Is anyone actually making money using Think or Swim?

But so does IBKR. I trade with both and IBKR fill quality is better (can go into detail privately) but no what if. No beta-delts (d-dollars) outside of RiskNav.

 

You can't be serious. You just can't.

 

I do all the what if, etc in excel. I only use Etrade calcs to sanity check in case I have a zero IV or something.

 

how did we get off on market making? tos is not market making software. it's for placing orders professional or not depends on how big your boat is to steer.

 

Sure you did. All hat, no cowboy.

 

I ran the ISE/BOX MM desk for a bulge bracket bank in the early 2000s.

 

Well then you should prob go with IBKR for the SPX overnight access. Fills are really remarkably tight.

 

im contemplating it. I can explain why privately.

 

Hit me up in the room.

 

So, to sum it up, you aren't making a living using TOS?
