Math on indicator bars only

[MFitz73]

Hi guys, I am trying my best but can't figure which way to go. I have a chart indicator that paints an arrow below the criteria met candle or candles. What I am trying to do is add up a value(say close price, if more than one I would want the average of the close prices) for each candle bar and paint a horizontal line on the chart.
What I can do is I can script the indicator. but I can not figure how to go about collecting the data and draw the line.
would I use the fold script here? I'm currently trying to write simple fold scripts to get a handle on it but... well here I am. lol
any help would be greatly appreciated.
thanks
Mike

@Svanoy I just ran the code in on demand and its painting the line far away from the price action. for example the 3 candles that are being calculate have values of (for example) 21.33, 21.37, 21.41 and the line is painted at 44 on the chart. I am running the code on a 2min chart.

@MFitz73
There was an issue if the amount of bars on a chart being less than the value of the offset causing the last bar number value to not be retrieved.
I have developed a work around for that and have been updating scripts I've posted here as I find them.
I've updated the code in post #7 with this work around and should now work no matter the amount of bars displayed on the chart.
If you find any other problems with the script, please let me know.

Ok been running the updated code in OnDemand and looks like its processing all the math correctly and painting
the threshold line in the right spot now. I will run it this week realtime. will report back. So far everything look
neat and reliable! Thank you @Svanoy !
