BcmbigzV1: The "Sea King" Player in Bollinger Band World

Nickname: Sea King Strategy
Profession: Quant World's "Net-Casting Fisherman"
Timeframe: 5 minutes (entry) + 1 hour (confirmation)

1. What Is This Thing?​

Simply put, BcmbigzV1 is:

  • Wants to buy when seeing "oversold" — aggressive type
  • Frantically probes near lower Bollinger Band
  • 14 entry conditions take turns on duty, whichever is satisfied enters

Like a veteran squatting at a vegetable market, can't help but buy dips when seeing price fall to bottom of bag 🛒

One-Sentence Summary: "Dip-buying enthusiast" whose hands itch when seeing lower Bollinger Band

2. Core Config: Simply "Fast In Fast Out"​

Profit-Taking Rules (ROI Table)​

Holding 0-10 min: Make 3.8% and run
Holding 10-40 min: Make 2.8% is also okay
Holding 40-180 min: Make 1.5% makes do
Holding 180+ min: Make 1.8% let's leave

Translation: This strategy's core philosophy is "fast"! The faster you make money, the better. The longer the time, the more anxious to sell.

Stoploss Rules​

Hard stoploss: Disable default stoploss (-99%, basically equals none)
Actual stoploss: Custom stoploss logic
Trailing stop: Activate after profit exceeds 1%, stoploss line moves up 2.5%

Translation: Strategy doesn't set fixed stoploss, but has a 50-minute "observation period". Still losing after observation period? Then decide whether to stoploss based on situation.

3. 14 Entry Conditions: Sea King's "Concubine Selection" Standards​

This strategy's entry conditions can be called "quant world's sea king", enter if any of 14 conditions is satisfied, I've categorized them for you:

🎯 Category 1: RSI Oversold Type (Conditions 0, 3, 4, 8, 9)​

Core Logic: RSI below certain value means "cheap", buy!

In Plain English:

"RSI fell below 30? Buy when it breaks! Fell below 14? Close eyes and go all-in!"

Representative Conditions:

  • Condition 0: 5-minute RSI < 30 + Price above EMA200 + Still falling recently → "Trend up but short-term plummet, buy the dip!"
  • Condition 4: 1-hour RSI < 16.5 + Price at lower Bollinger Band → "Big cycle extremely oversold, high rebound probability!"

📉 Category 2: Lower Bollinger Band Type (Conditions 1, 2, 12)​

Core Logic: Buy when price approaches lower Bollinger Band

In Plain English:

"Price fell to lower Bollinger Band? Buy! Fell more? Even more certain!"

Representative Conditions:

  • Condition 1: Price < Lower Band × 0.989 + Bearish close → "Touched band and still bearish, high probability of rebound tomorrow"
  • Condition 2: Price < Lower Band × 0.982 → "Deeply broke below band, buy more aggressively!"

🔄 Category 3: MACD Momentum Type (Conditions 5, 6, 7, 10)​

Core Logic: MACD golden cross + low price = entry

In Plain English:

"MACD golden cross? Price still at bottom? This is the legendary 'golden pit'!"

Representative Conditions:

  • Condition 5: MACD fast line > slow line + difference big enough + price at lower band → "Momentum turned positive + low price, double insurance!"
  • Condition 10: 1-hour RSI < 35 + 1-hour price at lower band + MACD just golden crossed → "Big cycle oversold + momentum reversal, this is bottom signal!"

💰 Category 4: Capital Flow Type (Condition 11)​

Core Logic: CMF (capital flow) significantly outflowing + RSI oversold

In Plain English:

"Capital significantly outflowing? RSI still very low? This may be prelude to main force accumulation followed by rally!"

🎪 Category 5: Special Pattern Type (Condition 12)​

Core Logic: False breakout pattern

In Plain English:

"Price broke below lower band then recovered? This is false breakout! Buy during rebound!"

