Nifty Spot – 15 Min Chart Analysis:

The current recent market structure is showing Lower Highs (LH) and Lower Lows (LL) — indicating a downtrend.
However, if price moves up first and taps the 25,000 level, it will break the previous high and form a Higher High (HH).

This would signal a Change of Character (CHoCH) or Market Structure Shift (MSS).
If that happens, the trend bias could shift to the upside, and it would be better to wait for a pullback and look for a long entry.
