Re: [amibroker] AmiBroker 4.86.0 BETA released
Hi Tomasz,
Yes, I mis-wrote when I said the database disappears. It does not,
of course. But I had a heck of a time (finally successful) getting
the default database to show a chart upon opening. Using Window-New,
which I had tried several times, produces a chart of course, but
every time I shut down AB and re-opened it, nothing showing.
It has something to do with the default layout I guess, but as I
wrote I save everything upon exit, so maybe the problem was that I
exited with no chart showing, and that became a new default layout?
I didn't like this experience. ^_^ (And please, no more vertical
screen real estate snatching.)

Hi Tomasz,
If I do this: close the LAST (originally the only) tab, nothing is
saved. The database disappears, and reopening the program comes up
with an empty program, at which time I have to load a layout.
Surely this cannot be by design, and I have preferences to save

need to manually save it as default layout.

[amibroker] Nested if-statements
Hi!
I have a system that has a few indicators. I want to code this in
amibroker.
I want a buy signal when all of the indicators acts in a specific way.
When one of my indicators acts the way i like a variabel is set
to true (or 1), when all of these are true, i want the buy signal.
So when a,b,c, or d are == 1 then give buy signal.
Is this done like this with nested if-statements?
if (a == 1){
if (b == 1){
if (c == 1){
if (d == 1){
BUY-SIGNAL
}
}
}
}
Thanks!

Re: [amibroker] Nested if-statements
hi,
you can do it like that but in Amibroker you can
also work with arrays. So for instance:
constraint1 = ...;
constraint2 = ...;
constraint1 and 2 are both arrays that contain "0"
and "1".
allconstraints = constraint1 AND
constraint2;
now allconstraints is an array that carries the
values 0 when only 1 or neither constraint applies and it carries 1 when both
constraints apply,
So then:
Buy = allconstraints;

Re: [amibroker] Rename Window Tabs
One more improvement I see compared to all the
popular tabbed browser is making the tabs automatically resizable. The tab width
would automatically reduce when more tabs are opened so that more tabs can be
seen. The currently implementation just hide the tabs when about 5 has been
opened.

[amibroker] Unstable??
Hmmm. I really
got into the tabs with different symbols, time periods (intraday), etc.
Now, 1/2 hour in, the program is consistently locking up. End Task,
restart, lockup. End Task, restart, lockup. Numerous times to not seem a
coincidence. Have been running QT and RT AB for weeks and weeks now
without incident, including all day yesterday with latest version. Only
difference this morning was multiple window tabs open.
I had saved a bunch
(6) tabs in the Default layout, and this last time, I was able to call up
another layout without tabs. So far, no lockup.
anyone else see this
on intraday data? I am feeding the data with QuoteTracker if that makes a
difference.

Re: [amibroker] Unstable??
Ken,
You need to understand that you are not opening TABS. You are
opening CHARTS.
Each chart you open consumes computer resources.
And if you are opening lots of them and you work in real time
it means that all those extra
charts you have opened need to be refreshed when new data come
in.
And when you are working with QuoteTracker - yes it makes big
difference because
QuoteTracker link is HTTP (web based) which means that data
are transmitted in plain
web protocol which is slow. And if you do that for lots of
symbols it may lock up your machine.
So do not open extra charts/tabs just for fun. Especially when
you work with QT as data source.
Open them only when you really need them.
There is no need to put all the stuff open all the time. It is
definitely *not* good idea to
open extra charts just for different symbols/time frames when
you can have the same effect
by simply switching the symbol - consuming less
resources.

as currently structured.
If the buystop price is not exceeded during the day
(High not greaterthan
buystop) than the backtester will give me the Low of the
day as my filled
price.
I have tried any number of logic combinations and
can not achieve the
following.
If the high of the day is not greater than
buystop than I want NO trade to
occur. For the life of me, I can not achieve a
logic combination that
cancels the buy if this occurs. I can set the
price filled to be the days
open, high, low or close, but I can not cancel the
buy.
Any coding help would be greatly
appreciated.

