Well...according to Daryl Guppy (In case if anyone don't know who he is, he writes books and stuff, he is a master in trading.)
ONE OF HIS TRADING RULES
IS TO DO NOTHING FOR THE FIRST 20MINS OF THE MARKET.
AT 10:21AM we will know what the big boy wants and then we act on it.
beside...if RBA brings the rate up, AUD will go up more...and that will help Centro.
