when to sell?

I bought in at 7.93 should I set it to sell 1/4 of my stock at 20, then 1/4 at 40 then 1/4 at 100? Is that how the sell function works? what's the thought process?

For everyone abiding by the diamond 💎 hands warcry, you're still gonna sell at some point right? I ask because haven't seen a warcry to sell come through. is that going to happen at some point?

thank you in advance. this is a great community.
