As more players work out what TRF is potentially worth, it is hard for buyers to get set in this one without paying up.
I believe that 50,000 bid in the preopen at $1.80 is an attempt to get $90,000 worth of TRF without having to pay up by giving sellers a chance to offer some of their shares.
Try bidding for 50,000 or 100,000 TRF now during trading hours. The bidder gets gazumped.
It has even happened now with bidders up to $1.85!
