Hey C- Welcome to the forum! Since you are creating the files anyway, why not just create a day session file and a night session file. Open both charts and then drag the price plot from one of the charts to the other. With two sets of data, you could write whatever composite indicator you desired.

hey c.... g just threw the composite last sentence in for extra info...... his first and second sentences were the answer..... as g mentioned, just place the 2 data files in seperate folders.... say something like [color=blue:9bda83b146]C:\\MetaStock Data\\day session\\intc[/color] and [color=blue:9bda83b146]C:\\MetaStock Data\\night session\\intc[/color] ..... there are other methods but that is the best known to me..... now open both your intc day session and night session charts.... right click on the night session price bars and choose copy..... paste that onto the day session..... now both will be on the same chart.... you will need to change the weight and color of one otherwise they will blend together.... i usually have one set at weight size 2 or 3 and the colors very light green and very light red..... the overlayed chart will be set to normal weight and dark red/green colors..... once its set as you like , save as template or layout..... then its a done deal......holler back if ya don't follow......h
