I wouldn't be buying on open, then again I bought in 2009!!
Will be another gap up on open now, io sitting at 8.5 & 10 atm.
Norm is it drops back after 11:00, this could be a big volume day for SSN, so make a coffee and watch the action.
Probably a 50 mill turnover day again, so there's going to be many a trading op during the day.
Good luck with it.
