On request of one of my friend I have analyzed this chart. Here first thing that comes to mind is that the up trend is clear as there is no breach of up-trendline and the stock is making higher bottoms.
next thing that comes is the days with more than avg volume have been white candles (ie there was buying on those days).
There is also seen that there is older resistance (~700) which was broken with a greater volume. Now that resistance line have become support and this is another good sign of bullish phase.
But there is only one concern here that the last volume pick came at the black candle while it took support at 710 (708.1 to be accurate) level. This makes 705~710 level a critical support.
