My fault. I had the chart showing 'Weekly' data. Return to
daily data makes the Gap line make sense.

<FONT face=Verdana color=#800000

to correct using Symbol/Quote Editor or maybe with the new database
purify tool.

Re: [amibroker] Graph plots using loops
Great plot! One problem I have is that on many charts I
show a green 'nobbly' line at zero (see attached). This compresses the rest
of the chart. Is there a way to avoid this? I couldn't see anything obvious
in the code.
Thanks,
Steve
