Can anyone please suggest that, how should we trade when Bitcoin or any token is above it's all time high.
At that time we don't have any charts,so we should trade with the help of indicator only.....
Well First is How could you determine that the ATH has been broken ? because the ATH today will be Overcome tomorrow or every minute .
So specifically there is no Real ATH breaking.
But About the right answer in your question ? that will depend on your Amount target because if you have bought in lower Value before that crossing then what hinders you to sell out ? Greediness ? then that will End you out for sure .
Not unless you are willing to Risk long term , Better to sell your coins right after hitting a Good profit.