What MDI is and how tabs relate to it. was: Re: [amibroker] Rename Window Tabs
No, you are completely missing the point about what MDI tabs
are and how documents are handled.
AmiBroker is multiple document interface (MDI) application. It
was ALWAYS like that !
Nothing changed in 4.86 in this area. To learn what MDI
is read that:
http://en.wikipedia.org/wiki/Multiple_document_interface
(
Now all those tabs are just an ADDITIONAL way to switch
opendocuments
(in addition to Window- menu where the list of open
documents is also available).
Previously to switch the documents you would need to use
Window menu.
Now in addition to that you can use tabs. But this is just
convenience feature.
(more info at: http://en.wikipedia.org/wiki/Tabbed_Document_Interface)
You need to understand that these are not "user definable
tabs" like chart sheets below.
These tabs are basically DOCUMENT WINDOW SWITCHER (like
Windows TASK BAR in the bottom).
And it works exactly using the same idea as Windows TASK
BAR
UsingWindows TASK BAR:
you OPEN THE APPLICATION - a new button in the task bar
appears
- and you can switch BETWEEN open applications using TASK BAR
buttons.
- you can not rename the button because it represents
APPLICATION NAME.
- and you need to be careful with opening too many
applications for fun because
all open applications consume system resources
Now using AmiBroker MDI tabs:
you OPEN THE DOCUMENT (chart) - a new button (tab)
appears
- you can switch between open applications usign buttons
(TABS)
- you can not rename the button because it represents DOCUMENT
NAME
- and you need to be careful with opening too many documents
for fun because
all open documents consume system
resources
The wikipedia links describing TDI / MDI are somewhat outdated
and AmiBroker actually combines
advantages of BOTH TDI and MDI approaches (for example you can
tile windowsin AB's TDI)

Since the
suggestions are flying fast and furious, how about the option of Renaming the
new window tabs just like you can with the Pane Tabs along the bottom.
Right click and type in your own custom name. If later, this conflicts
with new Document handling schemes, internally code some Tabs renameable and
others fixed.

Ken,
You need to understand that you are not opening TABS. You are
opening CHARTS.
Each chart you open consumes computer resources.
And if you are opening lots of them and you work in real time
it means that all those extra
charts you have opened need to be refreshed when new data come
in.
And when you are working with QuoteTracker - yes it makes big
difference because
QuoteTracker link is HTTP (web based) which means that data
are transmitted in plain
web protocol which is slow. And if you do that for lots of
symbols it may lock up your machine.
So do not open extra charts/tabs just for fun. Especially when
you work with QT as data source.
Open them only when you really need them.
There is no need to put all the stuff open all the time. It is
definitely *not* good idea to
open extra charts just for different symbols/time frames when
you can have the same effect
by simply switching the symbol - consuming less
resources.

the Hurst DE AFL I previously mentioned I would post ...
It INCLUDES
PolyFit.AFL, which you can get at the AB library, in order to do the
extrapolations.
Functionality
- You can plot up to
5 lengths ... This can be increased with the inclusion of one or two
statements if desired.
- Bands at the moment
are percentage oriented,but it would be relatively simple toallow
them to be based on StDev as well.
- Alwaysworks
up to the bar YOU select by creating CMA's ( my version, slightly modified for
additional smoothness ) up to n/2 bars ( Where n in the
CMA Length ) prior and then extrapolating
from that point on.
- Extrapolation will
always be at least to the bar you selectedand can be extended beyond
that by parameter selection.
- Band color change (
Dark to Light ) and Down / Up triangles show where CMA's end and Extrapolation
begins.
-The
extrapolation portion of any given band can of course change after the fact
for any given bar but once a CMA for a particular bar has been calculated it
is in essence frozen from that point forward.

Re: [amibroker] Re: FFT example (4.86 beta required)
Hello,
Yes it uses last value. But if you are after finding cycles
you have to assume anyway that given cycle will last at least a bit,
without such assumption there are no cycles :-)
So last value from say one year back should work forward.

