trading can begin at any time. all trades go through once the accept button is clicked. once i log in and see this trade, if for any reason i feel this deal is lopsided i have veto power
if you make a trade before yahoo opens for business. then you need to post the deal here. and both parties must confirm the deal before it is executed
but again, ive commished for 5 yrs. seen about 200 trades. have not had to veto a single deal......yet
