Function to handle Trade bbetween accounts

hello, im trying to automate loot giving between multiple accounts and im implementing th etrade window, i can do pretty much everything expet two things.... the first window with the View button, i cannot seem to find a way of acknowledging the trade.

and on the other side, the starting of the trade, i tried using TradePlayer($aAgent) but it doesnt work. nothing i try seems to initiate the trade action, what would i be doing wrong?

can anyone give me some pointers on how to perform this?

thanks in adavance