Hello,
Here are few words about new FFT function.
It requires AmiBroker 4.86 BETA to run.
http://www.amibroker.com/devlog/2006/10/11/amibroker-4860-beta-
released/
===
FFT( array, len = 0 )
performs FFT (Fast Fourier Transform) on last 'len' bars of the
array, if len is set to zero, then FFT is performed
on entire array. len parameter must be even.
Result:
function returns array which holds FFT bins for first 'len' bars.
There are len/2 FFT complex bins returned,
where bin is a pair of numbers (complex number): first is real part
of the complex number and second number
is the imaginary part of the complex number.
result = FFT( array, 256 );
where:
0th bin (result[0] and result[1]) represents DC component,
1st bin (result[1 ] and result[2]) represents real and imaginary
parts of lowest frequency range
and so on upto result[ len - 2 ] and result[ len - 1 ]
remaining elements of the array are set to zero.
FFT bins are complex numbers and do not represent real amplitude
and phase. To obtain amplitude and
phase from bins you need to convert inside the formula. The
following code snipplet does that:
ffc = FFT(data,Len);
for( i = 0; i Len - 1; i = i + 2 )
{
amp[ i ] = amp[ i + 1 ] = sqrt(ffc[ i ]^ 2 + ffc[ i + 1 ]
^2);
phase[ i ] = phase[ i + 1 ] = atan2( ffc[ i + 1], ffc[ i ] );
}
IMPORTANT note: input array for FFT must NOT contain any Null
values. Use Nz() function to convert Nulls to zeros
if you are not sure that input array is free from nulls.
Below is example code showing how to use new FFT function in AFL.
SetBarsRequired(10,10);
Len = Param(FFT Length, 1024, 64, 1, 10 );
Len = Min( Len, BarCount );
x = BarIndex();
x1 = x - BarCount + Len;
input = C;
a = LastValue( LinRegIntercept( input, Len - 1 ) );
b = LastValue( LinRegSlope( input, Len - 1 ) );
Lr = a + b * x1;
data = input - Lr;// de-trending
ffc = FFT(data,Len);
for( i = 0; i Len - 1; i = i + 2 )
{
amp[ i ] = amp[ i + 1 ] = sqrt(ffc[ i ]^ 2 + ffc[ i + 1 ]^2);
phase[ i ] = phase[ i + 1 ] = atan2( ffc[ i + 1], ffc[ i ] );
}
auto = ParamToggle(Auto dominant cycle, No|Yes, 1 );
sbar = Param( Which FFT bin, 1, 0, 50 );
skipbin1 = ParamToggle(Skip 1st FFT bin, No|Yes, 1 );
if( auto )
{
sbar = int( LastValue(ValueWhen( amp == LastValue(Highest( IIf(
skipbin1 AND x 4, 0 , amp ) )), x / 2 )) );
}
fv = Status(firstvisiblebar);
thisbar = Ref( int(x/2) == sbar, -fv);
Plot( Ref(amp,-fv),amplitude (bin + Ref( int(x/2), -fv ) +),
IIf( thisbar, colorRed, colorBlack ),styleArea);
Plot( IIf( BarCount - BarIndex() Len, data, Null ) , de-trended
input (+Len+ bars), colorOrange, styleLeftAxisScale );
Plot( cos( phase[ sbar * 2 ] + (sbar) * x1 * 2 * 3.1415926 /

However, there are several points that should be mentioned or questioned with regards to your comments ... 1. It is clear from Hurst's course material that PM and the techniques therein were, in his mind, a fairly simplistic view of how he analyzed price and that the curvelinear trendlines were only a means for the analyst to discover the cyclic forces in play i.e. a possible first step in developing a full phasing Analysis ( FPA ) and using FLD's, VTL's and other techniques ... 2. As far as the tools and the math involved in the later chapters and appendicies it is also clear that Hurst not only employed the techniques therein but other more sophisticated techniques that he didn't really write much about in PM. Clues to this can be seen in the bibliography. 3. While PC's and AB didn't exist in 1970, mainframes and mini's did and if you recall we had already managed to get to the moon and back mostly by use of the slide rule. 4. The curvelinear bands that Hurst's uses are in essence n period centered moving averages with percentage or standard deviation bands around them which by their nature can not be computed closer than n / 2 bars prior to the current bar. As such one must have some technique for extrapolating those bands to at least the current bar and preferably beyond. Without this capability one would have already experienced half the move in the opposite direction when the CMA catches up. My question then is ... If you are using curvelinear bands of one sort or another inside AB how are you constructing the bands and what methodologies are you using to extrapolate them ? --- In amibroker@yahoogroups.com, Ton Sieverding ton.sieverding@ wrote: Hurst wrote 'The Profit Magic of Stock Transaction Timing' in 1970. When the technical annalist was using pencil and paper for his graphs. Bill Gates and TJ still did not exist and Hurst was not using a PC. I've tried to get the original version of the book but only got the reprinted version from 2000. Frankly I have the feeling that Chapter 11 as well as the Appendices have been added at the time of the reprint. This to give you my opinion how I see the book. It is an attempt to work with forecasted envelopes. And a good one ... For me the practical 'red line' for using the Hurst principle is as I told you already rather simple. Try to construct two trading bands. A long and a short period trading band. Hurst tells you how to do that with pencil and paper. The software today does it automatically for you. As soon as the short band is above the long one and the price above the short band you will have an 'overbought' situation. When the short band falls below the long band and the price is below the short band you have an 'oversold' situation. The combination of these 'overbought' and 'oversold' situations with a falling resp. rising long trend will give you the SELL and BUY signals.

