BigZ0407HO Strategy Analysis

I. Strategy Overview​

BigZ0407HO is the HyperOpt optimized version of BigZ0407, with deep parameter optimization and enhancements performed by developer ilya based on the original version. This strategy inherits the pursuit of low drawdown, while achieving a better balance between risk control and profit pursuit through optimized parameter configuration and more comprehensive sell protection mechanisms. The core improvements of the HO version lie in replacing traditional fixed ROI with a dynamic tiered take-profit system, and significantly enhancing protection capabilities against extreme market conditions.

Optimization MethodHyperOpt parameter optimization

From a technical implementation perspective, BigZ0407HO has undergone comprehensive parameter optimization based on BigZ0407. The original version uses a fixed ROI ladder, while the HO version relies entirely on a custom dynamic exit system (custom_exit), capable of intelligently deciding exit timing based on multiple dimensional factors including position's real-time profit/loss status, RSI levels, EMA200 position, etc. This design enables the strategy to better adapt to market dynamic changes, flexibly adjusting behavioral strategies in different market environments.

The strategy's design philosophy remains "survival first" — in this high-volatility cryptocurrency market, first ensure capital safety, then pursue stable profits. The HO version's improvements enable it to further enhance profitability while maintaining low drawdown characteristics, with particularly outstanding performance in oscillating market environments.

II. Strategy Configuration Analysis​

BigZ0407HO's configuration parameters have been significantly improved compared to the original version through HyperOpt optimization. The strategy's parameter system can be divided into the following main categories: basic operation configuration, entry condition configuration, dynamic exit configuration, and risk protection parameters.

2.1 Basic Operation Configuration​

The strategy's timeframe settings remain unchanged: main cycle is 5 minutes, information cycle is 1 hour. This dual-timeframe design enables the strategy to simultaneously capture short-term trading opportunities and filter long-term trend noise. The process_only_new_candles parameter is set to True, ensuring the strategy only calculates signals when new candles form, which both improves calculation efficiency and avoids the trouble of duplicate signals. startup_candle_count is set to 200, which is the minimum historical data volume required for calculating various technical indicators.

Order type configuration uses limit orders as the default order placement method, which can reduce slippage costs to some extent. Stoploss orders use market orders to ensure quick execution during severe market volatility. stoploss_on_exchange is set to False, indicating stoploss logic is controlled by the strategy itself, providing greater flexibility and customization space.

2.2 Optimized Entry Conditions​

The HO version has undergone careful parameter optimization in entry conditions. The strategy retains 12 entry conditions (buy_condition_0 to buy_condition_11), each having undergone HyperOpt's automated optimization testing. Compared to the original version, the HO version's parameter changes are mainly reflected in the following dimensions:

RSI threshold optimization is one of the key upgrades in this version. The RSI thresholds used by various conditions in the original version were relatively conservative, while the HO version has made more aggressive adjustments based on historical data. For example, RSI thresholds for certain entry conditions have been lowered from the original 30 to lower values, enabling the strategy to enter at more oversold states, thereby obtaining better price advantages. Bollinger Band related parameters have undergone similar optimization, enabling the strategy to capture entry opportunities closer to wave bottoms.

Volume filter parameters have also been optimized and adjusted. The HO version is more sensitive to volume contraction judgments, helping filter out false signals that may exist due to abnormal volume expansion. By adjusting volume_drop and volume_pump series parameters, the strategy can more accurately identify changes in market activity.

2.3 Dynamic Exit Configuration​

This is the most important improvement of the HO version relative to the original version. The original version uses traditional minimal_roi configuration, while the HO version relies entirely on a custom dynamic exit system (custom_exit) to implement dynamic take-profit. This design enables exit decisions to consider more market factors, not just relying on holding time.

The core of the dynamic exit system is the tiered take-profit mechanism. The strategy defines 12 levels of take-profit conditions (signal_profit_0 to signal_profit_11), each corresponding to different profit ranges and RSI thresholds. Taking signal_profit_11 as an example, exit is triggered when profit exceeds 20% and RSI is below 34. This tiered design enables the strategy to dynamically adjust exit sensitivity based on profit level — the more profit, the more sensitive the exit, helping lock in more profits at high levels.

Additionally, the strategy has designed dedicated exit conditions for situations where price is below EMA200 (signal_profit_u_0 to signal_profit_u_11). These conditions add the requirement that closing price must be below EMA200 on top of standard take-profit conditions, ensuring more aggressive profit protection during downtrends.

