1.Don't stick to NT any more. There are 4000+ stocks traded at Nasdaq and you can find other stocks with much better chance by studying my daily market report.
2.Don't understand what you're talking about
3.Don't risk your RRSP money at stocks. Buy income/balanced mutual fund for tax saving purpose. Please refer my previous post regarding rrsp by searching rrsp
