Hello,
 
Yes it is intended. Optimization params are not built-in columns.
They are USER-defined columns that vary from optimization to optimization (because number
of params does change).
 
Read Me says:
 
"Storing column state [ ... ] The widths, ordering and visibility of all built-in columns in automatic-analysis is stored between runs."
 
 
BUT THEN...
 
"AFL: SetOption("ExtraColumnsLocation", col) - this new option allows the user to change the location of custom columns added during backtest/optimization
 
"extra" columns mean:
a) any custom metrics added using custom backtester
b) any optimization parameters defined using Optimize() function
 
If both custom metrics and optimization parameters are present then
custom metrics appear first then optimization parameters
 
This function is provided to allow the user to change the default "at the end" location of custom columns/optimization parameters.
For example
 
SetOption("ExtraColumnsLocation", 1 );
 
will cause that custom metrics and opt params will be subsequently added starting from column 1 (as opposed to last column default)
 
Note that this setting changes "visual" order of columns, not really in-memory order or export order, so
exported data files or copy/paste format do not change."

In AA Optimization Mode the parameters being optimized will not stay in position set in Column Setup. For example, moving the parms to say the first columns and then running the same optimization (full optimization) results in the parms columns being repositioned to default position at end of window.
Is this as intended ?
Thanks
Dave

Hello,
 
AmiBroker 5.23.0 BETA released
 
CHANGES AS compared to 5.22.0
- Font used by progress window, string input, tip of the day, search file is now “MS Shell Dlg” (the same as elsewhere in AB) that means that is CoolType friendly (TTF)
- AFL: SetOption(”ExtraColumnsLocation”, col) - this new option allows the user to change the location of custom columns added during backtest/optimization
- Implemented hiding columns in all list views (right click over list view HEADER to bring “Setup Columns” dialog)
- Storing column state (widths/ordering/visibility) in automatic analysis implemented
- Data Window implemented (available from View->Data Window menu)
- Home key was working incorrectly when more than one pane was used in the chart. Fixed
- Implemented simple performance monitor Tools->Performance Monitor
- Time&Sales window now shows some “recent statistics” regarding trading
 
Among other things you can now hide selected columns in all list-views,
by clicking with right mouse button over list-view header and choosing "Column Setup".
In the setup dialog you can uncheck any column to hide it.