I know using position score does this after a fashion , but I want
to
do it early on in the process.
i would also like to be able use this function in the explorer to
automatically generate watch lists. I know it no biggie to do it
manually using the sort columns and counting, But by the time I do
it
for several lists it takes a surprising amount of time.
Thanks for your help
Mark

I noticed after publishing this that it needed to have an additional

Here's the Hurst DE AFL I previously mentioned I would post ...
It INCLUDES PolyFit.AFL, which you can get at the AB library, in
order to do the extrapolations.
Functionality
- You can plot up to 5 lengths ... This can be increased with
the inclusion of one or two statements if desired.
- Bands at the moment are percentage oriented, but it would be
relatively simple to allow them to be based on StDev as well.
- Always works up to the bar YOU select by creating CMA's ( my
version, slightly modified for additional smoothness ) up to n/2
bars ( Where n in the CMA Length ) prior and then extrapolating from
that point on.
- Extrapolation will always be at least to the bar you selected
and can be extended beyond that by parameter selection.
- Band color change ( Dark to Light ) and Down / Up triangles
show where CMA's end and Extrapolation begins.
- The extrapolation portion of any given band can of course
change after the fact for any given bar but once a CMA for a
particular bar has been calculated it is in essence frozen from that
point forward.
There is then NO forward looking of this AFL ... It does however
purposely offset arrays so that it can plot beyond the last bar in
the chart.
See attached macro detailed views and afl ...
... ... ...

[amibroker] ExRem and Short/Cover
Can anyone tell me how to use ExRem to remove the extra buy/sell
signals when using different criteria for buy, sell, short and cover,
i.e. my sell signal is different than my short signal? The only
examples I could find just showed exrem for buy/sell, assuming

RE: [amibroker] ExRem and Short/Cover
It doesn't matter if Sell = Short, or not. All the function does is
remove redundant signals AFTER Buy/Sell/Short/Cover has been processed.
This way you can PlotShapes using Buy/Sell/Short/Cover and you will only
see the signals you would take.
Buy = ExRem(Buy,Sell); //Removes redundant Buy signals
Sell = ExRem(Sell,Buy); //Removes redundant Sell signals.
Do the same for Short,Cover

[amibroker] Can be coded without loop?
Hi
I wanted to plot some horizontal lines extending from successive hi and lo
pivot points. The code below illustrates the intention but does not work as
I guess IIF is evaluating the argument arrays prior to execution.
Wondering if there is a way to do this without looping? Basically need
method to propagate same value thru array until condition changes then
propagate next value...

[amibroker] Re: ExRem and Short/Cover
Terry, thanks for the reply. In my code I'm using:
Sell=ExRem(Sell,Buy);
Buy=ExRem(Buy,Sell);
Cover=ExRem(Cover,Short);
Short=ExRem(Short,Cover);
The problem I'm having is generating a series of signals like sell,
short, sell, short, without a previous buy or cover signal and I don't
understand how that could happen. I've tried different combinations
like exrem(Buy,sell+cover), for example, and I'm still getting signals
that don't make sense. Any idea how to fix that or are there any
programs that include different short/cover signals that I could copy?

right now it does not make too much sense (if any) because you don't

In the future releases AB will open not only chart document windows
but also other types of documents
and then it will make perfect sense to have these tabs.
If you noticed this
http://www.amibroker.com/devlog/2006/10/11/amibroker-4860-beta-released/
it says:
Promised new Account Manager functionality is still under
development and has been hidden/disabled in this release and it will
appear later in one of upcoming beta versions.
These tabs are just the extra feature that will used by new features
that are now HIDDEN from your eyes, because they are still
under development. As I wrote in one of previous e-mails, this beta
was released in-the-middle of development process because
of people waiting for built-in FFT function. So I had to hide some
in-development functionality but did not hide those tabs because I was
thinking
that they are pretty common ( at least among users of by today's
modern browsers like Firefox or Opera) and I was thinking that
they won't
confuse anyone.
So for time being - just forget that they exists.

Short=ExRem(Short,Cover);
The problem I'm having is generating a series of signals like sell,
short, sell, short, without a previous buy or cover signal and I don't
understand how that could happen.I've tried different combinations
like exrem(Buy,sell+cover), for example, and I'm still getting signals
that don't make sense.Any idea how to fix that or are there any
programs that include different short/cover signals that I could copy?

