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
