If you still have difficulties launching ProRealTime after re-installing Java on Mac OS X, please check the next question.
What should I do if I have re-installed java and the platform still won't launch?
If you still can't launch the workstation after having re-installed java as described in the previous section, we advise you to check each of the following points:
Configuration of your security software (antivirus / firewall / anti-spyware)
Different security softwares protect your computer. The firewalls integrated in these software programs may prevent ProRealTime from launching, as described below :
Firewalls in your antivirus or security suite
Most recent antivirus programs include Internet/Network protection services (firewalls).
Make sure that the firewall integrated in your antivirus software authorizes Java to freely access the Internet. If you have difficulties configuring your antivirus software, contact the customer service of the software provider for help.
Even if you have already successfully configured your antivirus in the past, note that an automatic software update (of your operating system, of your antivirus software or of Java) may make it necessary to reconfigure it.
Firewall of your operating system
Check that Java is in the list of programs authorized by your firewall. If you have difficulty configuring your firewall, click here for more information.
Additional firewalls
More rarely, an additional firewall may be integrated to your internet router. If this is the case, contact your internet access provider for help configuring it.
Finally, check that there are not multiple firewall and antivirus programs installed simultaneously on your computer. The presence of multiple antivirus programs and firewalls may create conflicts.
"Java..." image appears but nothing happens afterwards
This situation arises when Java closes unexpectedly prior to launch. This can happen when you allocate 4 GB (or more) to ProRealTilme thanks to the memory selector while using Java 32-bit.
Note : if the memory selector is not displayed on your home page once logged in, simply click on the "Modify" link on the lower right part of the launching frame.
If you want to launch ProRealTime with more than 4 GB memory allocated, you must :
- Have a 64-bit operating system
- Have Java 64-bit installed on your machine. See how to install Java 64-bit.
If you have activated "Custom memory mode", advices given above remain the same. You can otherwise use the dropdown menu to choose a lower % of memory to allocate to ProRealTime or click the link to return to "Standard mode".
"Could not create Java virtual machine" error
Please refer to the ""Java..." image appears but nothing happens afterwards" question just above : the source of this issue is identical.

The file "StartProRealtime.jnlp" doesn't launch with Java
By default .jnlp files used to launch ProRealTime are opened with the Java program (javaws.exe). This file association may not be correctly configured on your computer (for example, if the file is opened by a program other than Java). Reinstalling java will usually fix this problem automatically.
If not, try using another web browser and launching the platform again. If even changing the web browser does not fix the problem, click here.
Use of a proxy or connection via a public network
If you are connecting to the Internet via a proxy, a company network, a private network (university, school, administrative building, library), or a public network (ex: Wi-Fi hotspot), contact the administrator of that network for help configuring access to ProRealTime.
These networks are sometimes set up to limit access to external sites. The points discussed above will help your network administrator to setup an appropriate configuration.

How to re-establish the association of ".jnlp" files with Java
The association of ".jnlp" files with Java may not be correctly configured on your computer in some cases (ex: if the file opens with a program other than Java). The following procedure lets you re-establish this association.
With Google Chrome or Internet Explorer on Windows
This is a process to re-establish file associations globally because those web-browsers use Windows parameters to launch .jnlp files:
- Open the file "Downloads" (or the default download folder you set up in your web browser if different)
- Locate the file "StartProRealTime.jnlp" and right-click on it
- Select "Open with" and select "Choose default program..."
- In the window that opens, choose "Browse"
- Go to the Java directory (usually "C:/Programs/Java/jre1.8.x_xx/bin") and choose to open "javaws.exe" (where "x_xx" is the Java version number)
- Click OK
With Firefox on Windows or Mac OS X
From the Firefox web browser:
- Go to the "Tools" menu and click "Options" > Go to the "Applications" tab > Enter "JNLP" in the search bar
- If you don't see the "Tools" menu, go to the menu "Firefox" > "Options" > check "Menu Bar" to make the "Tools" menu appear, then continue with these instructions
- Once the line "JNLP file" has been found click on "Other..." > Click "Browse..."
