Help to cqg formulas

Hi all I would like to write a cqg formula to see in a chart the difference between the daily movement of 2 contracts

What i really need is a chart like the NOB spread of CME, every day starts at 0 and just show the difference.

I did this formula, but it is not working

Last(RBEK4)-(RBEK4,D)-Last(HOEK4)-(HOEK4,D))

I tryed also with the
Pricetodollar(Last(RBEK4)-(RBEK4,D)-Last(HOEK4)-(HOEK4,D)))
still not working...

Any idea who to set this up???

Thanks

greg

 

No unfortunately is not the error

Thanks

 

The easiest on cqg as we were then explained :
-plot one chart
- plot chart * 2.0
- plot chart minus a number

for each chart in your formula

When this is checked :
- plot one chart minus another.

 

I am sorry, CQG is new form me and i do not understand what you mean with ploting the charts... and plot chart*2 ..
