Gary,
 
If you filter out premarket data, the indicators 
will be built with market hour data only. The pre-market data just does not 
exist for calculations after it's been filtered out

  Ara,
   
  I'd test this myself if I was getting pre-market data.  Are you 
  saying that if I'm bringing in pre-market data, but am filtering it out the 
  chart will only display regular trading hours but indicators will be 
  calculated on ALL data (i.e. pre and regular trading hours)?
   
  Thanks,
