Looks like it'll be back in 926 BookTrader Support Instantaneous Order Transmission. Support for single-click order transmission has been reinstated in the BookTrader. This ability had been deprecated in favor of an order confirmation message. Customers can now elect to turn off the Order Confirmation by selecting "Don't show this popup dialog again" when they click in the ladder to create an order. Once the order confirmation message is turned off, clicking in the price ladder will instantaneously submit an order at the specified price.
