How to know when is the best moment to sell?

[joypark333]

Few weeks ago I bought some HempCoins at 0.126$.
A few days later the price went up to 0.2$, it was the ATH. I thought it was just a common pump and dump. I predicted the price would go down after the pump, so I sold them.
Unfortunately, the price 0.2$ was just the beginning of the pump, after I sold them, the price rose to 0.52$.  Now the price (0.34$) is stabilized. I wish I could sell them for a higher price.
So, here is the question, How to know when is the best moment to sell? We all want to sell at the ATH and buy the dip. Thank you for answering.

This is not a so easy question, especially if you are holding for medium/long term.

I suggest you to define a strategy and stick to it  for a little while before changing your own rules (if needed)



You can delimit things with 2 questions :

1/ at what profit do you want to sell a fraction of what you hold?
+20%?
+70%?

2/ how much do you want to sell once the profit target is reached?
25% of the total?
selling half on the double?


Today my strategy is to sell a fraction even if i know the price will go higher.

For little gambles i sell 33% or 50% at double, then hold the rest until the price is fine.

For more serious investments i sell like 10% at different stages, it helps me holding better the rest, and by taking a bit of profit earlier i am less "stressed" by the evolution of price.
