Market cycle? Has the major correction started?!

NSE:NIFTY   Nifty 50 Index
Details on the chart, it's very interesting.

Draw a triangle for the previous bull rally, copy & paste it on the current bull rally. It fits perfectly.

The previous bull rally from Feb 2014 to March 2015 took 393 days and NIFTY went up by 3185 points.

The recent bull rally from Dec 2016 to Jan 2018 took 399 days and NIFTY went up by 3277 points.

The correction after the previous bull rally took 362 days and NIFTY went down by 2293 points.

So based on the same logic, if the major correction has started, we should see NIFTY tat 9000 levels by Dec 2018?!

Just for study purpose!
