I am wary of big bids placed pre-open as they could be pulled off just as quickly.
It is also something that has been used quite often of late as more traders are making money on momentum trades which are started by big bids at beginning of day.
I have made money on EBR in past but always careful as it is easily swayed one way or another. Hit 20 after the feeding grenzy recently.
Having said all that, it could be the genuine article.
