Dear nitinji,
Tatasteel on weekly timeframe is in downtrend, looking at pattern wise it seems to be in a potential symmetrical triangle formation. The natural support line of triangle coming around 220-230 zone. Although its a pattern formation price may or may not correct upto there. Remember this is a long term view.
Coming on daily charts, price are in downtrend trading into a channel running from since July 2014, after prices correcting forming a double top. A short term channel got broken recently, alongwith midline of major channel. So stock exhibited a short term sign of strength here.
Looking at daily closing yesterday, stock gained ground closing above 305-307 resistance zone. A positive momentum divergence also formed and stock moving up, overcoming 316 levels will provide impetus to rise till 322-330 levels. A good sign as of now. is momentum seems to be bottoming in short term.
A case of weakness settles once stock closes below 300-303 levels. Till then its a pure divergence play here.
