[Alec Hilton Silva Couto]

Greetings community

I would like to ask how can I get the last zigzag high and low and display on the screen using the comment().

Anyone can help please??

Best Regards

1. Loop starting at the latest until you read a non-zero/non-EMPTY_VALUE value.
2. Continue until you read the next value.
3. Now you have a high and a low.

Thank you for your reply William. It is possible to give a link to a example or code?

CopyBuffer(ZigZagHandle,0,0,20,ZigZagBuffer);
      for(int x=0;x<20;x++)
        {
         if(ZigZagBuffer[x] != EMPTY_VALUE && ZigZagBuffer[x] != 0.0)
           {
            if(n<10)
              {
               p0 = NormalizeDouble(ZigZagBuffer[1],5);
              }
           }
        }  

So far I have reach this point I would like to get the last 3 non-zero values from the zigzag indicator buffer. Can Someone help me with it.

              }
           }
        }  

What is the variable n?  

What is the variable p0 and why, no matter what the loop does it is given the value of the 2nd element of ZigZagBuffer?
