New day arrow

[jabowen]

I am trying to place an arrow on the chart at the start of each day. However the code is only placing an arrow for the start of the last day.

Another way without using an indicator and with grid off to see the beginning of new day is

properties ==> common ==> select "Show Period Separators"

This way the beginning of the new day is on the chart indicated with a vertical dotted line

Control Y = Show Period Separators
