I agree that the fact that someone can do a BS trade of only 1 share for the sole purpose of manipulation and the ASX allows this is absolutely a lack of care factor for us investors, same goes with the silly games people play by putting in BS orders or sales and then cancel them on opening of the market to try and con investors is pathetic, surely the ASX can put something in place to indentify these practices and either ban or suspend these culprits.
