i know it's market deciding, but how it's done?

i mean traders see on the board of all values, down or up, but how are those values are obtained?

there's a bid-ask spread. when more people sell than buy, - Enlighten (80 bytes) 2008-10-07, 16:28:53 (265170)
- it has nothing to do with how many sellers or buyers - meiyou (209 bytes) 2008-10-07, 18:51:37 (265182)
- correction: bid will be lower than ASK (无内容) - Enlighten (0 bytes) 2008-10-07, 16:29:33 (265171)
  - correction again, bid-ask is the profit for the middle men. - Enlighten (191 bytes) 2008-10-07, 16:39:43 (265172)
Someone bid, others answer the bid (无内容) - HunHunSheng (0 bytes) 2008-10-07, 15:54:21 (265161)
