TECHM(Daily)- Having B-Wave Triangle with missing "e"- wave?

From Highs @748 - TechMahindra could be in corrective sequence A-B-C where B-Wave is shaping as the Triangle & Once e-wave within B-Wave Triangle is done, which comes in the zone 520-530 then C-Wave will start on downside & can travel between 340--350 where C-wave will travel 61.8% of A-Wave.