2.4 Trailing Stop Configuration​

Trailing stop configuration remains consistent with the original version: trailing_stop set to True, trailing_stop_positive set to 0.01 (1%), trailing_stop_positive_offset set to 0.025 (2.5%). This means when position profit exceeds 1%, the system continuously records the highest price point, automatically triggering take-profit when price falls 2.5% from the highest point.

The unique aspect of the HO version lies in organically combining trailing stop with the custom exit system. When trailing stop triggers, it makes joint judgments with conditions in custom_exit, only executing exits when specific RSI conditions are met. This design avoids the problem of trailing stop being easily triggered by short-term volatility, while ensuring timely exits when clear reversal signals appear.

III. Entry Conditions Details​

BigZ0407HO strategy's entry logic has undergone parameter optimization based on BigZ0407, with 12 entry conditions targeting different market patterns and technical indicator combinations. The following will analyze the specific trigger mechanisms and optimized parameter changes for each entry condition one by one.

3.1 Condition 0: RSI Oversold Rebound Entry​

Entry condition 0 is a typical RSI oversold rebound strategy, with core logic being to buy when the market is short-term oversold, then sell after waiting for technical rebounds. Trigger conditions include: closing price above 200-day EMA (ensuring long-term trend upward), 5-minute RSI below optimized threshold (lower than original version), 1-hour RSI also in oversold region. Additionally requires meeting volume contraction conditions, meaning current volume significantly below long-term average levels.

The core concept of this condition is buying quality assets at favorable prices during short-term market oversold conditions, then quickly taking profits after technical rebounds. Optimized parameters enable the strategy to enter at more oversold states, thereby obtaining better safety margins.

3.2 Condition 1: Bollinger Band Lower Rail Entry​

Condition 1 requires price above both 200-day EMA and 1-hour EMA, while closing price near Bollinger Band lower rail. Optimized parameters enable the strategy to capture entry opportunities closer to Bollinger Band lower rail. Additionally, this condition requires 1-hour RSI in reasonable range, candle pattern as declining candle (opening price greater than closing price), and volume showing specific contraction patterns.

This entry pattern captures rebound opportunities when price finds support at Bollinger Band lower rail. Bollinger Band lower rail is typically viewed as strong support, when price touches here technical rebounds often occur. Optimized parameters enable the strategy to enter at more precise positions, thereby improving win probability.

3.3 Condition 2: Bollinger Band Lower Rail Safe Entry​

Condition 2 is similar to condition 1, but doesn't强制 require 1-hour RSI below specific values, only needing closing price near Bollinger Band lower rail. This design makes the condition more widely applicable, able to capture more oversold rebound opportunities. Volume conditions similarly require contraction patterns, meaning current volume significantly below previous candle.

3.4 Condition 3: Oversold Entry Above 1-Hour EMA​

Condition 3 is an entry strategy combining long and short-term trends. It requires price above 1-hour 200-day EMA (ensuring long-term trend upward) but below 5-minute Bollinger Band lower rail (short-term oversold), while 5-minute RSI extremely low. Volume conditions similarly require contraction patterns.

The uniqueness of this condition lies in simultaneously considering long-term trend direction (1-hour EMA) and short-term oversold signals (5-minute RSI and Bollinger Band position). This multi-timeframe analysis method ensures entry signals align with long-term trend direction, avoiding risks of counter-trend operations.

3.5 Conditions 4-6: RSI and MACD Combination Entry​

Condition 4 requires 1-hour RSI extremely low and price at Bollinger Band lower rail, this is a pure oversold strategy. Conditions 5 and 6 combine MACD indicators, requiring MACD's fast line above slow line, with sufficient difference between the two lines. Condition 5 also requires closing price below Bollinger Band lower rail, to capture deeper oversold opportunities.

These conditions aim to capture entry opportunities accompanying oversold patterns after MACD golden crosses. MACD golden cross is viewed as signal of short-term momentum turning from weak to strong, while oversold patterns provide better entry prices. The combination can effectively filter out those rebounds with insufficient momentum.

3.6 Conditions 7-9: Multi-Indicator Resonance Entry​

Conditions 7-9 further combine more technical indicators, forming multi-indicator resonance entry strategies. Condition 7 requires 1-hour RSI extremely low, MACD showing golden cross pattern, while volume contracts. This condition captures opportunities where multiple technical indicators simultaneously send buy signals, although trigger frequency is lower, signal reliability is higher.

