Quote from syswizard:
Keep in mind, all of this is moot if you are only tracking/trading 1 or 2 symbols. This rec is more geared to those traders handling 20-100 symbols with multiple indicators / systems running.
Perfect summation. Kudos.
If I might add, having several trading computers also makes sense if one is tracking more than 20 symbols. While you can have multiple monitor setups, you want as much processing power devoted optimally to a handful of symbols and their associated analysis.
