And for selling I would say until I reach my targeted price/profit. If the target is not reached, I make a small profit but at many different price points. That helps me minimize my losses.
That's a good strategy that can be shared with everybody. When our targeted price is quite high and it's unlikely to be reached, we can DCA at the opposite timing.
While we're DCAing as we buy, this can also be done in selling. You sell at many intervals and prices just for you to have that point of selling based on what satisfies you.
When the price is not good enough then you don't have to sell as no one forces you. But this is a market that we need to take advantage whenever we're in profit.
