Hover Info Restoration Fix - Complete

Problem Identified

The candle prediction hover info was missing, which previously showed:

Prediction accuracy percentage
Direction correctness (✓ or ✗)
Predicted vs Actual OHLCV values with percentage errors
Overall validation status

Root Cause Analysis

Backend: Accuracy data wasn't being calculated and stored for predictions
API: Live updates endpoint wasn't providing accuracy data with predictions
Frontend: Ghost candles weren't receiving accuracy data for tooltips

Fixes Applied

1. Backend Accuracy Calculation

Added _calculate_prediction_accuracy() method that computes:

{
    'accuracy': 87.5,  # Overall accuracy percentage
    'directionCorrect': True,  # Direction prediction correctness
    'avgPctError': 12.5,  # Average percentage error
    'actualCandle': [3320.1, 3325.4, 3318.2, 3322.8, 1250.5],  # Actual OHLCV
    'pctErrors': {  # Individual field errors
        'open': 0.8, 'high': 1.2, 'low': 0.5, 'close': 0.9, 'volume': 15.2
    }
}

2. Accuracy Data Storage

Added prediction_accuracy_cache to store accuracy data by prediction ID
Accuracy is calculated when predictions are validated
Cache is used to provide accuracy data for hover tooltips

3. Enhanced Live Updates API

Updated /api/live-updates to include accuracy data:

Calculates accuracy on-the-fly when predicted and actual candles match
Includes accuracy data in transformer predictions
Caches accuracy for future retrieval

4. Frontend Ghost Candle Enhancement

Ghost candles now store accuracy data when created
Added updateGhostCandleAccuracy() method to update existing ghost candles
Enhanced tooltip creation to show rich accuracy information

5. Validation Integration

Updated /api/train-validated-prediction to:

Calculate accuracy when predictions are validated
Store accuracy data in cache for hover display
Link accuracy to specific predictions by timestamp

Expected Hover Info Display

For Unvalidated Predictions:

PREDICTED CANDLE
O: 3320.15 H: 3325.42
L: 3318.23 C: 3322.61
Direction: UP

Status: AWAITING VALIDATION...

For Validated Predictions:

PREDICTED CANDLE
O: 3320.15 H: 3325.42
L: 3318.23 C: 3322.61
Direction: UP

--- VALIDATION ---
Accuracy: 87.5%
Direction: CORRECT ✓
Avg Error: 1.25%

ACTUAL vs PREDICTED:
Open: 3320.89 vs 3320.15 (0.8%)
High: 3326.12 vs 3325.42 (1.2%)
Low: 3318.45 vs 3318.23 (0.5%)
Close: 3323.18 vs 3322.61 (0.9%)
Volume: 1285.2 vs 1250.5 (15.2%)

Data Flow

Prediction Made: Model generates prediction with candle data
Ghost Candle Created: Added to chart with "AWAITING VALIDATION" status
Actual Candle Arrives: System compares predicted vs actual
Accuracy Calculated: Percentage errors and direction correctness computed
Tooltip Updated: Hover info shows detailed validation results

Verification Steps

Start inference: Make predictions and see ghost candles
Hover over ghost candles: Should show prediction details
Wait for validation: Tooltips should update with accuracy data
Check accuracy: Hover should show predicted vs actual comparison

The hover info system now provides complete visibility into prediction accuracy and validation results, helping you understand model performance at the individual prediction level!
