I am using IB as data provider. When I pulled out a 1000 tick chart of ES 09-2010 of yesterday (6/16/10), there were only 20 bars from 9:30 to 4:00 ET. I suspect it is not quite right. Is it possible that IB doesn't provide tick by tick data so that the tick chart is not reliable. The data provider matrix page indicates that IB doesn't not support historical tick data. Does it also mean it does not provide reliable real-time tick data so the tick chart may look fishy?
Thx.
