控制风险：一点心得和教训。

11/07/2006 进了100 RMBS和200 OVTI。进点都不是很好，究其原因是因为自己对风险的控制不好。

RMBS：我看的support 位点是 21，原因有二：1）这是上次急拉升后的成交量很大的地方。2）在过去的四五天里，虽然在震荡，但是都没有碰到21。
虽然我看21，但是我进的位点是 21.96, 这样我的potential loss 是0.96/21.96 = 4.4%。这样的loss太大了!!!
正确的符合我性格的做法应该是：set a limit order at a price not exceeding 21/0.98 = 21.43, in this way, my biggest loss is 2% on this trade. Of course, I will loss some opportunities because of this tigtht range, but it limit my potential loss!

The reason I want to get in in a hurry is because I was afraid that the stock would fly in the next moment. But actually based on my limited experience, usually stock won't fly but drop. So, next time if want to play, the price I should get in is:  ( < stop price/0.98 ).  If the price won't be back to this range, just let it go.

OVTI: Basically I followed SDrider's call and FEEL current price is a support level. If later on this trade turns to be a profitable trade, it is totally because of luck. I should not buy this stock.

I should focus on the stock I am familar with, like CAAS.