Condition 8 is a pure RSI oversold strategy, combining 1-hour RSI and 5-minute RSI. Condition 9 adds volume conditions to condition 8, requiring volume to expand earlier then contract, this pattern usually indicates selling pressure has been released.

3.7 Condition 10: 1-Hour Oversold Rebound Entry​

Condition 10 is a 1-hour and 5-minute combined oversold rebound strategy. It requires 1-hour RSI below specific thresholds, while 1-hour closing price below 1-hour Bollinger Band lower rail, MACD histogram showing positive turn from negative, 5-minute RSI below specific values. This condition captures 1-hour level oversold conditions accompanied by short-term momentum strengthening.

3.8 Conditions 11-12: Special Pattern Entry​

Conditions 11 and 12 are more complex entry conditions. Condition 11 requires closing price above Bollinger Band middle rail but previous candle below middle rail, while MACD histogram remains continuously positive. Condition 12 is a "false breakout" entry pattern, requiring price to first break above Bollinger Band upper rail then fall back near lower rail. These conditions capture reversal patterns and pullback opportunities after consolidation breakouts.

IV. Exit Conditions Details​

BigZ0407HO strategy's exit logic is the most important upgrade point relative to the original version. Unlike traditional fixed ROI, the HO version adopts a completely dynamic custom exit system (custom_exit), capable of intelligently deciding exit timing based on position's real-time status and market environment.

4.1 Tiered Dynamic Take-Profit Mechanism​

The strategy defines 12 levels of take-profit conditions (signal_profit_0 to signal_profit_11), each corresponding to different profit ranges and RSI thresholds. This tiered design is the HO version's core innovation, implementing "the more profit, the more sensitive the exit" dynamic adjustment.

Taking signal_profit_11 as an example, exit is triggered when profit exceeds 20% and RSI below 34. This means the strategy becomes more sensitive when obtaining larger profit amplitudes, slight RSI increases trigger exits, helping lock in profits at high levels. When profits are smaller, the strategy gives positions more room to rebound, reducing the possibility of being "shaken out."

signal_profit_1 corresponds to 1%-2% profit range, RSI threshold similarly low. This design ensures that even with smaller profits, the strategy will timely exit when clear reversal signals appear, avoiding losses from expecting larger rebounds.

4.2 EMA200 Below Special Handling​

The strategy designs dedicated exit conditions for situations where price is below EMA200 (signal_profit_u_0 to signal_profit_u_11). These conditions add the requirement that closing price must be below EMA200 on top of standard take-profit conditions.

When price falls below EMA200, it means the market may have entered a downtrend. At this time even if profit amplitude is not large, exits are triggered as long as RSI reaches corresponding thresholds. This design helps protect existing profits during downtrends, avoiding profit giveback from expecting rebounds.

4.3 Pump Protection Mechanism​

For "pump" patterns common in cryptocurrency markets (i.e., short-term sharp price increases followed by rapid declines), the strategy designs sell protection mechanisms across three time dimensions: 48 hours, 36 hours, and 24 hours. These mechanisms identify abnormal volatility by detecting price volatility (hl_pct_change and oc_pct_change).

When abnormal volatility is detected, the strategy automatically enables enhanced exit conditions. These conditions adopt more aggressive exit strategies after detecting large increases, regardless of current profit level, exits are triggered as long as RSI reaches thresholds. This design can effectively avoid investors suffering huge losses after entering at "pump" peaks.

4.4 Trend Reversal Detection Exit​

The strategy contains multiple trend reversal detection exit conditions. The sma_200_dec_20 condition detects whether 200-day SMA is in declining state, triggering exits when SMA declining and profit in specific ranges. This condition can effectively identify long-term trend changes, helping the strategy exit before trend reversals.

sell_trail_ prefixed conditions combine trailing take-profit concepts. Triggered when profit reaches certain levels and falls specific proportions from highest points, these conditions complement the strategy's trailing stop system, further enhancing profit protection capabilities.

4.5 Recovery Exit Mechanism​

For positions already experiencing significant losses, the strategy designs recovery exit mechanisms (signal_profit_r_1 and signal_profit_r_2). These conditions trigger exits as long as slight profits occur and RSI meets conditions after position losses exceed specific proportions.

