If you are happy to sell at these times with the current price, you're free to do it and just buy back when it dips.
So you pull out a bit of profit from that sale and then you keep it while leaving the amount that you'll use again for buying back. With that manner, you'll still not gonna be left behind.
Actually everyone is entitled to choose whatever method that's well suitable for them, but responding based on our discussion and strategies here we don't advise buying low and selling higher if the price retrace up, is actually a gambling strategy were as the possibility of making a profits or losing money is on a 50 to 50 percent chances, perhaps you could be left behind while selling off your investment were as the market will keep shooting up and never give you the chance to buy back again, so perhaps I will just suggest you hold for long instead of chasing the market price.
