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, 没有及时止损的后果演变成 $5660 帐面亏损.
现在有两个思路：
1: 如果tesla 往上走，到$180 or 最好到 $186, 清仓。
2: 如果tesla 往下走，到 $ 140， 再买 100 股， 到 $120 再买 100 股，这就是一条道走到底。
牛人说说，那个思路好呢？
