One thing you are missing is that this is not a high volatility top like 2000.... It is likely that this top will come on lower P/C ratio. In fact it is likely that that peak of 1.75 in late September was the top for this OEX P/C cycle.
As you may have noticed, 10 DMA of OEX P/C hit 2+ at the beginning of 2000 which was 2 months early.
So that September reading of 1.75 could very well be THE top and this first lower impulse OEX P/C currently forming may trigger the first trust of this coming bear market.
It is generally a matters of days not weeks when the 10 DMA is high on OEX P/C. The question really is do you trade on this signal alone.... Regardless it is a bearish signal when the 10 DMA is over 1.60 until it goes under 1.40. You should not be long during this time. At 1.40 it goes back to Neutral. I'm doubling down going 2X short on this signal
