[MAS-discuss] New operators, requests for more operators

[Jim C. <jt...@di...>]

All -

I have just added several new operators (objects used to dynamically create
new TA indicators):

floor
ceiling
sine
cosine
tangent
arccosine
arcsine
arctangent

Those who have delved into creating their own indicators may be interested
in obtaining the latest executable, which provides these new operators.
I'm hoping to put a new release up on sourceforge soon, but if you don't
want to wait for that, let me know and I can send you the executable.
Make sure you let me know whether you want a version for Linux or for
Windows.

The other purpose for this email is to ask for requests for new operators
that you feel are needed.  I can't guarantee, of course, that I will have
the resources to implement all requested operators, but your feedback
could bring to my attention useful operators that I have overlooked so
that I can add them.  The goal, of course, is to keep increasing the
functionality and power of MAS until it becomes one of the most powerful
and useful TA systems available.

Here is a list of all the currently implemented standard mathematical
operators - to help prevent requests of operators that already exist:

and_operator
eq_operator
equivalence_operator
implication_operator
or_operator
xor_operator
ge_operator
gt_operator
le_operator
lt_operator
not_operator
false_command
true_command
absolute_value
addition
subtraction
multiplication
division
cosine
sine
tangent
arc_cosine
arc_sine
arc_tangent
ceiling
floor
log10
log2
log
n_th_root
power
rounded_value
safe_division
square_root

(There are other operators that focus on market-data-related operations,
but I don't want this list to get too large and confusing.)

Actually, CL_Client is a command-line client written in Java.  If you
want to run the GUI you need to run MA_Client.  But java is not finding
the class file, which if I remember right is because the gui class files
are now in the file mascharts.jar.  You could try this:

Start the server and then start up cmd.exe.  Make sure you're in
C:\Program Files\mas1.6.6q\lib\classes (assuming that is where the java
*.class files were installed).  Make sure there is a mascharts.jar file in
that directory.  (The name might be slightly different - you could search
for *.jar files.)  If it's not there, use the find file tool to find it and
cd to that directory.  Then run:

java -cp .\mascharts.jar MA_Client localhost 18273

(assuming mascharts.jar is the right file name and 18273 is the port number
the server is running on).  If this works, it should not be hard to modify
the batch file to do the same thing and get it working.

Since connecting to the server works in command-line mode, it should also
work for the GUI, assuming the parameters are the same as when running in
command-line mode, e.g., using localhost as the host name and the same port
number.

Hope this helps.

Re: [MAS-discuss] Access Denied

[Mikael R. <mik...@fr...>]

Hello,

Effectively I have windows XP SP1 installed on my computer, and I'm a 
french guy.

I've looked a bit into MAS to try to understand what is going on and 
I've see that the environments variable were not defined 
(%MAS_DIRECTORY% and %PATH%.

I'm not using the administrator account but I use an account with 
administrator rights so I don't think it is the source of the problem.

I've installed the version 1.6.5 of MAS and I was able to run the server 
(file mode) and the GUI client.

After that i've modifed the environment variable of MAS to point on the 
version 1.6.6q and I was able to run rhe server file. But when I've 
launched the guiclient I've got the following error :

C:\Program Files\mas1.6.6q\lib\classes>"C:\Program 
Files\mas1.6.6q\bin\runmasgui.bat"
C:\Program Files\mas1.6.6q\lib\classes>rem Run the mas GUI - connect 
with the se
rver started with runmas
C:\Program Files\mas1.6.6q\lib\classes>rem If a parameter is passed in, 
it will

C:\Program Files\mas1.6.6q\lib\classes>rem otherwise a hard-coded number

C:\Program Files\mas1.6.6q\lib\classes>java MA_Client localhost 18273
Exception in thread "main" java.lang.NoClassDefFoundError: MA_Client

The problem come from a syntax error in the script runmasgui.bat because 
the class filename is not MA_Client but CL_Client.

After I've modified the batch file I was able to run MAS in command line.

However in GUI mode there is always an access denied error. I think the 
problem is that the client can't connect to the server. I will make some 
other tests later.

Regards.

[MAS-discuss] Access Denied

[Mikael R. <mik...@fr...>]

Hello,

I've just installed MAS 1.6.6q on my windows computer and when I run it, 
I can see the standard windows of MAS and an another which said "Access 
Denied".

It's the first time I try MAS. I've installed the last JRE I've found 
1.4.2_05.

Can you help me ?

Regards.

MA_Client.class should be there, residing in a jar file.  The file's name
is mascharts.jar, if I recall correctly.  (You can list the file's contents
with:

jar vft mascharts.jar
)

How are you trying to start the GUI?