This mechanism aims to minimize losses as much as possible, avoiding long-term holding of continuously declining assets. Although this design may lead to exiting with small losses in certain situations, it effectively controls maximum drawdown, aligning with the strategy's "survival first" core philosophy.

4.6 Long-Term Position Special Handling​

The strategy also considers long-term position situations. The sell_custom_long_profit_1 condition triggers exits for trades held over 900 minutes (approximately 15 hours) with profits in the 3%-4% range. This ensures that even without obvious market reversal signals, long-term positions won't be held indefinitely.

V. Technical Indicator System​

BigZ0407HO strategy uses rich technical indicators to build its trading decision system, covering multiple dimensions including trend judgment, overbought/oversold analysis, volume analysis, and volatility analysis.

5.1 Trend Indicators​

The strategy primarily uses Exponential Moving Averages (EMA) to judge market trends. Key trend judgment indicators include: ema_12 (12-period EMA), ema_26 (26-period EMA, used for MACD calculation), ema_50 (50-period EMA), ema_100 (100-period EMA), and ema_200 (200-period EMA). Among these, the 200-day EMA serves as the core trend dividing line — when price above 200-day EMA considered bull market pattern, below considered bear market pattern.

Additionally, the strategy uses Simple Moving Averages (SMA), particularly sma_200 for detecting long-term trend direction. sma_200_dec_20 and sma_200_dec_24 detect whether SMA200 has been continuously declining over past 20 and 24 periods respectively, used to judge whether market is in downtrend.

5.2 Overbought/Oversold Indicators​

Relative Strength Index (RSI) is the most important overbought/oversold indicator in the strategy. The strategy simultaneously calculates 5-minute timeframe RSI and 1-hour timeframe RSI (rsi_1h), comprehensively using RSI values from both time periods in entry and exit conditions. Generally, 5-minute RSI judges short-term oversold opportunities, while 1-hour RSI filters short-term signals opposite to long-term trends.

The optimized HO version has adjusted RSI parameters, enabling various conditions to more flexibly adapt to different market environments. RSI thresholds for some entry conditions have been lowered, enabling the strategy to enter at more oversold states, obtaining better price advantages.

Bollinger Bands are another important overbought/oversold tool. The strategy uses two Bollinger Band settings: 20-period and 40-period. Bollinger Band lower rail (bb_lowerband) typically viewed as support, while upper rail (bb_upperband) viewed as resistance. When price touches lower rail often indicates oversold, while touching upper rail may indicate overbought.

5.3 Momentum Indicators​

MACD (Moving Average Convergence Divergence) is the strategy's primary momentum indicator. The strategy uses standard settings of 12-period fast line, 26-period slow line, and 9-period signal line. MACD histogram (hist) positive/negative changes used as signals for momentum transitions — when histogram turns from negative to positive, indicates short-term momentum strengthening.

Elliot Wave Oscillator (EWO) is another momentum indicator, calculating percentage difference between 5-period EMA and 35-period EMA relative to closing price. EWO helps identify trend strength and potential reversal points.

5.4 Volume Indicators​

The strategy uses volume moving averages (volume_mean_slow and volume_mean_4) to evaluate current volume levels. volume_mean_slow uses 48-period calculation, representing long-term average volume. When current volume significantly below long-term average, typically viewed as signal of decreased market activity.

The HO version has optimized volume filter parameters, enabling the strategy to more accurately identify abnormal volume changes. volume_drop series parameters used to detect volume contraction patterns, while volume_pump series parameters used to identify abnormal volume expansion.

5.5 Volatility Indicators​

The strategy uses multiple custom volatility indicators to evaluate market state. range_percent_change function calculates price change percentage over specific periods, used to detect abnormal volatility. top_percent_change function calculates percentage change between current closing price and historical highest opening price, used to judge price position relative to recent highs.

These volatility indicators are primarily used to identify "pump" patterns (sell_pump_48_1, sell_pump_36_1, sell_pump_24_1, etc.), when abnormal volatility detected, strategy enables additional protective exit conditions.

VI. Strategy Pros & Cons​

6.1 Strategy Advantages​

Excellent Drawdown Control: BigZ0407HO's most significant advantage lies in its exceptional drawdown control capability. The strategy's core philosophy is "keep drawdown as low as possible," the combination of multiple stop-loss mechanisms (custom stop-loss, trailing stop, recovery stop-loss) enables the strategy to react quickly during unfavorable markets and cut losses.

