Parameters let you customize your signals without changing the code. You can set the parameter values for your signal when configuring it for your bot. This allows you to fine-tune your signal to your liking without having to write/change any code.

## SDK Parameter Types

You can register the parameters in the registerParams() function of your signal.

```php theme={null}
$myString = $this->registerStringParam("myString", "Hi", "My String", "This is my description", "My Category");

$myBool = $this->registerBoolParam("myBool", true, "My Bool");

$myBoolSwitch = $this->registerBoolParam("myBoolSwitch", false, "My Bool Switch");
$myBoolSwitch->inputType = ParamInputType::Switch;

$myInt = $this->registerIntParam("myInt", 1, 0, 10, "My Int");

$myIntSlider = $this->registerIntParam("myIntSlider", 5, 1, 20, "My Int Slider");
$myIntSlider->inputType = ParamInputType::Slider;

$myFloat = $this->registerFloatParam("myFloat", 1.123, null, null, "My Float");
$myFloat->step = 0.001;

$myFloatSlider = $this->registerFloatParam("myFloatSlider", 1.5, 1, 2, "My Float Slider");
$myFloatSlider->inputType = ParamInputType::Slider;
$myFloatSlider->step = 0.1;

$myEnum = $this->registerEnumParam("myEnum", MyEnum::class, MyEnum::LowRisk, "My Enum", null, "My Category");
```

## Using Parameters

You can access the parameter values in your signal using the getParam() function.

```php theme={null}
$myIntValue = $this->getParam("myInt");
```

## Setting parameter values

Parameter values can be set in the bot configuration. The values set in the bot configuration will override the default values set in the registerParams() function.

<Tip>
  The parameter values set in the bot configuration are specific to each bot. This means you can have multiple bots of the same type running with different parameter values.
