Whitney - Note that you're indexing the retrieval of fcum with i and but
your loop is written for f.
When I changed it I do get values and not zeros. Which was your question
in the first place.
<<<<<<<<<<<<<< changed the index on the variables fcum>>>>>>>>>>>>>>>>>>>>>.
Cumfarray = Cum( farray );
for (f=fv; f<=Lv; f++)
{
_TRACE( "farray = " + StrFormat( fi, farray[f] ) );
fcum = Cum( farray );
_TRACE( "fcum = " + StrFormat( fi, fcum[f] ) );
}
_TRACE( "lastval of farray after foreign = " + StrFormat( fi, LastValue(
fcum ) ) );
Buy=Sell=0;
There are no persistent arrays other than writing it out to 1) file..fputs
fgets, 2) using the ODBC
interface to Access/SQL Server or 3)using the Osaka plugin as a datastore.
I've used all three in
very basic ways. Osaka mostly for sorts, Access to store positions, no of
shares, etc. basic portfolio
work to generate an equity curve. There are persistent numbers and text
store AFL functions...
VarSet VarGet for numbers and text. These I understand will persist from
routine to routine unless
you close Amibroker.
You could write your approach in one long script I suppose and should be
able to read the intermediate ATC as the script that I sent does. For some
of the work I do where I build on intermediate results, I use jScript to
drive say - in one case 5 AFL scripts, with each one building on the other.
Here I use ATCs function to store intermediate and final averages and equity
curves as different SCANs are run. There's a utility by Fred Tonnetti in
our files called BatMan that will do the same thing and you won't have to
learn about and how to use jScript objects.
We've asked for persistent arrays but it's not a straight forward add on as
I understand it.
