In trading some are making take profit with the lvl and percentage,example like
TP lvl 1=20%
TP lvl 2=30%
TP lvl 3=50%
i just want to know what kind of lvl and percentage is the best for that kind setting and any reference that can calculate the setting of take profits
Probably this should be based how much do you know about the coin that you're investing at. If you know it well, and you're confident that it could be a good coin for hodl, then maybe you'll set higher percent of taking profits from it. Like 70%, 100%, or even higher than that.
Best to take profit is when you're satisfied.
