Just a final thank-you for the help I received on the list
It works just GREAT. If you have a LAN and haven't tried this setup you
should...
best regards,
herman

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
Host Name . . . . . . . . . . . . : Rocket
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown
IP Routing Enabled. . . . . . . . : No
WINS Proxy Enabled. . . . . . . . : No
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :

Controller
Physical Address. . . . . . . . . : 00-15-58-04-A0-8D
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.1.9
Subnet Mask . . . . . . . . . . . : 255.255.255.0
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.

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