[MAS-discuss] MA_Client.class

[Mike L. <ml...@ya...>]

A'm I wrong or is MA_Client.class missing from the latest release.  When I try
to start the gui on a linux error, I get a message saying MA_Client.class is
missing.  Sure enough, it's not there.

Any suggestions?

Thanks,

Mike

That's probably a good idea.  Are you also using a firewall to keep out
unwanted network traffic?

Which version of mas are you using on Windows?

I don't think there is documentation describing how to run the GUI client
on Windows against a server process on a Linux machine, at least not
directly.  Probably the most reliable way to do it is to run the GUI from
the command line.  To elaborate on my earlier example (assuming you have
java installed):

Find the directory in which the file mascharts.jar resides and, with the
DOS command line (cmd or command), cd to that directory.  Then do:

java -cp .\mascharts.jar MA_Client hostname 2929

where hostname is the hostname of your linux server and replace 2929
with the port number with which you started the mas server.  (If you
don't have mascharts.jar, you're using an earlier version, in which
case the startup command will be a little different.)  If this doesn't
work, let me know what went wrong and I'll try to help.  (There could be
environment variable problems, etc.)  Post to the list - if I'm not able
to find the time to respond, someone else who can help may be able to.

Also, an easier way to test, to just make sure you can send requests from
your windows machine to the mas server, is to run macl:

Find where macl.exe resides and do:

.\macl -h hostname 2929

and see if the server responds with an command-line option menu.

Good luck!

Re: [MAS-discuss] Another New User

[Mike L. <ml...@ya...>]

Jim,

Thanks for the response.  My main requirement at this time is ease of use,
simply because I'm still a novice.  For that reason, I intend to run the server
as a daemon on my linux box.  I'm generally concerned about security though, so
I'll probably try to run it in a chroot jail.

I would like to be able to simply start the client on my PC and be operational.
 I didn't find a doc on command line options.  Did I miss it?

Thanks,

Mike

[MAS-discuss] Another New User

[Mike L. <ml...@ya...>]

Greetings,

I'm new to MAS and technical analysis in general.  I just have a few technical
questions about the install I hope someone can help me with.

I have a linux servre that runs all the time.  I would like to run the server
portion on it, and run the client on my PC.  I've looked at at the docs I can
find and can't find anything regarding the port number mas uses.  Does anyone
on the board know?

Obviously I'm running with the assumption that it is better to have the server
portion running most of the time.  I would also be interested in hearing if
this assumption is correct.

So far though, it looks pretty cool.  I'm looking forward to getting into it a
little.

Thanks,

Mike

[MAS-discuss] Yahoo address change problem/solution

[Jim C. <jt...@di...>]

Those of you using the -w option to get data from yahoo.com may have run
into this problem lately.  They appear to have changed the address for the
http data server from chart.yahoo.com to ichart.yahoo.com, causing data
retrieval to fail.  The solution is simple: Just change the line in the
mas_httprc file from:

host	chart.yahoo.com

to:

host	ichart.yahoo.com

(Make sure the separator between 'host' and the address remains a single
tab, no spaces.)

Re: [MAS-discuss] Workaround for "custom indicators in GUI"-problem

[Pedro P. <ped...@ho...>]

The problem in that case seems to be the ever pesky issue of unix/msdos 
based carriage returns, since unix ones only have the 0x0a hex and msdos 
have both 0x0a followed by 0x0d per carriage return. A "quick" solution 
to this in the future is to run the file through some msdos/unix 
converter which changes the carriage returns from one to another. I'm 
not exactly sure which ones there are for windows though. Also all this 
stems from the .ma_clientrc file I believe since that's what's sent 
through the network to the server with those carriage returns so that 
would be the file you want to be looking at.

Best regards,
Pedro

[MAS-discuss] Workaround for "custom indicators in GUI"-problem

[<pb...@ch...>]

Hi everybody!

You remember my mail from 2004-06-08 concerning my "adding custom indicator to GUI"-problem?

Good news: i found a workaround for this strange problem - looks like there is a little bug in the
Windows-executeable of MAS 1.6.6r.

