This gap up was basically a exhaustion but due to exuberance the price moved further away despite the bearish setup but now a correction is awaiting to happen after this irrational move. Also, a bearish harami candlestick pattern has been formed on the daily chart followed by a indecisive candle and then again with a bearish candle suggesting a downtrend.
Therefore, considering all the above points, a break below the current support, as per fibonacci levels i.e 436 will initiate the trade for the targets of 430, 421, 407 with an SL of 449 on closing basis.
