Going to be a mess for some time with lots of weird strikes.
So the illiquidity will come from people preferring round numbers then...
I did read somewhere that you wouldn't be able to open new positions on such calls, but I don't know whether that's accurate or not.
In any case, to avoid any doubt, I adapted the couple I had to nice post-splitterino strikes.
TBH, will be happy when we get to next Monday and all this nonsense is over, plus the SP can power through $500 on the opening day![]()
They could just round the strikes, and give back the balance as credit/debit to your account. I don't think they can handle all the fractions that will occur.
