# SetFixedMinMaxValues

Sets fixed minimum and maximum values for the indicator's scale.

## Syntax

```typescript
SetFixedMinMaxValues(aMin: number, aMax: number): void
```

## Parameters

* `aMin` - A number representing the minimum value for the indicator's scale.
* `aMax` - A number representing the maximum value for the indicator's scale.

## Return Value

This method does not return a value.

## Description

The `SetFixedMinMaxValues` method sets fixed minimum and maximum values for the indicator's scale. This is particularly useful for oscillators and other indicators that should be displayed within a specific range.

## Example

```typescript
// Set fixed scale for RSI (0-100)
this.api.SetFixedMinMaxValues(0, 100)

// Set fixed scale for Stochastic (0-100)
this.api.SetFixedMinMaxValues(0, 100)

// Set custom range for an oscillator (-50 to 50)
this.api.SetFixedMinMaxValues(-50, 50)
```
