## Syntax

`MIN(int period)`

`MIN(ISeries\<double\> input, int period)`

**Returns default value**

`MIN(int period)[int barsAgo]`

`MIN(ISeries\<double\> input, int period)[int barsAgo]`

## Return Value

**double;** Accessing this method via an index value **`[int barsAgo]`** returns the indicator value of the referenced bar.

## Parameters

| Parameter | Description                                                                                     |
| --------- | ----------------------------------------------------------------------------------------------- |
| input     | Indicator source data ([Series\<T>](/developer/desktop-sdk/references/common/iseriest/seriest)) |
| period    | Number of bars used in the calculation                                                          |

## Examples

```csharp
// Prints the lowest low value over the last 20 periods
double value = MIN(Low, 20)[0];
Print("The current MIN value is " + value.ToString());

// Note the above call with a barsAgo of 0 includes the current MIN of the input low series in the value. If we want to check for example for a break of this value, storing the last bar's MIN would be needed.
double value = MIN(Low, 20)[1];
       
if (Low[0] < value)
  Draw.ArrowDown(this, CurrentBar.ToString(), true, 0, High[0] + TickSize, Brushes.Red);
```
