Metastock Real Time

["Zak Maymin" <maymin@xxxxxxxxxxxxx>]

If somebody is (was) using Metastock 6.5, I have a few questions.
1. Is it possible to use real time data in Metastock? 
2. Is it possible to call Excel, for real time data as we do in 
TradeStation?
3. In general, what are the major differences between
   Metastock and TradeStation?

Thanks in advance,
    -Zak.
