Trendline Support is the base for this one.
Retesting after the breakout, provides a low risk entry opportunity. Levels mentioned in Chart.
INDUSTOWER Weekly chart is presenting a potential entry as it is consolidating after good volume. Breakout from this consolidation range (marked in the chart) will be ideal time to add more. If and when the price moves up to test the previous ATH (All Time High), good profit can be booked.
NIFTY seems to be retesting the previous breakout level. Nothing to worry for Bulls as long as the support lines are not breached.
