# Swing High and Swing Low
# tomsk
# 11.18.2019
# As requested by chillc15 I have modified [USER=1174]@RobertPayne[/USER] 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

this is the code for the colored candles. I have turned off the swing high and low areas and just kept the colored candles.
I also use this as a further confirmation. I just use the arrows and have turned off the colors.

OK, let's formalize at least one pattern signal:
Can it be coded referencing ZigZag parameters? Like breaching a previous ZZ High creates a signal?
Ben, Is there any indicator that we can use similar to use to avoid false signals?
I can help you
I may have suggested this,... it's your start to the simplest way of trading,.. listen to the entire presentation, it was my lightbulb that had me in tears as I understood after years, how simple it can be...
Yes, I would suggest B&W chart,..it took me 3 days to never want to use black background. Your eye picks up pattern easier. One chart with VolStop and the other,...trend only,...but trend is the easiest,.....buy at support, sell at resistance or break of trend, this was a buy early on and sell at consolidation, it never broke trend and is now trending,...moving toward trend....
