✅ Test Breakdown

1. Manual Calculation Validation (3/3 ✅)

Purpose: Verify barrier label calculations match hand-computed expected values

1. ✅ test_manual_calculation_buy_label

   • Validates: Buy signal detection when price hits upper barrier
   • Scenario: Strong uptrend scenario, profit target reached
   • Expected: Label = 1 (Buy)
   • Result: ✅ PASSED

2. ✅ test_manual_calculation_sell_label

   • Validates: Sell signal detection when price hits lower barrier
   • Scenario: Strong downtrend scenario, stop loss triggered
   • Expected: Label = -1 (Sell)
   • Result: ✅ PASSED

3. ✅ test_manual_calculation_hold_label_time_expiry

   • Validates: Hold label when time horizon expires without barrier touch
   • Scenario: Sideways movement, no barrier breached
   • Expected: Label = 0 (Hold)
   • Result: ✅ PASSED

2. Distribution Tests (4/4 ✅)

Purpose: Verify label distributions match theoretical expectations

4. ✅ test_label_distribution_within_expected_range

   • Validates: Overall label distribution is within reasonable bounds
   • Expected: Mix of buy/sell/hold labels, no single class > 60%
   • Result: ✅ PASSED

5. ✅ test_symmetric_barriers_balanced_distribution

   • Validates: Symmetric barriers produce balanced buy/sell ratio
   • Expected: Buy count ≈ Sell count (within 20% tolerance)
   • Result: ✅ PASSED

6. ✅ test_asymmetric_barriers_higher_profit_target

   • Validates: Asymmetric barriers (2x profit vs 1x stop) affect distribution
   • Expected: More buy labels than sell labels (profit target harder to hit)
   • Result: ✅ PASSED

7. ✅ test_label_accuracy_against_manual_calculation

   • Validates: Automated labeling matches manual calculation for specific bars
   • Expected: Exact label matches for known scenarios
   • Result: ✅ PASSED

3. Market Scenario Tests (3/3 ✅)

Purpose: Verify labeling adapts correctly to different market regimes

8. ✅ test_strong_uptrend_produces_majority_buy_labels

   • Validates: Strong uptrend (prices consistently rising) produces buy labels
   • Expected: > 60% buy labels
   • Result: ✅ PASSED

9. ✅ test_strong_downtrend_produces_majority_sell_labels

   • Validates: Strong downtrend (prices consistently falling) produces sell labels
   • Expected: > 60% sell labels
   • Result: ✅ PASSED

10. ✅ test_volatility_scaling_adapts_barrier_width

    • Validates: Barrier width scales with market volatility
    • Scenario: High volatility period has wider barriers than low volatility
    • Result: ✅ PASSED

4. Edge Case Tests (3/3 ✅)

Purpose: Verify system handles edge cases and boundary conditions

11. ✅ test_gap_scenario_labels_still_valid

    • Validates: Large price gaps don't break labeling logic
    • Scenario: 10% overnight gap, followed by normal trading
    • Result: ✅ PASSED

12. ✅ test_time_horizon_prevents_stale_labels

    • Validates: Time horizon enforcement prevents stale labels
    • Expected: No labels assigned beyond max_time_horizon
    • Result: ✅ PASSED

13. ✅ test_average_time_to_label

    • Validates: Average time to barrier touch is within reasonable range
    • Expected: < max_time_horizon (e.g., < 5 bars)
    • Result: ✅ PASSED

✅ Validation Summary

Triple-Barrier Method Correctness ✅

1. Buy Label Logic: ✅ Correctly identifies profitable opportunities (upper barrier)
2. Sell Label Logic: ✅ Correctly identifies stop-loss scenarios (lower barrier)
3. Hold Label Logic: ✅ Correctly assigns hold when time horizon expires
4. Barrier Width Scaling: ✅ Adapts to market volatility
5. Time Horizon Enforcement: ✅ Prevents stale labels
6. Gap Handling: ✅ Handles large price gaps gracefully

Label Distribution Validation ✅

1. Symmetric Barriers: ✅ Balanced buy/sell ratio
2. Asymmetric Barriers: ✅ Profit target bias (more buys than sells)
3. Market Regime Adaptation: ✅ Uptrends → buy labels, downtrends → sell labels
4. Reasonable Distribution: ✅ No single class dominates (< 60%)

Manual Calculation Validation ✅

1. Buy Signal: ✅ Matches hand-computed expected label (1)
2. Sell Signal: ✅ Matches hand-computed expected label (-1)
3. Hold Signal: ✅ Matches hand-computed expected label (0)
