Quick-tip 67 | Change alpha value of a color in TradeStation EasyLanguage

QuickTip67 is a TradeStation EasyLanguage indicator that demonstrates how to change the alpha value of a color input as a string. The EasyLanguage indicator draws a rectangle when it is first applied to the chart. It colors the fill (using the string input: Col). The alpha value is changed based on the integer input: Alpha. The color of the rectangle itself (the outline) is colored based on the same color input (using the string input: Col) except it is fully opaque.
