Hi all.

if I use reqMktData(), it gives me a continuous feed of market data of
a SINGLE stock/future and then I can write callback functions to
handle the incoming data.

For the task at hand, I need a feed of at least two (preferably 40)
different assets/derivatives. At each iteration, I would like to pick
up the market data for about 40 stocks/futures. Currently, there
doesn't seem to be anything in IBrokers that could help me with this
(please correct me if I am wrong). twsBag seemed it could fit the
bill, but I can't figure out given the extreme lack of documentation.

It would be possible to have two different feeds getting the data
using to different connections (client ids) and use a third routine to
look at them and do some kind of pseudo-synchronisation and take the
trading decisions, but that would be an ugly solution.

Any ideas?

Thanks in advance,

Soumendra

Hi Soumendra,

You can specify more than one contract by simply creating a list of
twsContracts.  This is mentioned in a few places (slides, videos), but
the ?reqMktData doesn't really give a good example of how.  See below
for an example, but I'll update the docs to be more clear.  This
approach works for RealTimeBars as well.

Note that the API restricts the number of symbols you can display (via
API and TWS) to 100 typically, though that number can increase
depending on your trading/account/fees.
No, twsBag is for combo orders.  Not the same.
Best,
Jeff

tws <- twsConnect()
cons <- lapply(c("AAPL","MSFT","GOOG"), twsSTK)  # create a list of
twsEquity contracts
