[amibroker] Can multiple Chart panes be created from an AA Backtest .afl?

Hi all,

 

What I would like to achieve, if at all possible, is to create a multi-pane chart (or perhaps a multi-chart layout) from within an .afl used in the Automatic Analysis  Backtest process.

 

With “Automatic Analysis”  Back-testing I have developed code that back-tests effectively and I use the AA Editor/”Apply Indicator” buttons to display a single chart with indicators and buy/sell arrows.   I have also used Layouts to display a composite indicator of system results created from within the .afl using the “AddToComposite” function.

 

But as yet, I have found no way to either create a multi-pane presentation or to populate a pre-existing layout with “live” data from an .afl being used in the AA back-test process.  I want to be able to show details of a “Foreign” symbol in a separate pane and several other .afl components, such as liquidity, also in separate panes.  All of this can be easily done in saved Layouts (.aly or .chart) using “drag-and-drop” type code but this is quite separate to the code used in the AA window.  (I am trying to avoid having similar code in two places and so avoid potential update errors in future).    

 

·         Is it possible for AA .afl Plot statements (or similar) to create separate, and sized, Panes within a blank chart?

·         Is it possible to direct AA .afl Plot statements to separate Panes within a pre-written and/or pre-loaded layout window? 

·         Is it possible to pass variable values from an AA .afl to a layout (either already open or to be called)?

·         Is a COM object approach possible? (Joe Landry, 22 Jan 08, gave me some script tips but I have not been able to get anything working – and the Manual is very “brief” on this subject).

 

All help would be greatly appreciated, even if it is to confirm that it is not currently possible in AmiBroker.

 

Regards,

 

Robert
