I don't pre-set a target. ( I don't day trade)
I do have a plan with specific criteria of when I will exit a trade. When that criteria is met I'm out. There is no wondering what I should do. The trade is over and what happens afterward is something I have no control over. I can only control what I do not what the market does.
No sellers remorse, no woulda, shoulda, coulda; It is one trade out of many and if I followed my plan it was a successful trade.
My trade on FSLY and OSTK, these trades hit my preset target and I was out of those trades. IF I let them run, I "woulda" double/triple my profit. I want none of that because I have seen money on the table just evaporate in a blink.
