Thanks Wilf- yes comparing to TG would be good- if you can find a chart that has both ND and NS signals on it then any daily chart showing about a 6 month period would do so the relative volume is fairly easy to read and compare. I've tried to include headings etc within the code to make it easier to identify which bits are what and the language is similar enough that hopefully the formulas and built in functions like "tr" and "atr" are easily identified. Let me know if you need some explanation!