4. Protection: 14-Layer "Safety Net"​

Each entry condition has independent protection parameters, like giving each "concubine" an exclusive bodyguard:

Protection TypeFunctionPlain English
Volume Pump DetectionPrevent buying at pumpdump top"Volume exploded 2.5x in 48 hours? Don't buy, may be cutting leeks"
Volume Contraction DetectionConfirm bottom"Volume contracted to 1/3.8 of before? Shows selling exhausted"
1-hour RSI ConfirmationAvoid buying at ceiling"Can only buy if 1-hour RSI below 69, prevent buying at top"

Roast: 14 conditions with so many parameters, optimization will give you plenty to drink 😅

5. Exit Logic: 50-Minute Life-or-Death Line​

5.1 Custom Stoploss (Core)​

if holding time < 50 minutes:
    Don't actively stoploss, give market time to reverse

if holding time >= 50 minutes:
    if 1-hour RSI < 40:
        Continue holding, wait for rebound
    elif price above EMA200 and fell more than 2.5%:
        Stoploss 1%, admit judgment mistake
    elif fell more than 1.5%:
        Stoploss 1%, admit defeat

In Plain English:

  • First 50 minutes: Don't rush, give market time to catch breath
  • After 50 minutes:
    • RSI still very low? Then wait, don't stoploss at lowest point
    • Still falling? Then stoploss, admit this judgment was wrong

5.2 Trailing Stop​

Activate trailing stop after profit > 1%
Stoploss line follows price increase, keep 2.5% pullback room

In Plain English: After making money, strategy follows price up, if falls 2.5% automatically sell, protect profits.

6. This Strategy's "Personality"​

✅ Pros (Praise Session)​

  1. Rich Signals: 14 conditions, opportunity to enter no matter how market changes
  2. Dual Confirmation: 5-minute entry + 1-hour confirmation, reduce false signals
  3. Smart Time Stoploss: Not simple fixed stoploss, judges based on RSI
  4. Volume Filtering: pumpdump detection reduces probability of being deceived

⚠️ Cons (Roast Session)​

  1. Too Many Conditions: 14 conditions × multiple parameters, extremely high optimization difficulty
  2. High Trading Frequency: Many signals means may trade frequently, fees hurt
  3. Fixed Parameters: No adaptive capability, different markets may need manual adjustment
  4. Only Suitable for Bull Market: All conditions require price above EMA200, basically useless in bear market

7. When to Use It?​

Market EnvironmentRecommended ActionReason
Bull Market Pullback✅ Key UsePullback is entry opportunity
Range Upward✅ SuitableBuy when falling to lower band
Sideways Range⚠️ CautionMay frequently be stopped out
One-Sided Decline❌ Don't UseEMA200 condition not satisfied, basically no signals

8. Bottom Line: How Is This Strategy?​

One-Sentence Review​

"Many signals, mixed conditions, suitable for quantitative players with patience to tune parameters"

Who Should Use It?​

  • ✅ Players with quantitative experience
  • ✅ Willing to spend time optimizing parameters

  • ✅ Prefer short-term trading

Who Should NOT Use It?​

  • ❌ Newcomers pursuing simple strategies

My Recommendations​

  1. Run with default parameters for 2 weeks first: Don't rush to optimize, see performance first
  2. Monitor each condition's performance: Some conditions may be more reliable than others
  3. Set maximum position count: Suggest maximum 3, avoid over-diversification

9. What Markets Make Money?​

9.1 Core Logic: 14 "Fishing Nets"​

BcmbigzV1's profit philosophy: Cast many nets, surely can catch some fish.

14 entry conditions, each is a net. Some nets specialize in catching "RSI oversold", some specialize in "lower Bollinger Band", some specialize in "MACD golden cross".

No one can predict what opportunities market will give. But with many nets, one will always catch something.

