last swing high or swing low

[[Deleted]]

hello, does anyone know of an indicator or mt4 code that can determine the last swing high or low? Something like, for a swing high, finding a "high bar" that has two or more bars on either side below it.

Thanks Brad

You mean like fractals ?

yes, it looks like fractals is what I want.

Thanks for the tip!

Any suggestions on where I could see some examples of how they are used?

or roll your own (from my code).
