"What is meant by restrictions is this: they no longer offer you a fixed price service. A bookmaker’s point of difference to the TAB and its totalisator system is they offer fixed price to their clients. The odds are locked in at the time of placing the bet, where as TAB totalisator system is a pool of money that is distributed by weight of money for a particular result. So by not allowing you to bet fixed price with them, these bookies are effectively closing your account as well."
