OK, I have had the opportunity to do some testing and it appears that
Ibrokers will only pick up reqMktData (at least on ASX stocks) when they
are also being monitored in the TWS. I had already established that
transaction ids are difficult to come by unless you commence a new
process (at least in windows) so the take home from that, until I or
someone else has the time to look into it, is that you should always
start a new command prompt to run R at if you want to deal and also you
should have any stocks you want to get the prices of into R being
monitored in the TWS on your computer. Hope that helps anyone trying to
set up on a windows machine maybe its the same on other os's.

Stephen,
You're asking others to do an awful lot of work for you for free and
in their spare time. You're asking others to help debug ~800 lines of
your code (not just R, but Perl as well!). I would be surprised if
anyone helps you with this (unless the issue is obvious to them).
I don't say this to chide, but to help you ask questions that are more
likely to be answered. Someone will be much more likely to help you
if you create a minimal example (without Perl) that replicates this
issue with your callback code.
Best,

Hi
I am running on windows using an IB workstation with R talking to it.
It all seems to work, but I find that when running my own callback (code
attached):
1. I have to make sure I start a clean (new) command windows or
something goes wrong with the allocation of a transaction id via
reqIds (Ok I just work around by opening a new command prompt and
2. (big problem) I don't always get the prices back so the algorithms
don't always work. For example this is the output of that code:
[1] "Existing Position: JBH " "18.51"
[3] "MYR " "3.65"
[5] "Spread " "14.86"
2 -1 2103 Market data farm connection is broken:aufarm
[1] "I HAVE TRADED AT AVERAGE CLOSING SHORT. SELL"
[2] "52"
[3] "JBH. BUY"
[4] "280"
[5] "MYR"
[1] "Time" "2011-01-31 15:34:02.373"
[1] "LEI " NA
[3] "WOR " NA
[5] "Spread " NA
[7] "The boundaries are 4.46697721920205" "lower 2.44602278079795"
[9] " mean is 3.4565"
[1] "QBE " NA
[3] "AMP " NA
[5] "Spread " NA
[7] "The boundaries are 13.3779288310757" "lower 12.2030711689243"
[9] " mean is 12.7905"
[1] "QBE " NA
[3] "AXA " NA
[5] "Spread " NA
[7] "The boundaries are 12.1631661762672" "lower 11.1048338237328"
[9] " mean is 11.634"
I'm getting the prices for JBH and MYR but not for the other stocks. The
boundary/mean figures are hard coded in my function but were obtained in a
previous IB call but that was a different call reqHistoricalData where as
this is reqMktData. My perl code to manage that part of the exercise is
attached.
One thing I have noticed is that if I get my trader work station to show the
price and stop and restart my trading.R code I do get a price. Does anyone
else have experience of reqMktData not showing prices if they are not live
on the TWS?
