Nifty made a double top compared to the previous session but ended marginally higher. Large volumes and range moves mean that a lot of churning seems to be happening between sectors and stocks. With no reversal signs on the horizon, Nifty could rise towards 18,115 over the next few sessions. On the other hand, a breach of 17,833 could mean faster downsides. Indian markets could open flat to mildly lower, in line with mixed but rangebound Asian markets today and mildly positive US markets on Thursday.
