I try to write my own datafeeder for Metatrader 5 using Gateway API. I compiled Gateway API examples, but when I try to run them, my Metatrader test server says: "datafeeder status - offline". It just couldn't see my datafeeder. Does anybody have any ideas or samples how to connect datafeeders to server?
I fixed it. I just had to move datafeed.exe to Metatrader Server Datafeed folder.

I have a Server App created with Nodejs using "ejs" view engine.
When I start the Server and is running on the port, I click the URL and it sends me to my APP with no problem.
When I try to do it with Live server is when I am facing issues.
In Live Server instructions says: [NOTE: In case if you don't have any .html or .htm file in your workspace then you have to follow method no 4 & 5 to start server.]
That is what I do and I get redirected to, please see image below:
Could any one help me with this issue, please ?
Thanks
You can see it here

like this.
Just write to your server.js "localhost:(your-port)"
and you are ready to go

I`m totally new to Bloomberg and using Bloomberg api in python/flask
I tried to read all the documentation provided by the windows SDK
I understand that DAPI is only for local applications using localhost and default port
but actually I am confused about the usage of SAPI Installation and usage...
First:
after installing sapi on machine with bloomberg terminal and letting the sapi process up , I will write an application by python code that import blbapi and use the sapi
should this application be on the same machine , or it can be on another machine and give it the ip and port of the sapi process and should the other machine have bloomberg terminal too?
second:
what about the client side, any browser which open this application should the clients have bloomberg terminal too??
Excuse my naive question ..
Thanx in advance
Python application machine doesn't have to have a Bloomberg terminal installed. You will only need Bloomberg libraries installed (but not terminal) software.
You need to provide "ip of terminal pc" + "uuid" when making a connection to SAPI.
Also, the user/terminal must be logged in.
Check and be very careful with licensing. You can try asking your account manager.
Don't take this as licensing advice, but different exchanges and data sources can have different rules around the data so it depends what data you pulling. As I understand the data pulled by a user/script is for that specific terminal owner only.
Different terminal "owners" with the same access might not be allowed to see the data pulled by other scripts/users.
SAPI allows you to use BBG data off the machine where the user is logged in HOWEVER this data can not be viewed by anyone but the logged in user - for legal reasons rather than technical ones.
The typical use case for SAPI is there complicated calculatios (be it exotic pricing or realtime portfolio risk) is being performed that aren't practical on the desktop.
Be aware that all BBG data and calculations are tied to the user, the data can't be given to anyone else...
I already have a ZooKeeper cluster up and running, but I want to interface with it through PHP code? I've seen the ZooKeeper php extension on GitHub (https://github.com/andreiz/php-zookeeper) but I'm new to PHP/ZK and I'm not sure how to get started with connecting to ZK using PHP.
I have used the same PHP client and did not have any problem. It is a pretty good API. I followed the steps from here to get started:
http://systemsarchitect.net/distributed-application-in-php-with-apache-zookeeper/
And then you can also view the example code on GitHub.
I am not a developer so please keep that in mind when reading the following message:
I need to be able to use Windows PowerShell to connect to a JMX RMI agent on a host, is this even possible ?
The example string from the java client I have been given is as below:
JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:7979/jmxrmi");
The reason for this is that I am doing other work in my PowerShell script and would like to keep it all in one place.
Thanks !
This is an unusual mix of two technologies, but it is possible.
On the off-chance that you are attempting to connect to a JBoss server, the quickest way may be for you to call twiddle, a command tool that will dispatch JMX requests to the target JBoss server and return the results to standard out.
Another way is to implement the Jolokia agent on the target servers. This will allow you to issue JMX requests using REST. Responses will also be returned in REST format which you can process in PowerShell using one of these solutions.
Thirdly, you can also deploy the JMX-WS service on your target servers which will allow you to communicate with the JMX server using web-services. This document provides some VBScript examples of this.
None of the above actually uses the JMXServiceURL syntax you outlined, and I cannot think of a way you could actually cleanly integrate this RMI based protocol into PowerShell, but hopefully one of the above will work for you.
========== UPDATE ==========
There may be a way to use the RMI implementation. Take a look at IKVM. It is a Java Byte Code to .NET compiler. I have successfully compiled JMX/RMI java code into a .Net assembly and used it from C#. I think PowerShell will do the same thing.