Parameter Optimization Advantage: As a HyperOpt optimized version, HO version's parameters have been tested and validated through大量 historical data. Compared to the original version, the HO version can better adapt to different market environments, with higher signal accuracy.

Rich and Diverse Signals: The strategy provides 12 different entry conditions, covering various market patterns including oversold rebounds, breakout pullbacks, and trend pullbacks. This diversity enables the strategy to find trading opportunities in different market environments.

Intelligent Exit Mechanism: The strategy's custom_exit system is its most complex and powerful part. The combination of tiered take-profit, trend reversal detection, pump protection, recovery mechanisms, and various other exit logics enables the strategy to adopt optimal exit strategies based on different market conditions.

Multi-Timeframe Analysis: By combining information from both 5-minute and 1-hour timeframes, the strategy can more comprehensively understand market state. 1-hour level indicators judge long-term trends and filter false signals, while 5-minute level indicators precisely grasp entry timing.

6.2 Strategy Limitations​

Large Number of Parameters: The strategy has hundreds of configurable parameters, although most have been optimized, such a large parameter count may be difficult for beginners to understand and adjust. Incorrect parameter settings may lead to significant strategy performance declines.

Potentially High Trading Frequency: Due to having 12 entry conditions with most enabled by default, the strategy may generate many trading signals during high market volatility. High trading frequency means higher trading costs (fees, slippage), which may erode strategy profitability.

May Perform Poorly in One-Sided Uptrends: The strategy's oversold rebound design makes it more suitable for oscillating markets and rebound patterns after declines. In sustained bull markets, the strategy may miss more profits due to premature exits.

Sensitive to Market Environment: Multiple conditions in the strategy are designed for specific market patterns. When market characteristics undergo fundamental changes (such as transitioning from oscillating to one-sided trends), the strategy may require parameter or condition setting readjustments.

Maintenance Difficulty from Complexity: The strategy code contains大量 technical indicator calculations and condition judgments. This complexity makes strategy debugging and maintenance relatively difficult, requiring experienced traders to effectively optimize and adjust.

VII. Applicable Scenarios​

Oscillating Market Environment: BigZ0407HO is most suitable for oscillating markets. When prices fluctuate within a relatively fixed range, the strategy's oversold buying and quick profit-taking logic can effectively capture range volatility profits. In this environment, the strategy's multiple entry conditions can trigger frequently, while the exit mechanism can timely exit when prices rebound to reasonable levels.

High Volatility Markets: The strategy's pump protection mechanism and volatility detection functions enable it to adapt to high volatility markets. When abnormal volatility occurs, the strategy can automatically adjust exit strategies, protecting acquired profits during volatility. This is particularly important for cryptocurrency markets with high volatility.

Rebound Opportunities After Downtrends: The strategy's core philosophy is "buy after declines," therefore it often performs well in technical rebound opportunities after prices experience significant declines. When markets begin recovering from lows, oversold RSI and prices touching Bollinger Band lower rails provide ideal entry signals for the strategy.

7.2 Scenarios Requiring Caution​

Strong One-Sided Uptrends: In sustained bull markets, the strategy's exit mechanism may be too conservative, leading to premature exits and missing larger gains. If the market is in a clear uptrend, consider disabling some strict exit conditions or adjusting take-profit parameters.

Prolonged Sideways Consolidation: When markets remain sideways for extended periods, although the strategy's entry conditions may trigger frequently, each rebound amplitude may be limited. Frequent small profits may难以 cover trading costs, leading to poor overall performance.

Low Liquidity Markets: Multiple conditions in the strategy rely on volume analysis. In low liquidity markets, volume signals may be distorted, potentially leading to false entry signals or unnecessary trades.

7.3 Use with Other Tools​

It's recommended to use BigZ0407HO with other risk management tools. For example, overall fund management rules can be set to limit the strategy's maximum exposure on single tokens. Daily or weekly trading frequency limits can also be set to avoid overtrading.

Additionally, regularly reviewing strategy performance and adjusting parameters based on market conditions is necessary. As market characteristics change, certain entry conditions may need to be enabled or disabled, or take-profit/stop-loss parameters adjusted.

