#5 Display price to confirm transaction

[Aseem]

Is it an easy change to try and display the price a market maker would execute the requested transaction at, before executing the transaction itself?

For example if the price and quantity entered would drive the market maker's price up to a level greater than the requested price such that the remaining quantity would have to be put onto the limit order book, is it possible to display the quantity and price satisfiable by the market maker and asking for the user's confirmation, before actually executing the transaction?

Thanks.

This used to be medium hard. I wanted the effect, but I wasn't looking forward to reimplementing all the calculations in javascript in order to be able to tell users the prices before they submit requests. Now that I've integrated AJAX, it should be much simpler. I haven't tried to figure out the scope, but this sounds like a useful feature and it's much easier to think about now.
