In weekly chart we can see a clear breakout in Nava ltd. 231 range was the all time High. Recently that level brokered therefore it should turn as immediate support range.
Stock has a potential to reach 400 level in coming days. For that it has to sustain above 250 price level in weekly chart.
195 will the SL.
