Its seems like a second pullback after Idea-Vodafone merger. If the price goes up on the coming days with considerable volume - its a LONG opportunity; however keep the stoploss just below the trend line.
Overall trend is down. If goes down, then it will support near 430 area. Since there was a huge volume when it reached the support of 430 last time, this time its gonna be difficult. SHORT if the next candle is red with huge volume.
