Theta decay slower on some days than others on 0dte, its like the market “knows” something? 🤔

And no I’m not talking about fed days or big news days. Some days I’ll open a 0dte iron condor and get my 50% profit within an hour, but other days despite paying similar premium for the same width, the decay just isn’t happening and stays stuck only for a big move later to wipe me out?

It’s almost like the market God or “someone” knows something that I don’t and hence greatly slows down the theta decay some days and before you know it, that big move does happen and I’m wiped. Why is this?
