Hello Herman,
Searched my saved messages and found below:
From 8/24/08;
The one and only correct way to force refresh of given formula
from the very same formula
is to use RequestTimedRefresh(). It refreshes ONE and only formula.
Using RefreshAll is huge overkill. It refreshes EVERYHING,
including all ticker lists, tree displays, dialogs, commentaries,
interpretations, etc.
There won't be any "Scope" added to RefreshAll because
it will be, like RefreshAll already is, abused. RefreshAll already
has protection against brining the program down by implied
infinite loops generated by people calling it from indicators unconditionally.
I can't stop people from shooting themselves in the foot, but I
can at least disourage using RefreshAll as much as I can.
Best regards,

Subject: Re: [amibroker] When does
AmiBroker execute RefreshAll?
I found one reference by Tomasz on the
feedback site:
Symbol list refresh is also triggered
automatically at the end of exploration if you use
the following functions:
CategorySetName
CategoryAddSymbol
CategoryRemoveSymbol
After using ATC in AA?
Can anyone complete the list?
With my DB (lots of categories and
tickers) each RefreshAll executed by AB (I do not call any RefreshAll()
myself!) takes several seconds and interferes with my OLE synchronization
protocol.
I want to prevent these RefreshAlls and am
considering substituting all AB WL functions with custom functions using Static
and Persistent variables, so that I can control when the AB RefreshAll takes
place. To do this I need to know which AB operations trigger the refreshes.
Anyone been this road?
thanks,
herman

Sorry, i know
the answer was posted by Tomasz but i can't find it.
I need to know
'ALL' conditions that trigger an AmiBroker RefreshAll.
Would anyone
know where this was posted?
Many thanks,
herman
