控製風險：一點心得和教訓。

11/07/2006 進了100 RMBS和200 OVTI。進點都不是很好，究其原因是因為自己對風險的控製不好。

RMBS：我看的support 位點是 21，原因有二：1）這是上次急拉升後的成交量很大的地方。2）在過去的四五天裏，雖然在震蕩，但是都沒有碰到21。
雖然我看21，但是我進的位點是 21.96, 這樣我的potential loss 是0.96/21.96 = 4.4%。這樣的loss太大了!!!
正確的符合我性格的做法應該是：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.