I did a lot of network-tracing between client and server (both on WinXP) and compared it to the
communication of the Linux-version. So i found the following:

- the GUI-client starts up

- after clicking on 'Indicators' the client seems to request all available indicator names from the
  server

- the server sends the names in one TCP-frame

- each indicator name is delimited by a 0x0A-Byte
  each data-sequence/frame is terminated by a 0x07-Byte
  (see part of network-trace below - SMA20 at the end is my test-indicator)

0x0270   20 54 68 61 6E 20 6F 72-20 45 71 75 61 6C 20 74    Than or Equal t

- ONLY the names of custom indicators are additional delimited by a strange 0x0D-Byte

- the client receives this "unlucky extended" names & compares it with the content of .ma_clientrc

- needless to say, that the names are not matching -> custom indicators are not displayed
  (of course, in .ma_clientrc there are no trailing 0X0D-Bytes!!!)

From my point of the view, the error should be located somewhere around the creation of
new indicators via the command-line client (input of the indicator-name or so).

My humble workaround: if you add the indicator's name to .ma_clientrc, add a trailing 0x0D
(ASCII code 13) to the name. Now the names are matching and your new indicator is correctly
displayed... hope so! :-)

[MAS-discuss] Problem starting mas GUI - linux

[<ja...@mc...>]

Hello all, I'm a noob with MAS.  I've been able to start up the server ok with 
the option to get yahoo data.  When I try to start the client, I get: 
 
Server error: Error occurred retrieving non-intraday period types for a 
 
I'm missing something simple, right?  Someone please tell me what it is.

[MAS-discuss] Adding custom indicator to GUI

[<pb...@ch...>]

Hi everyone!

I've a strange problem adding a custom indicator to the Java GUI.
Maybe there's someone out there, who has the same troubles... and maybe
she's/he's a little bit wiser than me :-)

Case 1
- installed MAS 1.6.6q on Windows XP Pro
- created simple new indicator called "Philipp" (SMA 20)
- added new indicator to .ma_clientrc as described in the FAQ (keep file in UNIX-format, etc)
- started the server in file-mode
- started command-line client, indicator works fine
- started GUI client, indicator not displayed under "Indicators"

Case 2
- tried the same with MAS 1.6.6r on Windows XP Pro
- in this case i started the server in web-mode (retr from Yahoo) - works perfect!
- started command-line client, indicator works fine
- started GUI client, indicator not displayed under "Indicators"

Case 3
- installed MAS 1.6.6q on Linux (SuSE Linux 9.0)
- created same new indicator called "Philipp" (SMA 20) on Linux server
- started the server in file-mode
.....and now it's getting interesting......
- started GUI client on Windows XP-Client mentioned in Case 1 & 2 and connected
 to the MAS server running on the Linux box
- indicator "Philipp" is displayed under "Indicators"!!!

Now my humble question: in all 3 cases the Java GUI reads the same .ma_clientrc on the
Windows-client - why new indicator is only displayed correct, when connecting over the
network to the Linux server???

Local attempts are still failing (MAS server & client on same WinXP machine)
I didn't change .ma_clientrc between the tests.

Any help would be appreciated - thankx a lot!
Philipp

Hi Terry.

Most likely you have run into the "yahoo http comment bug" - yahoo added
http comments to its data, which mas doesn't expect.  The fix was
easy, but I've not yet formally released the compiled executable.

I'm hoping to find the time to put it up on sourceforge in the next few
days.  If it doesn't show up in a few days, why don't you send me a
reminder email - in case I don't get a chance to get to it.  At that point
I can just email you the new executable so you can get going with it.

[MAS-discuss] Mas

[Terry H. <ter...@bi...>]

Hi All, 

 

I am new to mas. It appears to be just what I was looking for. Hats off to
Jim! 

 

I only have one issue. I can not get the gui to run on my Linux box or Win2k
either when I connect the server to the web. I can run the server on both
boxes using the sample *.txt data. The gui works fine. I can run the server,
with know errors connecting to charts.yahoo.com. With the server connected
to yahoo the gui gives me a segmentation violation with an error explanation
of something like "Error occurred retrieving trading period types for aa".
It use to say "for a", but I edited the symbols file. 

 

I would really appreciate any help. Probably an error on my part. Thanks in
advance.

[MAS-discuss] Tip: How to avoid the persistent settings compatibility problem

[Jim C. <jt...@di...>]

I may have mentioned this before in this forum, I can't remember for
sure, but it seems that a lot of mas users are not aware of this issue
and I think posting it here will be helpful, since following this tip
could help save people some time and irritation.

The issue is that sometimes a new version of the mas executable will not be
compatible with respect to the saved indicators and market analyzers (the
indicators_persist and generators_persist files).  However, preventative
action can be taken to avoid running into this problem.  It's described in
the FAQ entry copied below.  (The FAQ is at:
http://eiffel-mas.sourceforge.net/support/FAQ.html
.)

