Just a nonsense.....!
I try to be open-minded. If something I wrote is nonsense, I would like to know why is it nonsense.
When I observe the market, I try to make it an objective exercise using indicators that are objective and easy to interpret. Moving averages fit the bill.
Moving averages look only at the past and do not look forward. This is objective.
With one look, one can see whether the price is above or below the moving average. This is easy to interpret.
As to what moving average to choose, it is more subjective. An example of why some moving averages are significant when violated. S&P500 rebounded off 50-day moving average 7 times this year. In this context, 50-day would be a good choice for S&P500 because if this defence line is violated next time, that is a notable bearish event.
