Has volume
(rsi_fast > rsi_slow) # Fast RSI above slow RSI
Sell Condition Group 2:
(sma_9 > sma_9.shift(1) * 1.005) & # SMA rising slope
(close < hma_50) & # Price below HMA
(close > ma_sell * 1.051) & # Price above sell MA
(volume > 0) &
(rsi_fast > rsi_slow)
4.2 Sell Parameters
| Parameter | Default Value | Description |
|---|---|---|
| base_nb_candles_sell | 23 | Sell MA period |

# BTC 1-day decline protection
btc_5m - btc_1d > btc_1d * buy_btc_safe_1d # BTC daily decline limit
This protection is currently commented out in code and can be enabled for live trading.
VI. Risk Management Features
6.1 Custom Trailing Stop System
The strategy employs a 3-tier tiered trailing stop:
def custom_stoploss(self, pair, trade, current_time, current_rate, current_profit, **kwargs):
HSL = -0.178 # Hard stop loss
if current_profit > 0.065:
# Profit > 6.5%: stop loss follows profit upward
sl_profit = 0.062 + (current_profit - 0.065)
elif current_profit > 0.019:
# Profit 1.9%~6.5%: linear interpolation
sl_profit = 0.019 + ((current_profit - 0.019) * (0.062 - 0.019) / (0.065 - 0.019))
else:
# Profit < 1.9%: use hard stop loss
sl_profit = HSL
return stoploss_from_open(sl_profit, current_profit)
6.2 Multi-Layer Buy Confirmation
Strategy buy condition design:
- Each buy signal has multi-indicator combination verification
- BB_checked condition requires dip + break to be satisfied simultaneously
- Volume filtering avoids low liquidity traps
