• OB zones should align with actual supply/demand areas
• Strength calculation should reflect actual price reaction
• Fresh OBs should be prioritized over stale ones
• OB boundaries should be clearly defined

Expected Results:

EURUSD: 15-25 valid OBs per day
GBPUSD: 20-30 valid OBs per day
XAUUSD: 10-20 valid OBs per day
Lower volatility pairs: 8-15 valid OBs per day

Scenario 2: Fair Value Gap Detection

Test Parameters:

Minimum Gap Size: 5 pips
Maximum Gap Age: 24 hours
Gap Fill Threshold: 50%
Test Duration: 1 week of data

Validation Criteria:

• Gaps should represent actual price inefficiencies
• Gap boundaries should be accurate (high of lower candle to low of higher candle)
• Gap classification (bullish/bearish) should be correct
• Gap mitigation tracking should be accurate

Expected Results:

EURUSD: 5-10 valid FVGs per day
GBPUSD: 8-15 valid FVGs per day
XAUUSD: 10-20 valid FVGs per day
Quiet sessions: 2-5 valid FVGs per day

Scenario 3: Break of Structure Detection

Test Parameters:

Swing Point Lookback: 20 bars
Confirmation Bars: 3
Minimum Break Distance: 10 pips
Test Duration: 1 week of data

Validation Criteria:

• BOS should represent actual trend changes
• Swing high/low identification should be accurate
• Break confirmation should be reliable
• Direction classification should be correct

Expected Results:

EURUSD: 3-8 valid BOS per day
GBPUSD: 5-12 valid BOS per day
XAUUSD: 4-10 valid BOS per day
Trending markets: Higher BOS frequency

Scenario 4: Liquidity Sweep Detection

Test Parameters:

Equal High/Low Tolerance: 3 pips
Sweep Distance Threshold: 10 pips
Lookback Period: 100 bars
Test Duration: 1 week of data

Validation Criteria:

• Sweeps should target actual equal highs/lows
• Sweep distance should be meaningful
• Sweep direction should be correctly identified
• False sweep filtering should be effective

Expected Results:

EURUSD: 2-6 valid sweeps per day
GBPUSD: 4-8 valid sweeps per day
XAUUSD: 3-7 valid sweeps per day
Range-bound markets: Higher sweep frequency

🧪 Pattern Combination Testing

Test 1: Complete Strategy Sequence

Sequence: Liquidity Sweep → BOS → FVG → Order Block

Test Methodology:

1. Run EA on each symbol for 1 week
2. Log all pattern detections with timestamps
3. Manually verify 20% of detected sequences
4. Calculate accuracy percentage

Success Criteria:

• Pattern sequence logic should be sound
• Timing relationships should be correct
• False positive rate should be <20%
• Complete sequences should occur 1-3 times per day per symbol

Test 2: Multi-Timeframe Alignment

Test Parameters:

M1: Entry signal patterns
M15: Pattern confirmation
H4: Bias alignment
D1: Trend confirmation

Validation Process:

1. Compare M1 signals with higher timeframe bias
2. Verify alignment accuracy
3. Test bias override functionality
4. Validate neutral bias handling

Expected Alignment Rates:

M1 with M15: 70-80% alignment
M1 with H4: 60-70% alignment
M1 with D1: 50-60% alignment

📋 Validation Test Execution

Phase 1: Individual Pattern Testing (Day 1-2)

For each symbol in test matrix:
1. Enable debug mode for detailed logging
2. Run Strategy Tester for 1 week of data
3. Extract pattern detection logs
4. Perform manual verification on sample set
5. Calculate accuracy metrics
6. Document any anomalies or issues

Phase 2: Pattern Combination Testing (Day 3-4)

For each symbol:
1. Run complete strategy sequence detection
2. Log all pattern combinations
3. Verify sequence timing and logic
4. Test multi-timeframe alignment
5. Validate trade signal generation
6. Check for false positives/negatives

Phase 3: Cross-Symbol Analysis (Day 5)

1. Compare pattern detection rates across symbols
2. Analyze performance in different market conditions
3. Identify symbol-specific adjustments needed
4. Validate parameter consistency
5. Document optimization recommendations

🔧 Troubleshooting Common Issues

Low Pattern Detection Accuracy

• Review parameter sensitivity
• Check symbol-specific characteristics
• Validate historical data quality
• Adjust detection thresholds

High False Positive Rate

• Tighten pattern validation criteria
• Increase confirmation requirements
• Add additional filtering conditions
• Review pattern definition logic

Inconsistent Cross-Symbol Performance

• Implement symbol-specific parameters
• Add volatility-based adjustments
• Consider spread and liquidity factors
• Validate pip value calculations
