I would like to code a positive/negative divergence. I mean between an indicator and price of any security. I tried but i have faced a lot of problem. How could i code a series of highter low or a second low tha is higher that the previous low ( viceversa in negative divergence) of Macd  for eaxmple and link this 2 or more than 2 higher low with  lower lows of the security. 

Thank for any help 

Strenght is how many bar swing, and lenght is how far back you can look for that swing.  a 10 bars swing is 5 bars up and 5 bars down.

SwingHighBar, returns how many bars ago the swing high occured. The last argument is the occurence number, 1, last , 2 2 occurences ago ect.
