Ann: Trading Halt-NSL.AX, page-67

@jorgo: You can start queuing now, but I would advise you to be very careful with market depth at this time when in trading halt. You'll see that the buys and sells will disappear on release on the announcement. People will put in fake buys and sells in order to trick amateur investors into thinking a certain way.

IMO place the order once you know what you are buying into i.e. read the announcement carefully first.

Bad news can be overwhelmed by the good news and only the savvy investors will be able to decipher the messages in the announcements.

Edit: To add to the above comment, don't believe indicate price too much. I could easily put a fake bid of 10m units at 10c and that would change the indicative price.