- Go to the Java directory (usually "C:/Programs/Java/jre1.8.x_xx/bin") and choose to open "javaws.exe" (where "x_xx" is the Java version number)
- Click OK
With Safari or Google Chrome on a Mac
This is a process to re-establish file associations globally because Safari uses Mac OSX parameters to launch ".jnlp" files:
- Open "Finder" then go to the "Downloads" tab (the folder where "StartProRealTime.jnlp" is downloaded)
- Find the file "StartProRealTime.jnlp" and right-click on it
- Select the line "Get info"
- In the window that opens, click the tab "Open with"
- In the dropdown menu, choose "Java WebStart TM"
- Click OK
Launching ProRealTime on mobile devices (smartphones, tablets, netbooks etc.) (Display all)
Can I use the platform from a mobile device (smartphones, tablets, netbooks, etc.)?
ProRealTime on smart phones or tablets
A ProRealTime Mobile version is available for smartphones and tablets at the following address: m.prorealtime.com (to be entered from the web browser of your smart phone / mini-tablet).
Click here to learn more about ProRealTime mobile.
ProRealTime on tablets
The ProRealTime Complete and ProRealTime Premium workstations can normally be launched from tablets which use the full version of Windows 8 and respect the minimum requirements mentioned in the first question of this Technical FAQ.
Important: It is necessary to distinguish tablets that use the full version of Windows 8 and tablets that use Windows RT. Tablets that use Windows RT will not be able to launch ProRealTime Premium and ProRealTime Complete. If you want to acquire a tablet to use ProRealTime, make sure that it uses Windows 8 and not Windows RT.
For other tablets (iOS, Android etc.), since Java can't be launched from these tablets or is not supported in an advanced enough way to launch ProRealTime Complete or ProRealTime Premium, there are two possibilities:
Remotely launch ProRealTime Complete/Premium
Some ProRealTime users also use their platform from a tablet (iOS, Android, etc.) by using remote access to their PC. Softwares such as TeamViewer, LogmeIn or PhonemyPC let you take control of your PC remotely from your tablet (iOS, Android, etc.). You can then start ProRealTime Complete or ProReamTime Premium.
ProRealTime Mobile
You can still use ProRealTime Mobile in any case from your tablet (iOS, Android etc.).
Go to m.prorealtime.com from your tablet's web browser to access it.
Click here to learn more about ProRealTime mobile.
ProRealTime on netbooks
ProRealTime Complete and Premium are usable on most netbooks. Launching the platform is possible if your netbook allows normal installation and use of Java and respects the minimal configuration in the first question of this technical FAQ.

Making ProRealTime faster and more efficient on your PC, MAC & Linux (Display all)
My platform is sometimes slow. What can I do?
You can check the following points to improve the performance of your ProRealTime platform.
Power of your computer
First check that your computer respects the minimum requirements discussed in the first question of this FAQ page. To get the most out of ProRealTime, we recommend you have:
- A relatively powerful and/or recent processor
- A 64-bit last generation operating system (ex: Windows 10 or Mac OS X 10.11)
- 4 GB of RAM memory for the Complete version or 8 GB for the Premium version
Configuration of the RAM memory selector on the ProRealTime launching page
The ProRealTime launching page offers a selector letting you choose the amount of RAM memory available on your computer. If you want to allocate 4 GB or more memory, please make sure you have a 64-bit operating system AND Java 64-bit installed : please refer to the question "How can I optimize ProRealTime with a 64-bit operating system?" for more information.
Activate custom memory mode
If you get memory saturation alerts in the platform even after correctly adapting the memory selector you can activate custom memory mode to allocate more memory to ProRealTime. Click here to learn more about custom memory mode.
Platform configuration
In certain cases (ex: computer with low processing power and/or RAM memory) the simultaneous use of features which require significant resources may cause slowness of the platform.
If you notice slowness, is recommended to limit the accumulation of the following elements to improve the performance of your platform:
- Number of personal ProBuilder indicators displayed: ProBuilder indicators (personal indicators) may consume significant resources, particularly if the code is complex. We recommend that you limit the number of personal indicators displayed and optimize their code to make the calculations faster (consult the programming manuals to learn more about this).
- Amount of historical data displayed in each of your charts: when you don't need to see all the historical data, we recommend that you select a view that displays less historical data. For example, 5 charts displaying all available historical data will consume more resources than 20 charts displaying only 100 units of historical data.
- Amount of objects drawn on your charts: too many objects drawn on charts may slow the platform down. This mainly occurs on computers with low processing power and/or RAM memory.
