Hello Osgem, I am glad the 'Padding' helped with your chart display. I attach an AFL file that will Plot the price array for the composite
index. I have added volume into the code as you requested and also the choice
to plot either gross composite values or average symbol values using a counter
slotted into the price array field "I". For the fun of it, I have
glossed-up the background color and given you the ability to vertically scale
the volume - courtesy of Amibroker's functionality and the code sharing of the
Amibroker community. You will need to run a scan of this AFL file each time you use it and
then plot the artificial symbol "~MyIndex" from the Formula Editor
window. This code should be enough for you to fly solo from hereon in. I repeat the code below in case you don't receive emails from this
Group. Watch out for word wrap if you copy and paste. Good luck, Regards, Gordon

Also if I wish to include volume of all the scrips in the composite what addition is needed ? Please help. Thanks Osgem Please note that this group is for discussion between users only.
