I am looking at the 1DTE QQQ options chain. When i scroll down to puts at 570 strike, they only cost .01 each. But the crazy thing is the open interest. everything under 575 is in the THOUSANDS. Who is buying all these wayyyy otm 1DTE puts? What is the point of doing this? I understand institutional hedging against a possible downturn, but 1DTE??? Do they do this everyday?
