# Low

Get the low price for a bar on the chart symbol and timeframe.

## Signature

```typescript
Low(index: number): number
```

## Parameters

| Name    | Type     | Required | Description                                                                                                                   |
| ------- | -------- | -------- | ----------------------------------------------------------------------------------------------------------------------------- |
| `index` | `number` | Yes      | Valid reverse bar index: `0` = current bar, `1` = previous completed bar, higher = older; must satisfy `0 <= index < Bars()`. |

## Returns

The bar low price in symbol price units.

## Usage

* See [Bar indexing](/fto-indicators-docs/api-reference/current-symbol/bar-indexing.md): `0` = current/most recent bar; higher indexes = older bars.
* Bar `0` updates as new prices arrive during the active bar.
* Do not rely on invalid-index clamping. A negative index can expose a future bar when available or fail for missing data; other invalid indexes can also produce misleading results or throw.

{% hint style="info" %}
Bar `0` can still change while it is forming. Use index `1` for confirmed signals.
{% endhint %}

## Example

```typescript
const confirmedLow = this.api.Low(1)
const previousLow = this.api.Low(2)
const lowerLow = confirmedLow < previousLow
```
