Ken, Try one tick instead of 400 for your chart settings.
I am going through the same problem today, trying to set up a 400 tick AB chart, but from the DTN IQFeed tick data (I also have TOS). The TOS is sending one 400 tick candle, not 400 separate ticks. The IQFeed + AB tick database does not seem to have a concept of anything other than single ticks AFAIK. This of course poses a problem for me to backtest 3 years of ES futures data on a 400 tick chart. I would need about half a billion ticks in the database. That is not practical at all. with 400 tick bars in the database, it would be a more manageable number like 1-2 million. AB can convert a tick database to anything, but a liquid product like ES needs over 500,000 ticks to cover one 24 hour period. I think that one of the settings should be able to display the 400 tick candle as a single unit.
