## New Intelligence Fields

| Field                   | Type    | Coverage                 | Value | Use Cases                               |
|-------------------------|---------|--------------------------|-------|-----------------------------------------|
| **followers_count**     | INTEGER | 100% future, 0% existing | ⭐⭐⭐⭐⭐ | Popularity tracking, sleeper detection  |
| **estimated_min_price** | REAL    | 100% future, 0% existing | ⭐⭐⭐⭐⭐ | Bargain detection, value gap analysis   |
| **estimated_max_price** | REAL    | 100% future, 0% existing | ⭐⭐⭐⭐⭐ | Overvaluation alerts, ROI calculation   |
| **lot_condition**       | TEXT    | ~85% future              | ⭐⭐⭐   | Quality filtering, condition scoring    |
| **appearance**          | TEXT    | ~85% future              | ⭐⭐⭐   | Visual assessment, restoration projects |

### Key Metrics Enabled
- Interest-to-bid conversion rate
- Auction house estimation accuracy
- Bargain/overvaluation detection
- Price prediction models

## Data Quality Fixes ✅
**Orphaned lots:** 16,807 → 13 (99.9% fixed)  
**Auction completeness:** 0% → 100% (lots_count, first_lot_closing_time)

## Dashboard Upgrades

### Priority 1: Opportunity Detection (High ROI)

**1.1 Bargain Hunter Dashboard**
```sql
-- Query: Find lots 20%+ below estimate
WHERE current_bid < estimated_min_price * 0.80 
  AND followers_count > 3
  AND closing_time > NOW()
```
**Alert logic:** `value_gap = estimated_min - current_bid`

**1.2 Sleeper Lots**
```sql
-- Query: High interest, no bids, <24h left
WHERE followers_count > 10 
  AND bid_count = 0 
  AND hours_remaining < 24
```

**1.3 Value Gap Heatmap**
- Great deals: <80% of estimate
- Fair price: 80-120% of estimate
- Overvalued: >120% of estimate

### Priority 2: Intelligence Analytics

**2.1 Enhanced Lot Card**
```
Bidding: €500 current | 12 followers | 8 bids | 2.4/hr
Valuation: €1,200-€1,800 est | €700 value gap | €700-€1,300 potential profit
Condition: Used - Good | Normal wear
Timing: 2h 15m left | First: Dec 6 09:15 | Last: Dec 8 12:10
```

**2.2 Auction House Accuracy**
```sql
-- Post-auction analysis
SELECT category, 
       AVG(ABS(final - midpoint)/midpoint * 100) as accuracy,
       AVG(final - midpoint) as bias
FROM lots WHERE final_price IS NOT NULL
GROUP BY category
```

**2.3 Interest Conversion Rate**
```sql
SELECT 
  COUNT(*) total,
  COUNT(CASE WHEN followers > 0 THEN 1) as with_followers,
  COUNT(CASE WHEN bids > 0 THEN 1) as with_bids,
  ROUND(with_bids / with_followers * 100, 2) as conversion_rate
FROM lots
```

### Priority 3: Real-Time Alerts

```python
BARGAIN:  current_bid < estimated_min * 0.80 
SLEEPER:  followers > 10 AND bid_count == 0 AND time < 12h
HEATING:  follower_growth > 5/hour AND bid_count < 3
OVERVALUED: current_bid > estimated_max * 1.2
```

### Priority 4: Advanced Analytics

**4.1 Price Prediction Model**
```python
features = [
    'followers_count',
    'estimated_min_price', 
    'estimated_max_price',
    'lot_condition',
    'bid_velocity',
    'category'
]
predicted_price = model.predict(features)
```

**4.2 Category Intelligence**
- Avg followers per category
- Bid rate vs follower rate
- Bargain rate by category

---

## Database Queries

### Get Bargains
```sql
SELECT lot_id, title, current_bid, estimated_min_price,
       (estimated_min_price - current_bid)/estimated_min_price*100 as bargain_score
FROM lots
WHERE current_bid < estimated_min_price * 0.80
  AND LOT>$10,000 in identified opportunities
```
