Quote from Tums:
you can open up to 3 accounts on each computer.
each account can only opened once at a time.
if you need datafeed, open the papertrade account on the 2nd computer.
Quote from NoWorries:
maybe open a paper trading account and use that for the charts?

Quote from dchang0:
Wait, isn't the demo user account delayed by 15 or 20 minutes? Wouldn't do much good for intraday trading.
I assume then that by "paper trading account," you mean one that is funded but that you won't trade live with. But then, why not just sign up with a real data provider and get the additonal features of backfills, etc.?
