Hi Paul,
Thank you for your answer.
This seems an enormously complex solution for what must be a very common
problem. Previously, I used Wealth-lab Developer and it had a process that
(fundamentally) allowed the subject symbol to be aligned with the foreign
symbol (rather than the reverse in AmiBroker).
Does anyone else have a suggestion?
Regards
Robert.

if you want to veiw chart that way, you need to
create artifical symbols using addtocomposite with the pad and align checked
and using foreign function.

Subject: [amibroker] Handling Missing Bars in a complex Chart layout
Hi All,
I have a multi-pane Chart layout that I use both from the AA results window
and from the drop-down box at the top of the chart screen.
Some of the securities I trade have missing bars. In the AA I can set ?Pad
and Align? and this handles missing bars perfectly. When I come to display
the results of a Chart (with missing bars) the display does not correspond
with back-tester results, due to the missing bars.
I have been working with the Foreign and SetForeign commands in chart
presentation. This enables me to show the missing bars, provided I set a
reference symbol (say the Index that trades every day) as the ?Subject?
symbol and make the symbol I want to display the ?Foreign? symbol. This
works for a ?one-off? test but I have not yet found a way to use it
?cleanly? in my system.
Can any-one suggest an AFL coding approach that:
Would allow a symbol to be selected from the drop-down list at the top of
the chart pane and would display it in a ?pad and aligned? manner (Missing
bars shown as dashes at previous close price, with volume at zero).
Would allow a symbol to be selected from the AA results window and have the
resulting Chart displayed again in a ?Pad and Aligned? manner.
(Behind the scenes there may need to be a process of setting up a reference
symbol , e.g. the Index, and then ?swapping? the foreign symbol (the index)
and the subject symbol. Anyway, this has been the approach I have been
working on with little success.)
Perhaps there is a better approach? As a new user of AmiBroker I feel as I
am constantly drinking from the fire-hose!
Any help would be appreciated.
Robert
