@chillc15 Per your request, I have modified
@RobertPayne code to include SwingHigh points which are now plotted in CYAN with the swing high points painted in PINK. So now you have both swing high and low on your charts.
Code:

WOW! Thanks tomsk very much appreciated.
If you don’t mind I have a few questions that will help me learn and maybe others.
Obviously this swing-high-swing- low is similar to the Trend Reversal indicator as discussed on here and also the Zig-Zag.
As I watched Roberts swing-low this is a repainter as it waits to determine its bottom. With the addition of the swing-high I assume it will repaint as well until the top is determined as well.
The burning question is what condition in the code eventually keeps the bar locked in either high or low and it will no longer repaint.
Is it a certain amount of bars looking back?
For a swing-high does there have to be a certain amount of down bars before it locks itself in? Vice-versa at the low.
I know there are some zig-zag indicators using an ATR reversal factor and other conditions. Is it possible to implement this swing-high-swing-low into a zig-zag as well?
If you are open I can send you a zig-zag I have been working with to see if they could be implemented together.
Thanks again
For those that may be visual like me you can adjust the colors of the candles if you like. Here is another version.
# ADJUST CANDLE COLORS
# change candle colors just to make it easier to see what we are working with
AssignPriceColor(if swingLow then Color.YELLOW else if swingHigh then Color.BLUE else Color.CURRENT);
