Can some one tell me on mpc there is some one with 9032 and that seller wanted to sell at 13040 this morning and then went up to 13050 and came down to 13020 and now is it 12945 . I phoned ost and they said some other markets can amend the price . So now my shares keep moving up and can not sell , because of some people move around their price . Why can't we do it ? Is this Fair ? Maybe Simon can answer that one .
