Dear nitinji,
Dr Reddy is in secular uptrend. The key levels to watch are shown on chart with explanations. Remember for trend to mature, either it will end the parabolic move with steepfall or you should be on alert when stock is rising on after third or fourth base on your timeframe. For ex; four bases on weekly got complete indicated any rise from hereon will or can be a trigger for trend reversal. Stock cant rise till eternity.
We as a trend follower only needs to latch on the trend with key reversal in hand.
For extreme short term on daily, i will be on alert if stock closes below 4130 levels, it can test 3900 zone.
