Looks like a possible pull back after the price advance with huge volume. Any positive catalyst can drive the price to new level. However be cautious and set your STOPLOSS 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.
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 .
