I observed this during the week of May 4 of this year. I like to do CSPs and sell at the mark, but after this date, I am no longer able to sell at the mark (TQQQ, SPY, PLTR, any ticker that came to mind wouldn’t trigger). I used to be able to sell at the mark no issue. I assume all of the volatility with the current state of the world creates uncertainty, and the market makers are more risk averse and not taking these trades, effectively forcing me to sell closer to the Ask if I want the trade to go through. Has anyone else observed something similar in the past month?
