I'm not a customer of InteractiveBrokers. I wrote some questions to
them regarding their service. I thought people on this list might
be interested in the answers.
Q: Do any of the data subscriptions include market breadth? By
this I mean number of advancing, declining, and unchanged issues
on the NASDAQ or NYSE, and the volume of advancing, declining and
unchanged issues. I could not find ticker symbols for any of those
things. Would I need a 3rd-party data feed for this?
A: This is not available through IB.
Q: If you do not have this market breadth data available, I would
need to write custom software to obtain quotes through the TWS API
for hundreds of issues. I don't want to overload anything. Is it
possible to request so much that the data feed gets saturated? If
so, what are the limits?
A: 40 tickers is the limit.
Q: Does the data received by TWS consist of tick data, or rather
does it consist of data updated every minute?
A: Data is sent in .7 second snapshots.
Q: If I write custom software to use the TWS API, can my account
be set up to accept "fake orders" while I ensure that my software
works properly? Moreover, if I place a fake order with TWS, is it
possible to get a "fake confirmation" returned from your server?
A: Yes, the Demo system allows you to develop against a demo account
(but will work with a production account later).
Q: Your web site has a separate "equities demo" and "commodities
demo." However, I notice that I can have an account that lets me
trade both equities and commodities. Do I need to run two different
versions of TWS to trade those different types of instruments?
A: For the demo, yes, for a universal account, no.
