Strategy Type: Session Trading / London Session Ultimate Version
Timeframe: 15 Minutes (15m)

I. Strategy Overview​

LondiniumV4 is the fourth and ultimate version of the Londinium strategy series. This strategy adds more verification mechanisms, more complete parameter configurations, and stricter signal filtering on top of previous versions, making it the culmination of the Londinium series.

The name "V4" stands for Version 4, indicating this is the ultimate version of the Londinium series, optimized through multiple iterations.

Core Characteristics​

AttributeDescription

II. Strategy Configuration Analysis​

2.1 Base Risk Parameters​

# ROI Exit Table
minimal_roi = {
    "0": 0.12,
    "30": 0.08,
    "60": 0.04,
    "120": 0
}

# Stop Loss Settings
stoploss = -0.10

# Trailing Stop
trailing_stop = True
trailing_stop_positive = 0.035
trailing_stop_positive_offset = 0.04

Design Philosophy:

  • Highest Take-Profit: 12% initial target, ultimate version pursues higher returns
  • Standard Stop Loss: -10% stop loss magnitude
  • Trailing Stop: Enabled to lock in more profits

2.2 Session Configuration Parameters​

# London Session Configuration
london_start = 8      # Start at UTC 8:00
london_end = 16       # End at UTC 16:00

# Enhanced Parameters
session_strength_threshold = 0.7  # Session strength threshold
volume_spike_threshold = 1.5      # Volume spike threshold

III. Entry Conditions Details​

3.1 Three Sets of Entry Conditions​

V4 adds a third entry condition, forming a more complete signal system:

Condition #1: London Open Breakout​

Logic:

  • A price range forms after London opens
  • Price breaks through the upper or lower boundary of the range
  • Volume expands to confirm
# Logic Judgment
london_open = current_hour == 8
range_breakout = close > session_high
volume_confirm = volume > volume_ma * 1.5

Condition #2: Trend Continuation​

Logic:

  • A clear trend forms during the London session
  • Price pulls back to support
  • Trend continuation signal confirmed
# Logic Judgment
trend_established = price > session_open * 1.02
pullback = close <= session_high * 0.98
trend_continue = macd > 0

Condition #3: Volatility Breakout​

Logic:

  • London session volatility breaks through threshold
  • Price breaks through in the direction of volatility
  • Multi-dimensional confirmation signal
# Logic Judgment
volatility_break = atr > atr_ma * 1.2
price_break = close > bb_upper
momentum_confirm = rsi > 50

IV. Exit Logic Details​

4.1 Multi-Layer Take-Profit System​

Take-Profit Point    12%   Hold 0-30 minutes
Take-Profit Point    8%    Hold 30-60 minutes
Take-Profit Point    4%    Hold 60-120 minutes
Stop-Loss Point      -10%  Any time

4.2 Trailing Stop​

When profit exceeds 3.5%, a trailing stop automatically activates, locking in at least 4% profit.

4.3 Multi-Signal Exit​

V4 may combine multiple signals to determine exit timing, not relying solely on ROI and stop-loss.

V. Technical Indicator System​

5.1 Core Indicators​

Session IndicatorUTC TimeIdentify trading session
Trend IndicatorMACDTrend direction confirmation
Volatility IndicatorATRVolatility judgment
Momentum IndicatorRSIOverbought/oversold judgment

5.2 Multi-Dimensional Confirmation Principle​

# V4 Multi-Dimensional Confirmation
def v4_signal_confirm():
    signals = []
    if session_breakout:
        signals.append("breakout")
    if trend_continue:
        signals.append("trend")
    if volatility_break:
        signals.append("volatility")
    return len(signals) >= 2  # At least 2 signal confirmations

VI. Risk Management Highlights​

6.1 Dual Protection Mechanism​

V4 has 2 sets of protection parameters, providing more complete risk control:

Protection TypeParametersDescription
Session Filtersession_filterOnly trade during active sessions
Strength Filterstrength_thresholdNo trade when session strength is insufficient
Volume Filtervolume_thresholdNo trade when volume is insufficient

6.2 Stricter Signal Filtering​

V4 requires multiple signals to be confirmed simultaneously, reducing false signals.

VII. Strategy Strengths and Limitations​

✅ Strengths​

  1. More Signals: 3 sets of entry conditions, more opportunities
  2. Higher Take-Profit: 12% initial target, pursuing higher returns
  3. More Complete: Optimized through 4 iterations
  4. Multi-Dimensional Confirmation: Multi-signal verification, fewer false signals

⚠️ Limitations​

  1. More Complex: More parameters, higher learning curve
  2. Possible Over-Fitting: Multiple iterations may cause over-optimization
  3. Signal Conflicts: Multiple signals may produce contradictions
  4. Maintenance Cost: Requires more optimization work

VIII. Applicable Scenarios Recommendations​

IX. Applicable Market Environment Details​

LondiniumV4 is the ultimate version of the Londinium series. Code volume is approximately 250 lines, optimized through 4 iterations.

Its Money-Making Philosophy: More verification equals higher win rate

  • Multi-Signal Confirmation: 3 sets of conditions, at least 2 must be met
  • Higher Targets: 12% initial target, pursuing higher returns
  • Strict Filtering: Multi-protection mechanism

10.3 Backtesting vs Live Trading Differences​

Multiple-iteration strategies may over-optimize historical data, and live performance may not match backtesting.

10.4 Manual Trading Recommendations​

It is recommended to first understand the logic of V1 and V2 before using V4's multi-signal system.

XI. Summary​

LondiniumV4 is the ultimate version of the Londinium series. Its core value lies in:

  1. Multi-Signal Confirmation: 3 sets of entry conditions, improving signal quality
  2. Higher Targets: 12% initial target, pursuing higher returns
  3. Strict Filtering: Multi-protection mechanism, reducing false signals
  4. More Complete Optimization: 4 iterations of optimization, more mature logic

For quantitative traders, V4 is suitable for investors who pursue higher win rates and are willing to invest more time in optimization. It is recommended to start with V1 or V2 to get familiar, then upgrade to V4.