9.2 Performance in Different Markets (Plain English Version)​

Market TypePerformance RatingPlain English Explanation
📈 Bull Market Pullback⭐⭐⭐⭐⭐Best environment, pullback is entry opportunity
🔄 Wide Range Oscillation⭐⭐⭐⭐☆Frequently triggers lower band conditions, can make money
📉 Continuous Decline⭐⭐☆☆☆Occasionally catches rebounds, but easily stopped out
⚡️ Surge-Plunge⭐☆☆☆☆pumpdump protection may fail, high risk

One-Sentence Summary: Most satisfying to use in bull market, can make do in range market, don't think about bear market and extreme situations.

10.3 Backtest vs Live Trading​

Backtest Performance: Usually looks very good, because historical data "perfectly fits"

Live Reality: May be quite different, because:

  • Slippage: Actual execution price 0.1%-0.5% worse than backtest
  • Liquidity: Small coins may not be able to buy
  • Emotions: Strategy won't panic, but you will

Recommended Process:

  1. Run simulated trading for 2 weeks first
  2. Watch trade records daily, understand strategy behavior
  3. Adjust parameters to comfortable range
  4. Small capital live test

Don't go all-in right away, even good strategies need breaking in!

11. Easter Egg: Strategy Author's "Little Thoughts"​

Looking carefully at code, you'll find some interesting things:

  1. Condition 2 Particularly Aggressive: Allows price to fall 1.8% below lower band

    "The harder it falls, the harder it rebounds" — author's gambling mentality

  2. RSI Threshold Distribution Very Wide: From 10 to 35 all present

    "Different degrees of oversold, different entry timing" — author wants to cover all oversold scenarios

  3. 50-Minute Stoploss Observation Period

    "Don't stoploss too early, may stoploss exactly at lowest point" — author deeply understands leek psychology

12. Last But Not Least​

One-Sentence Review​

"Many conditions, many signals, intermediate strategy requiring patience to debug"

Who Should Use It?​

  • ✅ Traders with some quantitative experience
  • ✅ Willing to spend time understanding and optimizing
  • ✅ Can accept more trade counts
  • ✅ Mainly do short-term trading

Who Should NOT Use It?​

  • ❌ Complete newcomers
  • ❌ Pursuing simple stability
  • ❌ Don't want frequent operations
  • ❌ Long-term investors

Manual Trader Recommendations​

If you trade manually, can borrow this strategy's thinking:

  • Focus on oversold opportunities near lower Bollinger Band
  • Use 1-hour RSI to confirm big trend
  • Set an "observation period", don't stoploss too fast
  • But manual trading hard to execute 14 conditions, suggest simplifying

13. ⚠️ Final Risk Reminder (Must Read This Section)​

Backtests Look Beautiful, Live Trading Requires Caution​

BcmbigzV1's historical backtest performance often looks very beautiful — but there's a trap:

14 conditions × multiple parameters, easily "fits" historical market conditions's optimal solution, but this doesn't mean future will definitely profit.

Simply put: Got full marks on historical exam, doesn't mean will do well on college entrance exam.

Hidden Risks of Complex Strategies​

In live trading, 14 entry conditions may lead to:

  • Overtrading: Too many signals, fees accumulate into mountain
  • Parameter Sensitivity: Slight threshold adjustment, results worlds apart
  • Hard to Attribute: Don't know which condition made money when winning, don't know why when losing

Signal Quality Varied​

Not all 14 conditions are good:

  • Some conditions may not trigger long-term
  • Some conditions have very low win rate after triggering
  • You need time to observe which conditions are reliable

My Recommendations (Real Talk)​

1. Run at least 2 weeks simulated trading, observe each condition's performance
2. Can consider disabling some conditions, keep most effective 5-7
3. Set reasonable maximum position count, don't exceed 3
4. Check trade records weekly, adjust timely when finding problems

Remember: No matter how good the strategy, market won't greet you when teaching you a lesson. Light position test, staying alive is most important! 🙏