It doesn't matter if Sell = Short, or not. All the function does is
remove redundant signals AFTER Buy/Sell/Short/Cover has been
processed.
This way you can PlotShapes using Buy/Sell/Short/Cover and you will
only
see the signals you would take.
Buy= ExRem(Buy,Sell); //Removes redundant Buy signals
Sell = ExRem(Sell,Buy); //Removes redundant Sell signals.
Do the same for Short,Cover

This is great.Absolutely great. Now have to see it play out real
time to get a feel of how it gets along and reacts to price as new bars
come in to the chart. Thanks very much.

Functionality
- You can plot up to

statements if desired.
- Bands at the moment
are percentage oriented,but it would be relatively simple toallow
them to be based on StDev as well.
- Alwaysworks
up to the bar YOU select by creating CMA's ( my version, slightly modified for
additional smoothness ) up to n/2 bars ( Where n in the
CMA Length ) prior and then
extrapolating
from that point on.
- Extrapolation will
always be at least to the bar you selectedand can be extended beyond
that by parameter selection.
- Band color change (
Dark to Light ) and Down / Up triangles show where CMA's end and Extrapolation
begins.
-The
extrapolation portion of any given band can of course change after the fact
for any given bar but once a CMA for a particular bar has been calculated it
is in essence frozen from that point forward.

[amibroker] Options
I'm curious. Does anyone here have access to
options history data?
Can someone tell me what the Ask price was for the
stock SIGM for the October 17.50 call two days ago.
Here's the options symbol and date.
MQNJW
10 OCTOBER 2006
I was also wondering. Does AmiBroker have the ability
to chart options prices. If so, where would the data
feed come from? It sounds like a really cool feature if
AmiBroker could do it.
Thank you,

[amibroker] Re: Range Bars
I too am very keen to see Range Bars implemented in Amibroker. There
has already been a couple of suggestions opened in the the AmiBroker
Feedback Centre about this, (see #284 and #201). Range Bars, in my
view, are THE best way to eliminate noise in any market.
As an example of what Range Bars actually are, have a look at their
implementation in Fibonacci Trader in this link:
http://www.fibonaccitrader.com/HELP40/Range%20Bar/default.htm
Note that Range Bars are independent of time, the bar only closes
when the range has completed. Note also that (by definition) Range
Bars are all the same length, and properly implemented Range Bars do
not have any gaps.
Now there is no way I am going to use Fibonacci Trader over
Amibroker. Fibonacci Trader is about 5 or 6 times more expensive and
overall does not come close to AmiBroker in terms of ease of use and
functionality. Everyone has their own view as to what extra
functionality they would like to see added to certain software but I
believe many people would find Range Bars extremely useful.
Has anyone had a go at implementing Range Bars in Amibroker. I'm not
even sure it would be possble. Anyway, I think the best way would to
have them built into the Amibroker s/w.

[amibroker] Re: Can be coded without loop?
Hello John,
I came out of weekly hibernation on account of you being a gentleman
and a scholar.
Here is a small suite that fits nicely with Prakash's example.
I modified his code to make it consistent with my style (I prefer
bar charts to candlestick and generally overlay for this type of
*indicator*).
I haven't got around to doing the troughs.
They are the introductory modules for some higher level indicators
(still in the pipeline).
I hope they offer some help or stimulate some ideas that lead to
resolutions for you.

Re: [amibroker] Re: Rank a list in order
Assuming you need to sort them for each bar. You can code ranking to do this, but it does take a lot of time as each symbol must be compared to every other symbol for every symbol and every barYou can Osaka plugin or code it yourself, some examples I believe are in the library for sorting on the last (or selected) bar only. Need to modify these for creating array of results.
You could always pre-run the sort and store the results in composite symbols.The easiest is to just allow psoitionscore to do the work for you, not exactly the same but is simpler.-- CheersGraham

is it possible to generate code that will rank in order ie I want to perform a function ie take the ROC(C,10); take the top 25 and then perform further analysis only on these 25.
I know using position score does this after a fashion , but I wantto do it early on in the process. i would also like to be able use this function in the explorer to automatically generate watch lists. I know it no biggie to do it
manually using the sort columns and counting, But by the time I doit for several lists it takes a surprising amount of time. Thanks for your help Mark

execute AB, backfill again, then save database.
