In the coming session, we expect the bias to remain positive as long as Nifty sustains above the 11,970 mark. Thus, intra-day cool-off towards 12,030-12,000 should be used as a buying opportunity. On the higher side, the level of 12,155, followed by 12,200, would be seen as the next resistance zone for the index.
