.SYNOPSIS
   Calculate Fibonacci retracement levels based on the provided StartPrice and EndPrice.

.DESCRIPTION
   This function calculates Fibonacci retracement levels for a given price range.

.PARAMETER StartPrice
   The starting price for the Fibonacci retracement calculation.

.PARAMETER EndPrice
   The ending price for the Fibonacci retracement calculation.

.EXAMPLE
   The following example demonstrates how to use the function:
   Get-FibonacciRetracement -StartPrice 100 -EndPrice 200
#>

function Get-FibonacciRetracement {
    [CmdletBinding()]
    param(
        [Parameter(Mandatory = $true)]
        [double]$StartPrice,
        [Parameter(Mandatory = $true)]
        [double]$EndPrice
    )

    # Fibonacci retracement levels calculation
    $retracementLevels = @()
    $retracementLevels += ($EndPrice - ($EndPrice - $StartPrice) * 0.236)  # 23.6% retracement level
    $retracementLevels += ($EndPrice - ($EndPrice - $StartPrice) * 0.382)  # 38.2% retracement level
    $retracementLevels += ($EndPrice - ($EndPrice - $StartPrice) * 0.5)    # 50% retracement level
    $retracementLevels += ($EndPrice - ($EndPrice - $StartPrice) * 0.618)  # 61.8% retracement level
    $retracementLevels += ($EndPrice - ($EndPrice - $StartPrice) * 0.786)  # 78.6% retracement level

    return $retracementLevels
}
