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."

5.23.0 BETA released
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
