Tomasz,
The broker.params file is 117KB and you are right it contains
thousands of parameters from past versions of the chart.
Since I keep all my parameters in separate files I deleted this file
and it is now only 5KB and my program runs the same (I made a copy
first).
How interesting. Could this have slowed down applying my edits as it
grew?
I could just delete this file from time to time. Does it serve any
other purpose?
Best regards,
Dennis
