The EW structure of Dr Reddy is very classical & a textbook type. It seems we have a Flat Correction in Wave (iv). Wave a=b and Wave c has extended exact 1.618.
Besides the retracement of wave 4 is 0.382. So we have a Fibo Cluster around 3600 levels. '
So the probability of Wave (v) materialising seems bright in which case we see 4200 levels.
