Mam, I guess, it is on the top of the trading range, and it forms a large bull trend bar due to the vaccum effect as the strong bears were waiting for the top level of the range to be tested . The absense of those bears made the imbalance, and whenever there is an imbalance, maket moves very quickly. Also if it goes beyond the resistance the magnetic pull seems to be very strong. So there is high probability of the downward breakout.
