Out of the last x bars mark bars with the same high/low

I was unable to find an existing indicator for the above.

Look back period = x

examples below are based on a look back period of 10

mark the high of the bars that had the same high in the last 10 bars

mark the low of the bars that had the same high in the last 10 bars


ideally

if 4 of the highs during the look back period had the same high then mark each of those bars with the number 4.

if 4 of the lows during the look back period had the same low then mark each of those bars with the number 4

if 3 of the highs during the look back period had the same high then mark each of those bars with the number 3

and so on.

or even mark the most recent bar that had an equal high if that is so much easier

minimum number with same h/l would of course be 2.

So far I have been able to either find everything I needed or written the code myself. In some cases I have made my own versions of complex stuff and worked out what to change.

I am open to custom development also.

Just thought it would be a pretty easy thing to code for an experienced NT dev.

Especially if it was just to mark the bar highs and lows with a dot e.g. not do the numbering.

Open to any ideas.

This would be an extremely good tool to have.
