BUY and SELL buttons

Hi when I switch between the four sections Market, Limit etc.. the system should not have a default BUY and SELL set option. In other words, if the trader wants to execute his order, he has to press the BUY or SELL button - he cannot go straight to pressing the PLACE ORDER button.

Its happened to me a few times when in the heat of the moment, I press the PLACE ORDER button and execute the wrong direction order. Please at least enable this to be an option.
