Hi all,
i know i'm at
beginner levels but i just wanted to give my feed back to those that helped
me,,,and have to admitt i'm still learning the code and taking bits from here n
there without fully understanding it all,, but i've got my 3 day swing
exploration working at this stage and it kinda feels good :) ,,,
i've now subscribed to premium data eod for the asx and usa
stocks i explore one of the cfd watch lists ,i've also noticed i can explore
with n=1 function or a 5 day range which returns more scans with a little
noise.
there's probably easier ways of doing it but here
it is,,any comments welcome.
cheers
Paul
Filter = C > 1 AND C < 20 //looking for bang for buck value
AND RecentHi3Is20= Ref(H,-3)==HHV(H,20)
//looking for 3 day hi to
be highest in 20days
AND recenthi= Ref(H,-1)<
Ref(H,-2) //looks for 3 lower highs
AND RecentHi= Ref(H,0) <
Ref(H,-1)
AND MAproperOrder= IIf(MA(C,18)>MA(C,40),1,0) //trend definer
AND MAproperOrder= IIf(MA(C,40)>MA(C,41),1,0) //attempt to ensure 40ma pointing up
AND recentLow= Ref(L,0) <
Ref(L,-1) //trying to ensure a new high creates an
isolation
AND recentlow= Ref(L,0) <
MA(C,18); //trying to ensure
some reversion to the mean
AddColumn (C,"close");
//needed a column for
exploration
AddColumn (V,"Volume");
//add on bit of
fun.
Paul,
The failed to
initialize a variable error
In most cases it seems that Amibroker requires that you give the moving averages a
variable name or use a logical iif statement to
assign a value from a comparison.
Try this for the most
straightforward way I can think of.
T=MA(C,20);
F=MA(C,40);
Filter=T>F;
This should do an
exploration for that one factor on whatever list you have selected or filtered
on the left side of the automatic analysis window.
Filter statement must
come after defining MA proper order. Code isnt smart
enough to look forward to see that you will define MAproperOrder in a later
statement.
Filter= MAproperOrder >0;
MAproperOrder = iif(MA(C,20)>MA(C,40),1,0) ;
.. this is the logical iif statement to get MAproperOrder defined.
So you can try it
this way. You have to use an iif
(2 is in iif) statement
in order to combine the logic the way you wanted to and get your variable
defined with a value. You were writing a logical statement, so it requires the
iif statement, I believe. The
iif statements are the same as Excel formula
format.
MAproperOrder = iif(MA(C,20)>MA(C,40),1,0) ;
Filter= MAproperOrder >0;
Hope this helps
its hard jump starting any new programming language,
but I can assure you that Amibroker is efficient
with their code and its rational. And its compact compared to some of the other
systems. Im working to think like it thinks
.. its generally more logical than I am
. Hard on my brain some days. Im a rookie
as well as you. Takes a while and what I think will work,
wont necessarily. And it seems that your code should work,
but this probably will. The pros here can make this stuff
work with a lot of combined expressions, but I stick with one step at a
time.

Subject: Re: [amibroker] mentor
wanted
thank you for your input and my apologies for my post being so
confusing,,
i'm not going to pursue assembling such a
basic swing filter any longer but my sincere thanks for your
time,
all the best with your trading and
interests
It is hard for me to understand your question but if
you want a signal that the high 3 days ago was the highest in the last 20
days, you might think about something like
this:
RecentHi3IsHi20=ref(H,-3)==hhv(H,20);
I've started reading the tutorials but i'm not
finding what i want to see,,,
i'd like to put together a simple
swing scan/explorer based on Oliver Velez
swing trading
tactics,,,
a 20ma above a 40ma ,,the high of 3-5 days ago the
highest high in 20 days
,,,the 3-5 days of down to have lower highs
looking for a new higher high
for the buy with the stop under the last
isolation low /pivotpoint
with ezyanalyser i can have all but 1 of
those indicators done in
seconds,,,the 1 i can't have is the 20ma
above the 40 ma,,for some reason
ezyanalyser looks at the ma of 20
days ago,,,and hence why i wanted
amibroker,,,with the bonus of
everything else amibroker does,,,,not to
mention the company of some
mind boggling posts from this user group.
alas learning this
language is more complex than studying Bradley Cowan's
4th dimensional
market geometry,,
hunting around through other filters in the
library and reading the
tutorials,,,which are great but i'm not
interestedin buying a ma cross over
or macd,,,nor in backtesting at
this stage,,,but i do need your help or
someone to mentor me through
this swing scan/explorer
this is where i'm at ,,i've tried pinching
this from a swing scan in the
library but changed the ma values to
what i want,,so i can atleast get part
of this swing filter
together,,
MAProperOrder = (MA(c,20) > MA(c,40));
post this i
get a "variable" error ,,,after some reading and looking through
other
files i now have
Filter = MAProperOrder before the other line,,,that
error has now moved to
error 29 ,,needs to be initialised,,,as
i've mentioned in another post on
Gartleys ,,i've looked up error 29
and read the example but fail to
understand how that apply's to this
situation also,,
next i need to be able to set the high of 3 days
ago to be the highest in 20
days,,,anytips on where abouts in the
tutorial i can read up on the language
used set this up
please,,,,
regards
Paul
