Hello
here is a screenshot about what i want to do : plot points at the extremes of high / low

An Upswing starts when a bar s high and low prices rise above the respective high and low prices of the latest Downswing. Prices then remain in an Upswing until such a bar that the high and low prices decline below the respective high and low prices of the highest bar of the Upswing. The highest price in the Upswing is called a TOP

A Downswing starts when a bar s high and low prices decline below the respective high and low prices of the highest bar of the latest Upswing. Prices then remain in a Downswing until a bar high and low prices rise above the respective high and low prices of the lowest bar of the Downswing. The lowest price in the Downswing is called a BOTTOM.

in my code, points aren't plotted at the extremes of high / low

THANKS YOU FOR HELP
