SMAOffsetV2 Strategy Analysis

Strategy ID: #366 (Batch 361-370 of 465 strategies)
Strategy Type: SMA Offset + EMA Trend Filter + Dynamic Stop Loss
Timeframe: 5 minutes (5m) + 1 hour informative layer

---

1. Strategy Overview

SMAOffsetV2 is a trend-following strategy based on Simple Moving Average offset (SMA Offset), with trend detection and custom stop loss mechanisms added on top of the original SMAOffset. This strategy uses EMA fast/slow lines (20/25) to determine trend direction, only looking for SMA offset buying opportunities in uptrends, while controlling risk through a dynamic stop loss mechanism.

The strategy design philosophy is simple and clear: Only buy when trend is upward, enter when price pulls back below the moving average, exit when price returns above the moving average or trend reverses.

Core Features

Feature	Description
Buy Condition	1 buy signal (trend filter + SMA offset)
Sell Condition	1 sell signal (two sub-conditions with OR logic)
Protection Mechanism	Dynamic stop loss (time + loss dual condition trigger)
Timeframe	5m (main) + 1h (informative layer trend judgment)
Dependencies	talib, pandas, freqtrade.persistence

2. Strategy Configuration Analysis

2.1 Basic Risk Parameters

# ROI exit table
minimal_roi = {
    "0": 1,    # 100% (almost never uses ROI)
}

# Stop loss setting
stoploss = -0.20  # Fixed stop loss -20%

# Custom stop loss
use_custom_stoploss = True

Design Philosophy:

• ROI set to 100%, essentially abandoning ROI take-profit, relying on sell signals and stop loss
• 20% fixed stop loss as the last line of defense
• Custom stop loss function provides more flexible risk control

2.2 Order Type Configuration

use_sell_signal = True      # Use sell signal
sell_profit_only = True     # Use sell signal only when profitable
process_only_new_candles = True  # Process only on new candles

3. Buy Condition Detailed Analysis

3.1 Trend Filter Mechanism

The strategy uses 1-hour timeframe EMA to determine trend:

# 1-hour EMA indicators
dataframe['ema_fast'] = ta.EMA(dataframe, timeperiod=20)
dataframe['ema_slow'] = ta.EMA(dataframe, timeperiod=25)

# Trend judgment
dataframe['go_long'] = (
    (dataframe['ema_fast'] > dataframe['ema_slow'])
).astype('int') * 2

Logic Interpretation:

• go_long = 2: EMA fast line > EMA slow line, uptrend
• go_long = 0: EMA fast line ≤ EMA slow line, downtrend

3.2 Buy Condition

# Trigger conditions
- go_long > 0 (1-hour uptrend)
- Close price < sma_30_offset (price below SMA(20) × 0.96)
- Volume > 0

Detailed Analysis:

Condition	Parameter	Description
Trend filter	EMA(20) > EMA(25)	Only buy in 1-hour uptrend
SMA offset	SMA(20) × 0.96	Price 4% below moving average
Volume	> 0	Trading activity exists

Design Intent:

• Through 1-hour trend filter, avoid bottom-fishing in downtrend
• 4% offset amplitude is relatively large, ensuring sufficient price discount
• Simple and clear, one condition to enter

4. Sell Logic Detailed Analysis

4.1 Sell Conditions (Two Sub-conditions with OR Logic)

# Sell signal
(
    (go_long == 0)           # Trend reversal (sub-condition 1)
    |
    (close > sma_30_offset_pos)  # Price breaks above upper offset (sub-condition 2)
)
&
(volume > 0)

Sub-condition Details:

Sub-condition	Trigger Logic	Description
#1 Trend reversal	go_long == 0	1-hour EMA death cross, trend turns down
#2 Price breakout	close > SMA(20) × 1.012	Price 1.2% above moving average

Logic Interpretation:

• Trend reversal: 1-hour EMA fast line crosses below slow line, indicating possible trend reversal
• Price breakout: Price rises to 1.2% above moving average, reaching profit target

4.2 Dynamic Stop Loss Mechanism

The strategy implements a custom stop loss function, providing intelligent risk control:

def custom_stoploss(self, pair: str, trade: 'Trade', current_time: datetime,
                    current_rate: float, current_profit: float, **kwargs) -> float:

    # Condition: Held for more than 40 minutes + loss exceeds 10%
    if current_time - timedelta(minutes=40) > trade.open_date_utc and current_profit < -0.1:
        return -0.01  # Tighten stop loss to -1%

    return -0.99  # Default: almost never triggers stop loss

Working Mechanism:

• Default state: Stop loss -99% (almost never triggers)
• Trigger condition: Held > 40 minutes AND loss > 10%
• After trigger: Stop loss tightens to -1%, quick stop loss

Design Intent:

