# longbridge margin-ratio

Look up the margin requirements for a symbol — initial, maintenance, and forced liquidation ratios.

## Basic Usage

```bash
longbridge margin-ratio TSLA.US
```

```
| Field                    | Value   |
|--------------------------|---------|
| Symbol                   | TSLA.US |
| Initial Margin Ratio     | 0.35    |
| Maintenance Margin Ratio | 0.33    |
| Forced Liquidation Ratio | 0.25    |
```

## Examples

### Check margin requirements before buying on margin

```bash
longbridge margin-ratio TSLA.US
# Output as JSON for scripting
longbridge margin-ratio TSLA.US --format json
```

Displays the initial margin ratio, maintenance margin ratio, and forced liquidation ratio for the symbol. Use this before placing a margin buy to understand the capital requirements.

### Compare multiple symbols

```bash
longbridge margin-ratio TSLA.US NVDA.US
```

Pass multiple symbols to compare their margin requirements side by side.

## Requirements

OAuth trade or account permission is required to query margin ratios. See [Trade Permissions](/docs/trade/) for setup details.
