If we make the assumption that this is just a correction from the bull run, I have drawn 61.8% fib retracements from key starts of bull runs, from the very start in mid 2015 to the recent runs that broke the 2017 channel. All other factors ignored for this perspective.
This leads to a reversal zone of 7500 to 9300.

If we continue to go down, then its looking like a bear market is in play
