Remember data on switching order mode

Hello there,

in "New Order" window, when I change from a mode to another ("Market Order", "Limit Order", "Stop Order", "Stop Limit Order") the sell/buy selector and other order data (where possible) should really remember my choices in precedent mode.

It happens that while I am inserting an order in "Stop mode" the price change and I want to place it at market price in zero time. I switch to "Market order" and all inserted data are gone. In this case I simply miss an entering chance and miss the trade. I'd like to find data being inserted in a mode in other modes, if I switch mode. Or, in alternative, when "Place order" change its status to disabled you should show an active button "Place at market price now".

What do you think about that?
