[amibroker] Handling Missing Bars in a complex Chart layout



PureBytes Links

Trading Reference Links

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