- Number of "list" type windows: too many "list" type windows open simultaneously may slow down the platform (lists, top movers, news, ProScreeners...). This mainly occurs on computers with low processing power and/or RAM memory.
- Other options: you can also modify the following options to improve your platform's performance:
- "Options" > "Display on charts" > Uncheck "Display cursor details on chart windows"
- "Options" > "Colors..." > Uncheck "3-dimensional cell style", "3D effect on candlesticks & histograms", "Anti-aliasing"
- "Options" > "List settings" > Choose "No flickering"
- "Options" > "Alert and sound configuration" > Uncheck "Highlight new events in these lists"
How can I optimize ProRealTime with a 64-bit operating system?
A 64-bit operating system lets you manage more RAM and improve the performance of certain 64-bit compatible programs.
Note : all recent Mac OS X and Windows operating systems are generally provided in 64-bit.
ProRealTime can be launched in 64-bit and consequently benefit from more memory allocation (4 GB or more on the memory selector).
To do this, you need a 64-bit operating system AND a 64-bit Java installed.
How can I find out if my operating system is 32-bit or 64-bit?
If you are using Windows :
- Windows Vista and Windows 7 : Use the "Start" menu to go to the "Control Panel"
Windows 8 : Right-click on the "Start" menu icon and select "Control Panel" in the items list. - Click "System and Maintenance" (skip this step if your Control Panel is not in "Category" display mode).
- Click "System"
- The type of system is listed in the section "System" after the term "Type of System:".
If you are using a Mac OS X:
- Click here to learn more.
Once you confirmed your operating system is 64-bit, please go on Java download page.
- If you are using a 64-bit version of Windows, choose the "Windows Offline 64-bits" version.
- If you are using a 64-bit Mac OS X, choose the "Mac OS X" version
Windows users only :
Once Java 64-bit is installed, you will have to uninstall your Java 32-bit version
- Windows Vista and Windows 7 : Use the "Start" menu to go to the "Control Panel"
Windows 8 : Right-click on the "Start" menu icon and select "Control Panel" in the items list. - Select "Uninstall a program" in the "Programs" category
- In the programs list, select the "Java" version which does not mention "(64-bit)"
- Uninstall it and reboot your computer
You will then be able to use ProRealTime with 4 GB (or more) memory allocation.
How can I find out the amount of RAM memory on my computer?
If you are using Windows :
- Windows Vista and Windows 7 : Use the "Start" menu to go to the "Control Panel"
Windows 8 : Right-click on the "Start" menu icon and select "Control Panel" in the items list. - Click "System and Maintenance" (skip this step if your Control Panel is not in "Category" display mode)
- Click "System"
- The amount of RAM is listed in the "System" section under "Memory (RAM)"
If you are using a Mac OS X:
- Click on the Apple menu
- Click "About this Mac"
- The amount of RAM will be listed under "Memory"
How can I get the most out of custom memory mode?
"Custom Memory" mode lets you choose precisely the amount of memory you want to allocate to your platform, providing higher usage flexibilty.
How to activate custom memory mode:
- Click this link to activate custom memory mode.
- You have 2 settings to configure:
- The horizontal selector lets you specify the amount of RAM memory on your computer. If you don't know how much memory is on your computer, click here
- The dropdown menu lets you choose the % of the total amount of RAM you want to dedicate to ProRealTime.
Example:
You choose 4 GB and 30%, about 1.2 GB will be allocated to ProRealTime at next launch.
We advise you not to go past the recommended limits described below.
Limits:
The following limits depend on your configuration:
- If your operating system is 32-bit, the most you can allocate is "4 GB" combined to "30%" OR "2 GB" combined to "70%".
- If your operating system is 64-bit, the maximum you can allocate is ">8 GB" combined to "80%". You must have Java 64-bit t benefit from those settings.
Check "How to optimize ProRealTime with a 64-bit operating system" for more information. - If you are not sure about your operating system type, please check the question "How can I find out if my operating system is 32-bit or 64-bit?"
After your changes, if ProRealTime does not launch anymore, it is highly probable the % of memory you chose is too high. Reduce this % or go back to standard memory mode to launch the platform normally.
Which web browsers can I use to launch ProRealTime?
Our platforms are compatible with popular browsers (32-bit and 64-bit), including Firefox / Chrome / Safari / Internet Explorer.
