array - vbscript or jscript
Hello,
PositionScore does work on watch list as well and
allows to enter trades being within top 80% of your rank.
How?
Let's assume you watch lists consists of
100 symbols.
You set the FILTER in AA to contain only your
watch list,
and
use
SetOption("MaxOpenPositions", 20 );
PositionSize = -5; // 5% = 100% / 20
positions
20 open positions out of 100 symbols
represent exactly symbols that are ranked 80% and more.
Best regards,
Tomasz

Subject: [amibroker] Sort and rank an
array - vbscript or jscript
Hello
I
was wanting to sort and rank an array of all the symbols and corresponding
value, example RS or close, in a watchlist.
I have knocked together an AFL script that does this, using
example code from the AFL library, however it is incredibly slow on a
watchlist of 300 symbols.
I was
wondering if it was faster to do this using jscript (sort method?) or
vbscript (quick sort
algorithm ?), and if example code could be provided.
Also I realise on the Amibroker library there is an example
of both sort and rank, but there appears to be no doumentation on how to use
this in the library or in the mailing
list.
I realise there is
positionscore, however it does not appear to do what I require in this
instance, to me it only appears useful when you are comparing a few
securities with each other, and it does not rank an entire watchlist,
filtering a trade to within the top 80% of a value based on
rank.
Regards
Dave
