I am trying to use Worksheet or API. I’m looking for an indicator that will give me the highest high from the 3 minute chart and display it on the 30 second chart . The PDF Overlay Range Boxes almost does it but I’d like a line. Similar to the high of the day and low of the day line. Except it is from the current forming bar on the 3 minute chart that I will use like to have have it displayed on the 1 minute chart.
