this is a good example for a stock trading beginner:
bought tesla 100 share at $204
bought tesla 100 share at $186
bought tesla 100 share at $160
the only stock loosing money is tesla in my account, now the average cost of tesla is: $184.
i know my only mistake is not stoping loss when tesla goes downtrend from $204 to $192, which is about $1200 loss only, 沒有及時止損的後果演變成 $5660 帳麵虧損.
現在有兩個思路：
1: 如果tesla 往上走，到$180 or 最好到 $186, 清倉。
2: 如果tesla 往下走，到 $ 140， 再買 100 股， 到 $120 再買 100 股，這就是一條道走到底。
牛人說說，那個思路好呢？
