there was a big IBTWS update last night. There has always been something screwy with volume from IBAPI. The attached chart shows a tick chart of SPY during cash hours for the past week or so. the purple boxes are backfilled historical data when i was not connected to sierra or TWS. Note that the times i am connected, the volumes are 10-20x larger, as you describe. No idea why, but its been that way for a while
