Anyone trying to manipulate wouldnt be so blatant. Stop seeing conspiracies where there is just a novice buyer (probably) at work. In any case, the buy occurs at the first sell price, not the bid price.
And for 25k, given the volumes on the board, no-one is going to shift their offers.
Now, if it was 2.5M, that wouldnt be manipulation, that would be strong interest - wouldnt it? So its a fine line.
Sugggest you let the ASX worrk about what does and does not constitute manipulation
