The AB web site says: "The finest resolution of BACKFILLS that Interactive Brokers TWS offers is 1-SECOND bars. It means that although you can collect streaming real-time data in tick format, the backfill will always have resolution limited to 1-second bars. Also IB TWS streaming data are NOT tick-by-tick, but rather 0.2-0.3 second snapshots.
For this reason we recommend using higher intervals like 5-sec, 15-sec or
better yet 1 minute."
Does this means one can't use tick charts with IB data?
