I don't have to. MAs don't work, and you are not some 1:10,000,000 person who has figured out how to make them work.
I will agree that MAs do not work as a predictive indicator in their own right, stand alone. They are the very definition of lagging indicators, which all indicators are. But combined with trader knowledge and a few other indicating bits, absent any news, they can help show what most markets are likely to do "most of the time".
In that vein, they have predictive power on the probability of their next move, based on the previous moves. But with that Angry Orange in office, I would not attempt it.
Hell, we are nearing cycle number 3 of the trade/Fed thing. Cycle 1 started on May 5th. Cycle 2 started on Aug 1st. Cycle 3, barring any shit fits from this shit face in the oval office, is going to be next Wed, the Fed rate decision. It will be very very sad if we get near the ATH next week, and then Trump twits some falderal about how unhappy he is with Powell, and we drop 5% from there. It is not that it is untradeable, it is just that it is getting so old. It almost all seems illegal. Is he really manipulating the economy for his own gain? The SEC should be investigating this by now.
The IRS nailed Al Capone on tax-evasion way-back-when. Time to put Orangeface under that same microscope.
