You cannot use a variable in its declaration. You need to declare it first.

Here is how you can fix that issue. You have

graphgo = 0.0
graphback = 0.0
graphgo := close[1]>graphgo[1]? max(go,graphgo[1]) : go
graphback := close[1]<graphback[1]? min(back,graphback[1]) : back

Also, you need to use the color namespace for the colors.

So, change lines like this:

lineset = jump == 1 ? lime : red

To this:

lineset = jump == 1 ? color.lime : color.red
