Hi. Sorry for the late reply. I'm still not used to this new format, so I don't notice messages in the inbox. I have both the StreetsmartEdge and Think or Swim Desktop (separate installed programs) on my computer.
I can use them both currently, (I've had them for a long time). Yes, the ThinkorSwim has lots of bells and whistles. I really don't do much daytrading/flipping, (and when I do I suck lol), so I don't need any of what ThinkorSwim offers. I will log in to see what stocks are tanking premarket (See photo). In one of the side-window "widgets", Or I can follow what stocks are tanking real-time during regular hours.
I don't trade in TD Ameritrade at all, I have a few accounts with them, but no money to speak of. When I do trade (Schwab, Fidelity and others) I just use their web-based trading.
I think that's really dumb that you can't use both ThinkorSwim and StreetSmartEdge simultaneously, so you can have smooth transition
