I have been attaching QS to a real Interactive Brokers account for the past few weeks. That has been a favorable experience:
- A number of charts at various frequencies all update properly.
- IB (TWS) disconnected temporarily (~2 min) a few days ago. QS resumed automatically when the connection was restored --- i.e., did not require
manual intervention, which is nice to know for sporadically attended situations. I could not tell whether QS did or did not refill on reconnection.
- On start up there is a backfill as each chart is first viewed, which seems to mean the bars are refreshed from 'scrubbed' data. That is (would be) a
good thing.
- You can disconnect a live feed at the end of the day and reestablish it the next morning. However, if you don't disconnect and just close the
application the live feed is automatically resumed the next time you start QS. Nice. (In my case TWS is on another machine on a LAN to which
QS attaches just fine.)

So far my only difficulty was my setting up a parameter wrong which QS support fixed for me.

If you are considering real time my experience should encourage to go ahead and try it.

Thanks a lot Peter for sharing your experience.

In "Connection Settings -> Backfill Settings", you can specify whether to backfill after a disconnection or not.

Anyone had a successful "Backfill when system detects a disconnect" using IB? I had an instance where ISP was down, and when it reconnected it streamed all my symbols OK, but it did not go back and get my missing data via auto backfill.

The ATS log shows the system detected a disconnect. This obviously can be an issue if my ATS "missed" something.

Just curious if anyone else has had any experience here.

Did you enable the auto backfill feature in "Connection Settings -> Backfill Settings"?

Yes, That is why I am asking if anyone has had any success with it. It did not behave as I anticipated.

This is because currently, auto-backfill is enabled only if there are less than 20 streaming securities. We will increase this value in future releases.

Thanks. It would be nice if it equaled the MAX # symbols to stream setting. Also, Had a few more questions in a new thread.

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
