## Basic Usage

```bash
longbridge calc-index TSLA.US
```

```
| Symbol  | PE TTM | PB    | DPS Rate | Turnover Rate | Total Market Value  |
|---------|--------|-------|----------|---------------|---------------------|
| TSLA.US | 341.83 | 15.79 | -        | 2.21          | 1296915542310.08    |
```

## Examples

### Check P/E and P/B ratios

```bash
longbridge calc-index TSLA.US NVDA.US --fields pe,pb
longbridge calc-index TSLA.US NVDA.US --fields pe,pb --format json
```

Calculates the specified indexes for each symbol. Multiple symbols and multiple indexes can be requested in a single call. Only indexes that have data appear in the JSON output — indexes with no value are omitted.

### Default indexes (PE, PB, dividend yield, turnover rate, market cap)

```bash
longbridge calc-index TSLA.US
```

When `--fields` is omitted, the default set is returned: `pe`, `pb`, `dps_rate`, `turnover_rate`, `mktcap`.

### Options greeks for a derivative

```bash
longbridge calc-index 24760.HK --fields delta,gamma,vega,theta
```

For options and warrants, request greeks directly. Only indexes applicable to the instrument type will appear in the output. Greek values are only meaningful for option/warrant symbols — passing a plain stock symbol returns no greek data.
