Based on intraday cycle analysis there are two possible reversal time periods. One is on Wednesday after 13:40est and the next one on Thursday, around 11:00 est . As a confirmation one can use a divergence with your favorite indicator. This should work well for daytrading. I do not think this will be any major reversal because day cycle is not completed yet .
Wow, can I bet my money on it! I too use divergence but I, from now on, will drop the silly market randomness theory and stick to your crystal ball!
