indicator(title="Weekly Power 3", shorttitle="_WPower3", overlay=true, max_lines_count=100)

// Purpose:
//
// Did you know there is a simple line you can place on your chart to immediately make the weeks price action more understandable?
// Its called the Weekly Open Line. And its the opening price of the trading week.
// It was created by The Inner Circle Trader (ICT) and incorporates another one of his concepts called Power 3.

// Usage:
//
// Like all scripts publish by Infinity Trading, everything in the indicator is customizable by the user.
// Every label, line, or text can be individually toggled ON or OFF so the user has complete control over the element they want displayed on their chart.
// All of the lines can be individually adjusted by color, line style, or line width.
// The color and text color on the high and low of the week labels can be individually changed.
// And so much more!
