I am completely encouraged to see you using Think or Swim. I have become comfortable with this platform but often feel that as a new challenge student I'm out of the loop with the others as nobody talks positively about TD Ameritrade as a whole. Do you use it for regular trading or just for analysis reviews? I've also heard you speak of DOS & STT, do believe one has better execution then another and if so do you feel it is enough to justify additional expense. Thanks you for the fantastic reviews and chart analysis.
