Won't `na(indicatorValues) or indicatorValues.rows()==0` (line 33) produce an error if indicatorValues is na? As far as I know, both arguments of logical operators are evaluated in Pine Script.

@moebius1977, good catch. Yes, it does. May need to change it to nested ternary statement instead.
@moebius1977, hmm. Don't think so. I can check. But, I use na ternary on loops all the time. Never faced issue
Trendoscope
⋅
@HeWhoMustNotBeNamed, hmm. Actually you are right. I assumed that indicator of lows will always be lower than that of indicator of highs. Apparently not.
moebius1977
⋅
@HeWhoMustNotBeNamed, also, based on line 35, Indicator.indicatorHigh looks like "highest of the indicator values" rather than "Indicator Value applied on High" as stated in the @Field description.
Trendoscope
⋅
@moebius1977, not really. It's indicator value applied on high and indicator low is indicator value applied on low. But, they need to be passed as such by caller.

Absolutely beautiful! I am just starting with PineScript and my first move was to go your way, typify and objectify everything. But then I found that UDT of arrays may be faster than array of UDT's, so went that way for now. Here is how I tested it. Not sure my test method is 100% accurate, but looks like it is about 20-30% more efficient for large arrays to store values in individual arrays rather than make an array of UDT objects tradingview.com/script/F4dFQBtz-Profiling-array-of-UDTs-vs-UDT-of-arrays/

@moebius1977, I have noticed slight lag as well. But, using array of UDTs is more easy to read and maintain. Hopefully pine team will work on improvements.

Your code looks impressive! I'm quite new to Pine Script. Could you give some hint how to plot just one zigzag (I mean one level)?
