historical data: "contract ambiguous, specify currency"

[mc]

I tried to download AAPL (and EBAY) tickers from TWS under "historical
data", but every request returns with status "Error: The contract
description specified for AAPL is ambiguous; you must specify the
currency". Any ideas how to do that, or set preferences in TWS/IbPy?

I am using profitpy-svn, IbPy-svn, TWS demo 889.4 on Ubuntu 8.10

cheers,

Hm. Something in the TWS API has changed. I get this error, too.

When I hard coded the contract currency, I no longer got the error,
but the histdata requests still did not complete.

Could you svn up and try your requests with r332?

Yup, that's better, thanks! Works for me for pulling e.g. AAPL 2 days,
1 min bars, "beginning" 2009/1/7 8AM. It retrieves the data up to that
point in time, not beginning as labeled, but I can adjust to that ;-)

Next problem I ran into was trying to retrieve ES/ESH9 future data,
returns: "-'wb' : cause - Please enter a local symbol or an expiry" Is
this suppposed to work? I found some documentation on IB naming but
how would I enter this in the dialog?

Furthermore, how does "historical data" relate to "tickers", my list
of tickers is still empty despite the "finished" data request for
AAPL? I am stuck on what to do next.

Sorry for being a pain in the neck. I would love to contribute, but
this is really hard to figure out without any instructions. A simple
step-by-step walkthrough "click on this", "enter that" would help
tremendously with getting up to speed. I volunteer to document my
learning curve later on.

Thanks again,
