By the way, I like your chart. It's very creative. Just on the big volumes the obvious is that market is close in time to bounce in both directions (50/50 bets is already not that much risky)! On your chart, first blue box we've got upward direction, and the second and third ones - we have a downward push. Anyway, this still gives an indicator that we are about the expect something more than a clumsy hour with the candlesticks. Mind well, though, that enhanced volatility may result in big different between highest, lowest and close price. Therefore, we should still wait and ensure enough margin reserves in order to survive any psychic attacks of the market! Good luck!
