Custom High/Low Indicator with Labels

I have a really good mental image of what I would like to do, but stuck. Here is what I am looking for, in a nutshell:

• Inputs for Length and Aggregation Period, so I could select ’10 Days’ or ’30 Minutes’ or whatever
• Study would then:
  • Calculate the HighestHigh over the above timeframe, using my inputs
  • Look intraday for a new high that is greater than the Highest High
  • If true, paint a bubble at the candle where the new high occurred
• Create a label to look something like this:
  • { New [Len_Agg] High: $12.34 }
  • If a new high had not been made, label would say ‘New High: No’

I’d then do the exact same thing for ‘Low’, using a second label.

Would also love to be able to then scan that criteria, i.e. – Where ‘New High’ is true or something…? Essentially, tell me the stocks that have made a new high in the last 10 days or a new low in the last 30 weeks or whatever timeframe. But maybe that is separate?

I have been at this for a while and am stuck. PLEASE HELP OH GREAT ONE!
