build a social media site using dolphin

i want a dolphin module that will add/edit/delete stock trades for record keeping purposes, a trades ledger if you will. there should also be a profit/loss tracking element (formulas to follow) as well as a portfolio summary. i prefer to also have a widget that's part of the module that i can add to the homepage that allows the user to do "quick entry" of stock trades without going into the main ledger.
