It happened twice for me. At first, I thought Labu dropped enough 

and I started to buy, however, it continued to drop until 

it reached 19, then bounced back. The trend reversed, however,

i already sold my shares. the stock reached 54 rencently. 

I then started to buy Labd from 20 till it dropped to 15, by the time it bounced back to 19, then I heared Seabird said should take profit and exit, I did, now it is 

23. 

Have a plan, if first buy failed, take a loss, try to buy back at 

a lower price, doesn't work, then take a loss again. 

Wait till it drop further. 

 When trend breaks and established, be brace to buy large amount.