• Give the strategy enough time to "self-rescue", avoid premature stop loss
• If still losing more than 10% after 40 minutes, acknowledge judgment error and stop quickly

5. Technical Indicator System

5.1 Core Indicators

Indicator Category	Specific Indicator	Parameters	Purpose
Trend	EMA	20/25 periods	1-hour trend judgment
Trend	SMA	20 periods	Price offset reference baseline
Volume	Volume	-	Liquidity confirmation

5.2 Informative Timeframe Indicators (1h)

The strategy uses 1 hour as the informative layer, providing higher-dimensional trend judgment:

# 1-hour timeframe
informative_timeframe = '1h'

# Informative layer indicators
ema_fast = EMA(20)  # Fast line
ema_slow = EMA(25)  # Slow line
go_long = (ema_fast > ema_slow) * 2  # Trend signal

Workflow:

1. Get 1-hour candlestick data
2. Calculate EMA(20) and EMA(25)
3. Determine if fast line is above slow line
4. Merge trend signal into 5-minute data

6. Risk Management Features

6.1 Dynamic Stop Loss System

The strategy adopts intelligent dynamic stop loss, different from traditional fixed stop loss:

Stop Loss Type	Trigger Condition	Stop Loss Value	Description
Initial state	Any situation	-99%	Almost never triggers
Dynamic tightening	Held > 40 minutes AND loss > 10%	-1%	Quick stop loss

Advantages:

• Avoid being stopped out by normal volatility
• Give strategy enough time to recover
• Quick stop loss after confirming failure

6.2 Trend Filter Protection

• Only buy in 1-hour uptrend
• Immediately sell when trend reverses
• Avoid counter-trend trading

6.3 Profit Protection

sell_profit_only = True     # Use sell signal only when profitable

This setting ensures sell signals don't trigger at a loss, avoiding selling during floating losses.

7. Strategy Advantages and Limitations

✅ Advantages

1. Clean Logic: One buy condition, two sell conditions, clear and easy to understand
2. Trend Filter: Uses 1-hour EMA to determine trend, avoids counter-trend trading
3. Dynamic Stop Loss: Gives strategy recovery time, quick stop when failed
4. Small Code Size: Easy to understand and further develop

⚠️ Limitations

1. Fixed Parameters: Buy parameters are hardcoded, not as flexible as HyperOpt versions
2. Large Offset: 4% offset may miss some opportunities
3. No Trailing Stop: No trailing take-profit mechanism, may "ride the rollercoaster"
4. Trend Dependent: May perform poorly in ranging markets

8. Applicable Scenario Recommendations

Market Environment	Recommended Configuration	Description
Uptrend	Default configuration	Trend filter ensures trend-following trading
Ranging market	Not recommended	Frequent EMA crossovers may cause repeated stop losses
Downtrend	Not recommended	Trend filter will block buying
High volatility	Increase offset parameters	Avoid being triggered by normal volatility

---

9. Applicable Market Environment Detailed

SMAOffsetV2 is a simplified version of the SMA Offset series, focusing on trend following. Based on its code architecture, it is most suitable for markets with clear trends, and performs poorly in sideways oscillation.

9.1 Strategy Core Logic

• Trend Filter: Only buy when 1-hour EMA is in golden cross state
• Price Offset Entry: Enter when price is 4% below SMA
• Dual Exit: Exit when trend reverses or price breaks out

9.2 Performance in Different Market Environments

Market Type	Performance Rating	Reason Analysis
📈 Slow bull trend	⭐⭐⭐⭐⭐	Trend filter works, many pullback buying opportunities
🔄 Sideways oscillation	⭐⭐☆☆☆	EMA frequently crosses, trend judgment fails
📉 One-sided decline	⭐⭐⭐⭐☆	Trend filter blocks buying, stay out and avoid risk
⚡️ Severe volatility	⭐⭐⭐☆☆	Offset amplitude may be penetrated

9.3 Key Configuration Recommendations

Configuration Item	Recommended Value	Description
Trading pair	Major coins/stablecoins	Clear trend, good liquidity
Stop loss	Keep -20%	As last line of defense
Dynamic stop loss time	40 minutes	Can adjust based on trading pair

10.3 Difference Between Backtesting and Live Trading

• Advantage: Simple logic, small difference between backtesting and live trading
• Note: Dynamic stop loss time judgment may have slight differences in live trading
• Recommendation: Suitable as a starting point for learning strategy framework

10.4 Suggestions for Manual Traders

If you want to manually use the logic of this strategy:

1. Use 1-hour EMA(20) and EMA(25) to determine trend
2. In uptrend, wait for price to pull back 4% below 20 SMA
3. Set 20% fixed stop loss
4. When 1-hour EMA death cross or price rises 1.2% above SMA, sell
