NIFTY swing Idea

NIFTY broke below a crucial reference point, more importantly it has a high at a pivot swing low ( remember the idea of supports turning into resistances) :)
well here is a low risk short idea looking for a 100% retracement of the swing- this points to a target of 10200-150. the idea is we had retraced fully the journey made from 10500-10950, form a box for that move and extend the box on the lower side to arrive at potential target areas. the trade become invalid for a close above 10600
