Hi Herman
127.0.0.1 is the internal address for the computer you are on. So the default for the IB plugin is to connect to this 127.0.0.1 address because you usually have both AB and TWS on the same machine. It means 'connect to myself' .
You want to configure the IB plugin to connect to another machine.
To do this, you need to find the IP addreses of both computers and configure the AB/IB plugin and TWS appropriately.
Sounds complicated, but it's quite simple really.
Find it's IP address of the computer running TWS ...(let's call it TWS-Computer for this example)
by doing the following.
1) open a cmd prompt (start /AllPrograms/Accessories/cmd prompt
2) In that cmd prompt type 'ipconfig /all'. This will display the machines real IP address (see display below)
3) Write this address down. (for this example, let's say it's IP is 192.168.0.100 )
Find the address of the computer running running AB, .. (lets call it AB-Computer)
1) Find it's IP address the same way as above. .,. and write it down. .. Lets say it's 192.168.0.101
2) In Amibroker, go to Menu FILE/Database Settings
3) On the Database Settings dialog, click Configure to display the IB Plug-in settings
4) Here's you will see a line that says 'TWS Host or IP'. It will be defaulting to 127.0.0.1
5) Change this to the IP address of Computer1 (the one running TWS)
6) Leave the other stuff alone.
7) This tells AB to go use the TWS on the other computer
TWS on the first computer may display the 'Accept incoming connection' dialog. Just answer 'OK'
You can prevent this dialog by configuring TWS to trust the IP address of the AB-Computer.
You do this in TWS using the Configure/API/Trusted IP address menu. Just add a new entry with the address of your AB-computer. (192.168.0.101 from our example above)
Here's an example of the 'ipconfig /all' command. You're looking for the IP Address field
C:\>ipconfig /all
Windows IP Configuration

Primary Dns Suffix . . . . . . . :

Default Gateway . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 192.168.1.1
C:\>
One last thing .. if your using a home router, such as a Linksys, DLink, Belkin etc, then there's a good chance that these IP addresses may change from time to time. This is because the router dynamically assigns you a new address when needed.
They don't change often if the machines are used frequently, but it is something to consider if this stops working one day.
I can help you nail down the IP address so it doesn't change if you want, but it should be necessary right away.

Subject: RE: [amibroker] LAN Computers + IB RT-Data
OK, I
got my computers running again. AB. I have the TWS
running on one and the TWS on the other... Problem is that my AB IB plugin
status stays Red.
Seems
like this is working for you, I may need a bit more basic instructions. .. could
you tell me what else i have to do?
If i
understand you correctly you collect data on one computer from a
TWS running on the other - is this correct?
What
if both my computer use the IP 127.0.0.1 ? should i change one? How do i do
that?
many
thanks for you help...

You can connect to a TWS on another
computer.
File\Database\ DatabaseSettings ... Configure .. and put the IP
address of the computer running TWS. Usually is 127.0.0.1 which is the
local computer.
Not sure if this is what you want to do though, but it
might be a work-around.

Hello,
I am using IB real time data and have
three computers on my LAN. Typically I trade one or two
computers and do developement on my laptop. I use my Real Account,
Simulated account, and the eDemo account. This way of becoming RT funtional
on each computer is not optimum and I would much
prefer to have access to the same
IB data on each of my computers. I assume many users use a LAN and have
the same problem...
Technically data-sharing over the
LAN should be very easy to implement since IB data dribbles in at about
two quotes per second, plenty slow for my main computer to publish data
on my LAN and to be used by my other computers with virtually
no degradation.
Has Anyone done this?
Thanks and best regards,
herman
