Re: Scaling volume to fit on price chart

[dreamcircle60@xxxx]

Hi Tomasz,

Thank you very much for your prompt reply! Adding LastValue() did 
not seem to change anything. Since Highest() returns a number and 
LastValue accepts an array as the argument, I do not understand why 
you added LastValue() to the formula. (I noticed that you also wrote 
the formula that way in your Foreign example in the reference guide)

It appears to me that there is no way to detect the highest value 
within the visible pane (only the highest value back to the beginning 
of the data). If that is correct, then I don't think there is any 
way to scale the volume in the same manner as the Price Pane (which 
you already mentioned).

Thanks,
jim
