# Fields API Reference

Field enums provide type-safe access to screener data.

## Field Classes

| Class | Screener | Field Count |
|-------|----------|-------------|
| `StockField` | `StockScreener` | ~3,526 |
| `CryptoField` | `CryptoScreener` | ~3,108 |

| `BondField` | `BondScreener` | ~201 |
| `FuturesField` | `FuturesScreener` | ~393 |
| `CoinField` | `CoinScreener` | ~3,026 |

## Import

```python
from tvscreener import StockField
from tvscreener.field import StockField, CryptoField, ForexField
```

## Comparison Operators

Fields support Python comparison operators for filtering:

### Numeric Comparisons

```python
StockField.PRICE > 100          # Greater than
StockField.PRICE >= 100         # Greater than or equal
StockField.PRICE < 100          # Less than
StockField.PRICE <= 100         # Less than or equal
StockField.PRICE == 100         # Equal to
StockField.PRICE != 100         # Not equal to
```

### Range Methods

```python
StockField.PRICE.between(50, 200)       # Value in range [50, 200]
StockField.PRICE.not_between(50, 200)   # Value outside range
```

### List Methods

```python
StockField.SECTOR.isin(['Technology', 'Healthcare'])
StockField.SECTOR.not_in(['Finance', 'Utilities'])
```

## Field Properties

Each field has accessible properties:

```python
field = StockField.PRICE

field.name          # Enum name: 'PRICE'
field.value         # Field definition tuple
field.label         # Human-readable label
field.field_name    # API field name
field.format        # Data format type
```

| `number_group` | Large numbers | VOLUME, SHARES |
| `text` | Text string | NAME, SECTOR |
| `bool` | True/False | IS_PRIMARY |
| `date` | Date | EX_DIVIDEND_DATE |

## Time Intervals

Technical fields support multiple timeframes:

```python
# Default (daily)
StockField.RELATIVE_STRENGTH_INDEX_14

# With specific interval
StockField.RELATIVE_STRENGTH_INDEX_14.with_interval('60')   # 1 hour
StockField.RELATIVE_STRENGTH_INDEX_14.with_interval('240')  # 4 hours
StockField.RELATIVE_STRENGTH_INDEX_14.with_interval('1W')   # Weekly
```

### Available Intervals

| Code | Timeframe |

StockField.RELATIVE_STRENGTH_INDEX_14.with_history(1)

# RSI from 5 days ago
StockField.RELATIVE_STRENGTH_INDEX_14.with_history(5)
```

## Field Discovery

### Search

Find fields by name:

```python
matches = StockField.search("dividend")
for field in matches[:10]:
    print(f"{field.name}: {field.label}")
```

### Presets
