That is the code I use to find Peak High and Low. Please help on the Peak Bar function. I am using the long way to find the different peak bars. What is the short way as the long takes up a lot of code. In the code above the first peak high is bar1 the next peak high after that is bar2 . My code is too long winded. Hope the long way is self evident and some kind soul can simplify. thanks
Please help with making the above an efficient code

Hi everyone, I want to find the latest swing high and swing low. I used this code to find it:
Using this I can find the swing high and swing low but it will search for the highest and lowest price on the whole array since I used the the WHOLE_ARRAY in the count parameter. What I want is to find only the latest swing high and changing the count parameter to number doesn't seems to work like what I want. Is there's a way that the EA would stop when It finds the latest swing high and swing low?
