IB data is completely useless. Like mentioned
here during market hours it is almost impossible to get data. So if you plan
to add a symbol during market hours forget about it.
I experienced that my internet connection went
offline and when it returned to the online status I could not backfill the
data for that day even though it said that the data had been backfilled. So
the data for POT for that day where gone and I could not backfill them during
market hours. Luckily I also use IQFeed but I used to use IB data to execute
the systems. Seems the quality is getting worse each day.

Subject: [amibroker] Slow IB
backfills
Anyone having problems with IB backfills on futures. I am requesting a 5
day backfill and it is excruciatingly slow.
