Develop MQL5 indicator

 
Hello, I'm looking for a way to develop an indicator that will draw a high at the highest value of a given range. I tried several possibilities and looked in the CodeBase, but nothing helped. Thanks in advance!
 
If no one helps on this thread (for free) so you may consider to go to Freelance.
 
Maybe you should ask the German forum to get more help. I'm sure there's something like this in the code base.
