And how are people going to know that unless they have insider information?? And if they are trading index options, they won't even know that. And on those days that they encounter those "bandits in ski masks", they lose 10% of their trading capital and you think it's ok for a retail trader?
And using your analogy, the problem is during the days when it's you that's encountering the "bunch of guys with ski masks", you lose everything that you have earned in your bank account because the "bunch of guys with ski masks" force you to withdraw them all from the ATM. But then when you decide to don a ski mask to stand by the ATM machines, the bank tells you you can rob the ATM machines when the bank is closed and the doors to the ATM machines are locked.
I am sure your pea little brain didn't understand my analogy. But anyway don't give a shit. For people who are genuinely concerned about retail traders' welfare, they will know what I am talking about. Really done with you here.
That's the hard part of trading options. Figuring out when there will be a vol event. If you can't do that, then you are just churning dollars.
This is true of everything. You have to know which battles are in your favor.
