Nifty approached final level, correction coming- SHORT

This Nifty rally started from Dec 29th when index made a low of 7893, since then we didn't see any correction in Nifty. For me Nifty's highest possible level was 9540 which is almost complete and its on gann resistance level. I would go short nifty around 9500-9540 with SL of 9750 and target would be 9000-8800 in three to 4 month.
