SMAIP3v2 Strategy In-Depth Analysis

Strategy Number: #355 (355th of 465 strategies) Strategy Type: Moving Average Offset + Trend Filter + Dynamic Stop Loss Timeframe: 5 minutes (5m)

I. Strategy Overview​

SMAIP3v2 is a trend-following strategy based on moving average offsets, capturing rebound opportunities after price pullbacks through dynamically calculated buy and sell thresholds. This strategy combines EMA trend filtering and a "bad pair" detection mechanism to avoid extreme market conditions while maintaining trend following.

Core Features​

II. Strategy Configuration Analysis​

2.1 Basic Risk Parameters​

# ROI exit table
minimal_roi = {
    "0": 0.026  # Exit immediately if 2.6% profit achieved
}

# Stop loss setting
stoploss = -0.23  # 23% fixed stop loss

# Trailing stop
trailing_stop = True
trailing_only_offset_is_reached = True
trailing_stop_positive = 0.003  # Start trailing after 0.3% profit
trailing_stop_positive_offset = 0.018  # Activate trailing after 1.8% profit

Design Rationale:

  • ROI setting is relatively aggressive (2.6%), pursuing quick profits
  • Stop loss space is large (23%), leaving room for trend fluctuations
  • Trailing stop mechanism protects accumulated profits, avoiding profit giveback

2.2 Order Type Configuration​

The strategy uses default order type configuration, suitable for most exchanges.

III. Buy Condition Details​

3.1 Protection Mechanism (2 Sets)​

The strategy prevents buying in extreme market conditions through the pair_is_bad detection mechanism:

Protection TypeParameter DescriptionDefault Value
pair_is_bad_1Price drop threshold from open 12 candles ago to current close0.130 (13%)
pair_is_bad_2Price drop threshold from open 6 candles ago to current close0.075 (7.5%)

Logic: When price experiences a sharp decline within the past 6-12 candles (exceeding the threshold), it is marked as a "bad pair" and buying is suspended.

3.2 Core Buy Condition​

# Buy logic
(
    (dataframe['ema_50'] > dataframe['ema_200']) &           # EMA50 above EMA200, trend up
    (dataframe['close'] > dataframe['ema_200']) &             # Close above EMA200
    (dataframe['pair_is_bad'] < 1) &                          # Not in bad pair status
    (dataframe['close'] < dataframe['ma_offset_buy']) &       # Price below buy threshold
    (dataframe['volume'] > 0)                                  # Has volume
)

Condition Analysis:

  1. Trend Confirmation: EMA50 > EMA200, ensuring medium-term trend is upward
  2. Price Position: Close > EMA200, ensuring position in long-term uptrend
  3. Safety Check: Not in "bad pair" status, avoiding chasing highs or catching falling knives
  4. Buy Opportunity: Price below dynamically calculated buy threshold (MA × low_offset)
  5. Liquidity: Ensuring there is trading volume

3.3 Moving Average Offset Mechanism​

The strategy uses dynamic offsets to calculate buy and sell thresholds:

# Buy threshold calculation
ma_offset_buy = SMA/EMA(N candles) × low_offset
# low_offset default 0.968, i.e., 3.2% below the moving average

# Sell threshold calculation
ma_offset_sell = EMA(N candles) × high_offset  
# high_offset default 0.985, i.e., -1.5% above the average (slightly below the average)

IV. Sell Logic Details​

4.1 Sell Condition​

# Sell logic
(
    (dataframe['close'] > dataframe['ma_offset_sell']) &      # Price above sell threshold
    (dataframe['volume'] > 0)                                  # Has volume
)

Design Rationale: Exit with profit when price rebounds above the sell threshold.

4.2 Smart Exit Rejection Mechanism​

The strategy implements a confirm_trade_exit method that rejects selling under certain conditions:

# Exit rejection condition
if sell_reason in ['roi', 'sell_signal', 'trailing_stop_loss']:
    if (last_candle['open'] > previous_candle_1['open']) &    # Current candle opens higher
       (last_candle['rsi'] > 50) &                             # RSI > 50
       (last_candle['rsi'] > previous_candle_1['rsi']):       # RSI rising
        return False  # Reject exit

Design Rationale: When market momentum remains strong (higher open, rising RSI), reject the sell to capture more profit.

4.3 Multi-Layer Take-Profit System​

5.2 Optimizable Parameters​

The strategy provides rich optimizable parameters:

# Buy parameters
base_nb_candles_buy = IntParameter(16, 60, default=18)  # Moving average period
low_offset = DecimalParameter(0.8, 0.99, default=0.968)  # Buy offset
buy_trigger = CategoricalParameter(['SMA', 'EMA'], default='SMA')  # MA type

# Sell parameters
base_nb_candles_sell = IntParameter(16, 60, default=26)  # Moving average period
high_offset = DecimalParameter(0.8, 1.1, default=0.985)  # Sell offset
sell_trigger = CategoricalParameter(['SMA', 'EMA'], default='EMA')  # MA type

# Protection parameters
pair_is_bad_1_threshold = DecimalParameter(0.0, 0.30, default=0.130)
pair_is_bad_2_threshold = DecimalParameter(0.0, 0.25, default=0.075)

VI. Risk Management Features​

6.1 Dual Trend Filtering​

The strategy requires both medium-term trend (EMA50 > EMA200) and long-term trend (price > EMA200) confirmation before considering a buy, significantly reducing counter-trend trading risk.

6.2 Dynamic "Bad Pair" Detection​

By monitoring price changes over the past 6-12 candles, identify crashing pairs and suspend buying:

pair_is_bad = (
    ((open.shift(12) - close) / close >= 0.130) |  # 12 candles drop >= 13%
    ((open.shift(6) - close) / close >= 0.075)      # 6 candles drop >= 7.5%
)

6.3 Smart Exit Rejection​

When an exit signal triggers, additionally check market momentum. If momentum remains strong, reject the exit and continue holding to maximize profit potential.

VII. Strategy Advantages and Limitations​

✅ Advantages​

  1. Rigorous Trend Confirmation: Dual EMA filtering ensures trading only in uptrends
  2. Crash Avoidance Mechanism: Bad pair detection prevents buying during extreme market conditions
  3. Complete Profit Protection: Trailing stop + smart exit rejection dual protection
  4. Large Optimization Space: Multiple parameters support Hyperopt optimization

⚠️ Limitations​

  1. Large Stop Loss Space: 23% stop loss may be too wide for conservative traders
  2. Average Performance in Sideways Markets: As a trend strategy, may experience frequent small losses during sideways movement
  3. Single Timeframe: Only uses 5-minute, lacking multi-timeframe confirmation
