I have lost count of the number of trades I got out prematurely. Now, I try to be patient still, you cannot be sure 100% that you got out near the top of the move. Picking tops and bottoms is pretty hard. Now, other traders use risk vs reward to determine their exits. If the risk in their trade is $1 and they bought in at $10. The moment it touches $11 which 1 x risk, they sell some shares then, at $12, at $13, etc. Or you can use percentages say the stock goes up 30%, you sell some shares, another 30% or now at 60%, you sell some more shares. These are other traders methods and not mine. My method is different but, I will keep it to myself.
