It looks like Nifty is forming a IVHS pattern on 15/30 min TF. The neckline of IVHS is around 17480-17500 levels which will be a strong resistance.
RSI is showing divergence in 30 min TF which might indicate an upmove. 17200-17250 is the next strong support for Nifty which is very close to the CMP and hence, a short trade might not be a good option.
However, US market and tomorrow morning's opening will be a key deciding factor on trend for next week.
This is my personal opinion on Nifty just for educational purpose and kindly trade as per your own analysis.
