Subject: [amibroker] Strange indicator plot
scaling
>
Grateful if someone could help me see where the code below is going
funny.
> Everything plots fine until you scroll left (or zoom out) to the
extreme
> left-hand, i.e. the first bar. When I do this the indicator
scaling goes
> AWOL and I just end up with a straight line due to the
plot creating
> huge numbers. Can't see why for the life of me...and I
don't see the
> problem with indicators that are constructed in a similar
way.
> Can anyone replicate my problem? Or better still, fix it!
>
TIA
