Simple script which marks out key swing highs & lows.
One of the only indicators I have on the chart most days - perfect for naked charting - quickly helps you to visually identify key areas of interest
An extension of Bill Williams fractals - aka short term swing points
Allows you to filter for only the most prominent swing points - you can even overlay multiple swingpoint filters in different colours (as per example chart)
The number ( Fractal Periods) is simply: - the number of less prominent points either side of your swing high/low - example shown on the chart
Otherwise make a fist - look at your 5 knuckles - swing high is your middle knuckle - 2 lower points either side
Bill Williams Original Fractal: Fractal Periods = 2
Your Fractal Period for Filtering: 3, 4, 5, 30, 365, etc
Allows you to find swing points down to: Fractal Periods = 1
