HCLTECH seems to be in the wave 5 of impulsive phase of Elliot wave. Wave (i) of wave 5 itself is ~240 points so the wave (iii) itself need to cross current LTH of 1698 so the full length of wave 5 can go up to 1880 that is 200% retracement of previous LTH of HLTECH - 1377.
This will be confirmed/supported if Nifty IT index too confirms C&H pattern.
