I want to have $advn and $decn on same chart both starting from 100 but cannot figure out how to do it. I tried to capure the 1st (1min) data point so that I can index the data so that $advn(indexed) = $advn / $advn (1st minute) * 100 and $decn(indexed) = $decn / $decn(1st minute) * 100, but I was not able to capture the 1st minute $advn and $decn. thanks in advance.
