Post From: Automatically Plot Lines For High/Low of First Bar of Session Only

pst - Pulled up this code from some other studies I have built and modified to meet this request.

There are no inputs to this study. If you set your session time correctly - it would pick the very first bar of the session and calculates the high/low for that chart ( chart can be of any type - not necessarily time based chart as long as session times are defined properly for the chart).

If you need any small customizations on this - can help you with that.
