Does today not perfectly represent the new normal with 0DTE? Very small gap at the open with QQQ and they immediately buy the dip. Then it just chops around in a narrow range and every time it threatens to lose the range, it's saved with a V. This market will never make another meaningful down swing ever again. You might get a random red day, but the next day it will V.
If what you say is true you should have a very profitable trading method at your hands.
Now, on a more serious note, it would be interesting to know how the rise of 0DTE have impacted index futures. I haven't noticed anything special myself. There's "always" been a bid in this market as far as I can observe. The strong trend day down without any significant retraces is quite rare.
