SBIN has just missed its 4th wave by 4 points to make its ED or wedge invalid. So, till now, it is safe to say SBIN will move towards 313/15 in three wave move for a fall. This will be again invalid if it moves further 316, but still it will be a reversal point for another two reasons=
1. Formation of a triangle
2. Major support at 315/16 level
