USD/INR has evolved within a large consolidation since last October forming a triangle. The pair recently approached the upper part of the formation resulting in a pullback. 

April low of 81.60 is an important support. In case this gets violated, there would be risk of a deeper down move towards projections of 80.50/80.10.  

A triangle denotes clear direction is lacking. The pattern has formed after an elongated up-trend. A move beyond the upper limit near 82.95 is essential to affirm resumption in up-move.