I recommend that everyone who creates their own indicators or market
analyzers get used to using this technique for creating and editing
indicators and analyzers, so that you can avoid compatibility issues in
the future.

Here is the FAQ entry:

I updated to a new version of MAS and when the server starts up it
prints the following error and exits: "Retrieval of indicator library
file indicators_persist failed. The file may be corrupted or you may
have an incompatible version." How can I use the old indicators I have
created with the new server?

This problem occurs when a new version of MAS incorporates a change to
the structure of the indicator code that is not compatible with the old
version. As a result, the old indicator file, indicators_persist, cannot
be loaded when the new version of the server starts up. Once this occurs,
the only way to use your old indicators is to keep using the old version
of the server. (This problem can also occur with market analyzers and
the generators_persist file.) However, there is a preventative method
that can be used to overcome the problem: Whenever you create a new
indicator, start the server in the background (-b option) and use the
command-line client program, macl, to talk to the server and "record"
the conversation with the command:

macl -r output_file <portnumber>

where output_file is the name of the file to which you wish to save
the recorded output and <portnumber> is the port number with which you
started the server. Keep this file in a safe place. It would probably
also be a good idea to keep it backed up.

Whenever you upgrade to a new version of MAS and get the above error
message, you can restore the indicators you have created by running the
following command on each of your recorded output files:

macl -i file <portnumber>

where file is the name of a file created earlier with the -r option
and <portnumber> is, again, the port number with which you started the
server. This solution works for both indicators and market analyzers.

Note for Windows users: Starting MAS the "normal" way, by clicking on the
MAS icon, will execute the necessary step described above of starting
the server in the background. However, you will still need to run the
'macl -r ...' and 'macl -i ...' commands described above from the Windows
command line. Those who do not know how to do this may want to wait for
a future release in which this procedure is handled automatically.

Hi Lew.

(I'm CCing this email to the discuss list since others may not be aware of
the problem and may find it helpful at some point.)

There's a good chance that this problem is addressed by the following
FAQ entry:

http://eiffel-mas.sourceforge.net/support/FAQ.html#data

Here's the text of the issue, for your convenience:

I'm not able to view daily data in the charting GUI - only periods of
weekly intervals and longer are viewable.

Most likely you are not able to see daily data on the chart because
the start and end dates for daily data configured in the GUI do not
fall within the date range of the data you're using (for example, the
last date in your data is 1/2/2002 and the start date is configured as
12/1/2002). To fix this, either update your data so that it includes
data up to the current date (or last trading day) or change the start
and end date settings for daily data in the GUI.


Let me know if this solves the problem you're having.

Dear Jim Cochrane

Just downloaded MAS and have struggled to install on WIN XP.

I live in Ottawa, Canada.

My current roblem is that the GUI screen is blank immediately after
linking to Java.  mas-1.6.5 + mas-1.6.6g, but problem is
also present with 1.6.5 alone.

[MAS-discuss] About the new mas executable

[Jim C. <jt...@di...>]

To those who have run into the yahoo data problem and would like the fixed
executable (mas 1.6.6r), I probably won't get around to putting it up on
sourceforge for a while.  But if you would like to get hold of it before
then, just send me an email letting me know and I'll send you a email with
the compressed executable attached.  You should be able to just uncompress
it and replace the old mas executable with this one (though I'd recommend
backing up the old one first, just in case).

I have an "official" Linux version available to send out.  For those using
Windows, if I get enough requests (enough probably meaning some number
larger than one), I will probably have enough incentive to boot up
my NT machine and compile a Windows executable.

Note: If you use the new version you may run into a compatibility
problem re. the indicators_persist and generators_persist files.  If so,
you should read the FAQ entry about that (which I have copied below).
It won't solve the problem if you already have it, unfortunately, but
it provides a method of easily dealing with the problem in the future.
(Yes, this is a weakness of the design of the system that I hope to
address sometime in the future.)


Jim


Here is the FAQ entry about the *_persist files:


I updated to a new version of MAS and when the server starts up it
prints the following error and exits: "Retrieval of indicator library
file indicators_persist failed. The file may be corrupted or you may
have an incompatible version." How can I use the old indicators I have

and <portnumber> is, again, the port number with which you started the
server. This solution works for both indicators and market analyzers.

[MAS-discuss] Re.: The yahoo data bug has been fixed.

[Jim C. <jt...@di...>]

Note:  In my previous email where I suggested that anyone interested in
the fixed version should let me know, I neglected to mention that you
should also mention what platform - that is, Linux or Windows - you are
using.  This will allow me to gage the urgency of releasing an executable
for each platform.


Thanks.

Jim
