No dont sell on the way up. That is what to HFs want us to do as it will take momentum out of the MOASS (limiting the peak by giving the HFs shares to buy and cover their position).

You will see every price twice. Once on the way up, and then again on the way down.

Absolutely no reason to sell for a smaller price on the way up, when you could just wait a day or two and sell for that same low price on the way down. Of course by that time you will actually know what the peak is and will slap yourself for almost selling for peanuts on the way up.

SELL AFTER THE PEAK ON THE WAY DOWN.
