64 bit version Dukascopy Forex tips with Bitcoin crypto addition

64 bit version Dukascopy Forex tips with Bitcoin crypto addition

This is correspondence from some very knowledgable in Dukascopy JForex on tips for Memory, Installation, and surprise Bitcoin trading


1) JForex heap space
it says min. RAM 1GB here: https://www.dukascopy.com/swiss/english/forex/trading_login/
But it is too little most of the time.

Do you use 64 bit Java ?
Have you increased the heap size?
Probably you have, but just in case here come my instructions on this topic

—> I have done this which helps


2) Allow more memory usage of JForex
Don’t use the installed JForex, use Launch JForex 3 (No-installation) instead!
To increase the memory you have to edit the JForex start file, which you get from this website if you click on “JFOREX DEMO START”: http://www.dukascopy.com/swiss/english/forex/trading_login/marketplace_demo_login/
You can use the right mouse botton to save the file to a destination where you can find it. From there you should be able to edit it.

Here is everything in detail:
a) First of all please check your operating system. It has to be a 64 bit operating system.
b) Then check your Java version. It has to be a 64 bit version. If not, deinstall your current Java and install the 64 bit version. You can find it here: http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html
download the latest JRE 7, 64 bit version: Windows x64 . Take Java 7 as it is better tested with JForex. But it should run with Java 8 as well.
c) Instead of running JForex from dukascopy.com, you have to download the jForex.jnlp file on the hard drive and edit it as mentioned above.
d) Open the jForex.jnlp file and search for the following line :
<java version=”1.6+” initial-heap-size=”32m” max-heap-size=”512m”/>
e) Edit it and set the max-heap-size to 1512m or more. This gives JForex 1.5 GB of max. memory or more.
f) Then run JForex from the modified jnlp file on your hard drive by a double click. Log in.
g) Be aware: when Dukascopy makes JForex updates, you might have to download the new jnlp file again and redo the previous described steps.

 

-> Have not tried but prefer to run the downloadable self running without the JNLP option


You might then see that JForex uses way more memory than 700 MB, e.g. while back testing, you will see this usage in the task manager.
You can also watch your current JForex memory consumption in JForex by activating the box “Show Java memory heap”, you can find this in Menu Tools->Preferences->Advanced.

3) Running serveral JForex
Have you ever tried to open several JForex on the same account.
This shares CPU cores and should increase speed.
Maybe you should open 10 instruments per JForex. Subscribe only to instruments, which are used in the opened JForex.
—> that would be useful but a wonky programming trick. Would it not just be better to have more RAM on a server while watching more instruments? e.g. in my case 40 to 60+

—> Not bad so congrats on that. I am getting more comfortable but i may do topic of it next Monday


6) BTC/USD on Dukascopy
Have you also detect Bitcoin mentioned here:
https://www.dukascopy.com/swiss/english/forex/jforex/forum/viewtopic.php?f=113&t=56002
https://www.dukascopy.com/client/javadoc3/com/dukascopy/api/Instrument.html#BTCUSD
Seems they get ready for Bitcoin and Ethereum.

—> This is HUGE so thanks for these notes

Quant Hiring and Friendly Tips

 

ha ha insider traders are now high speed traders. I quote:

  • High-speed traders who have the technology and skill to plausibly believe that they can react faster to news than the rest of the market;

  • Low-speed traders who understand that they do not have the technology or skill to react faster to news than the rest of the market, and so do not attempt to trade rapidly in response to news; and

  • Idiots.

  • For we are idiots?

Tips to build wxWidgets C++ for Ubuntu Linux with Codelite IDE

Tips to build wxWidgets C++ for Ubuntu Linux

Here are some notes to help 


https://www.wxwidgets.org/downloads/
../configure --enable-unicode --enable-debug

configure: error: 
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.

You may need to do: 
apt-get install libgtk2.0-common
http://forums.mozillazine.org/viewtopic.php?f=6&t=113419

Also, edit your Ubuntu bash profile
http://ubuntuforums.org/showthread.php?t=1707261
vim ~/.bashrc

Add your GTK library to LD_LIBRARY_PATH 
http://www.mathematik.uni-ulm.de/help/gtk+-1.1.3/gtkfaq-2.html

ALso, try installing with as this worked for me:
apt-get install libgtk2.0-dev

Install java 8
sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
http://tecadmin.net/install-oracle-java-8-jdk-8-ubuntu-via-ppa/#

I had serious issues with configuring Netbeans and Eclipse IDEs for wxWidgets, but it 
seems CodeLite IDE has preconfigured settings for wxWidgets. 

http://askubuntu.com/questions/330268/how-to-install-codelite-on-ubuntu

sudo apt-key adv --fetch-keys http://repos.codelite.org/CodeLite.asc
sudo apt-add-repository "deb http://repos.codelite.org/ubuntu/ $(lsb_release -sc) universe"
sudo apt-get update
sudo apt-get install codelite wxcrafter

Wisest tips for Python 2 vs 3 with Anaconda vs PyCharm

Wisest tips for Python 2 vs 3 with Anaconda vs PyCharm

This came in from a wise software developer with much experience in these environments. Confusing for many I know based on an email I sent out below. Also, check out the 1 on 1 tutorial below to see how I tried to help others. BIG THANKS to this person for helping who is among some really amazing generous people in this community!

 

I sense your frustration with the mixed python environments when trying to get everything to play nicely (from your video) . May I suggest that you try setting up virtual python environments with “vritualenv”  (and/or manage multiple environments with “virtualenvwrapper”). Create your virtual environment and install Anaconda for python 2.7  into one of the virtual environments that you have setup and that way you have a isolated sandbox with which you can only use that version of python (the other installs are invisible to this environment unless you choose to make them visible – that is a switch in the virtualenv setup), IDE (Spyder) etc Anaconda only, and pip Mongodb will install in this Anaconda environment- without leaking into your other environments. You can setup another for Anaconda for python 3, another for Pycharm etc….

 

By the way “pip” does work with Anaconda for packages that are not part of Anaconda, you just have to manage those packages yourself and I have never had any issues.

Here are some resources that may be useful to explore should you wish to go down that path.
