I would like to give credit to the TradingView user 'jscheurichiv', who suggest me to add the US30Y mortgage rate to this serie of ideas titled "Crash Incoming". As in the previous 3 ideas, it seems to be a relation between the previous big 3 crashes with a strong line of resistance (in red in the chart). Should we assume that the recent 15% correction was that 'big crash'?

The recent turnaround (maybe trend change) of the US30Y mortgage rate may suggest that this crash is not over yet:

Update also the other ideas, thanks, stay well.