VIII. Parameter Optimization​

8.1 Default Parameter Philosophy​

The strategy's default parameters have been carefully optimized through HyperOpt. Most parameters balance signal frequency and quality, avoiding excessive trading while ensuring sufficient opportunities. Unless you have specific understanding of market characteristics, it's recommended to use default parameters.

8.2 Optimization Directions​

If optimization is needed, the following directions can be considered:

RSI Threshold Adjustment: Adjust RSI thresholds based on market volatility. In high volatility markets, RSI thresholds can be appropriately lowered to filter false signals; in low volatility markets, thresholds can be raised to increase signal frequency.

Bollinger Band Parameter Adjustment: Adjust Bollinger Band period and standard deviation parameters based on market characteristics. Longer periods suitable for long-term trends, shorter periods suitable for short-term volatility.

Volume Condition Adjustment: Adjust volume condition thresholds based on trading pair liquidity. For high liquidity pairs, volume conditions can be relaxed; for low liquidity pairs, volume conditions should be stricter.

8.3 Optimization Precautions​

When optimizing parameters, the following principles should be followed: change only one parameter at a time; conduct sufficient historical backtesting after changes; record the effects of each change; retain original parameter settings as reference. Additionally, most parameters can be systematically optimized through Freqtrade's optimization function, but the optimization process requires大量 historical data and time investment.

IX. Live Trading Notes​

9.1 Preparation Before Live Trading​

Before deploying the strategy for live trading, sufficient backtesting should be conducted. Backtesting should use long-term historical data, preferably covering different market environments (bull markets, bear markets, oscillating markets). Only strategies performing well in backtesting should be deployed for live trading.

Additionally, paper trading should be conducted before live trading. Paper trading can verify whether the strategy operates normally in real-market environments and whether there are any technical issues (such as data delays, order execution problems, etc.).

9.2 Monitoring During Live Trading​

Even after the strategy is deployed and operating normally, continuous monitoring remains necessary. The strategy's exit mechanism relies on complex market state judgments and may produce unexpected behavior in certain edge cases. Regularly checking strategy trading logs, profit/loss situations, and position status can timely detect and correct problems.

It's recommended to set alert mechanisms to timely notify when the strategy exhibits abnormal behavior (such as sudden changes in trading frequency, large single-trade losses, consecutive losses, etc.). These alerts can help investors take action before problems escalate.

9.3 Parameter Adjustment During Live Trading​

During live trading, parameters may need to be adjusted based on market environment changes. For example, during high volatility periods, some entry conditions can be disabled to reduce trading frequency; during low volatility periods, take-profit parameters can be adjusted to increase profit targets.

However, parameter adjustments should be cautious, avoiding frequent changes. Each adjustment should be based on sufficient market observation and data analysis, not emotional decisions.

X. Summary​

BigZ0407HO is a well-designed, comprehensive cryptocurrency trading strategy, serving as the HyperOpt optimized version of BigZ0407. Its core philosophy centers on controlling drawdown to minimum levels through multiple protection mechanisms while capturing rebound opportunities after market declines. The strategy's 12 entry conditions and complex custom exit system enable it to adapt to various market environments.

From a technical implementation perspective, the strategy comprehensively uses classic technical indicators such as Bollinger Bands, RSI, MACD, and EMA, and innovatively combines multi-timeframe analysis, volatility detection, volume analysis, and other methods. This complex technical system provides the strategy with comprehensive market insight capabilities, but also means higher understanding and maintenance thresholds.

As an optimized version, the HO version has significant improvements compared to the original version. Parameter optimization enables the strategy to more accurately capture trading opportunities, while the completely dynamic custom exit system provides more flexible and intelligent profit protection mechanisms. The addition of tiered take-profit, EMA200 below special handling, pump protection, and other functions enables the strategy to have better performance in various market environments.

However, investors should also clearly recognize the strategy's limitations. The large number of parameters may bring over-optimization risks, complex logic increases understanding and maintenance difficulty, and the strategy's oversold rebound characteristics determine its performance in one-sided uptrends may not be as good as in oscillating markets.

Overall, BigZ0407HO is a strategy suitable for investors with certain quantitative trading experience. For beginners, it's recommended to start with simpler strategies, and only attempt to use or modify BigZ0407HO after accumulating sufficient experience. During use, sufficient backtesting should be conducted, parameters should be adjusted cautiously, and continuous monitoring should be maintained to ensure effective strategy operation.
