Drawn by your post from 2010, I'm looking for info on market making in SPX and SPXW options for an academic paper on index option mispricing (if you are interested I may elaborate what we mean by that, with possible implications for non-academic profits)
Thanks. I use TD Ameritrade. I had a worthless option in NKLA go to $4 per share intrinsic value after hours and submitted exercise order a at 5:08pm. I am waiting to see if it exercised. I like being able to submit exercise order online instead of over phone like other brokerages.
Hi. Which Brokerage do you use? I have been trying to find the brokerage with the best after hours option exercise abilities.
My main broker is Dash Prime. Their cutoff time is 515pm et, with best efforts after that. You can do the exercise online as well.
