Investors have developing proof of a successful rebound from near 3200 and are waiting for a new rally above 3230.

The first rally target is the recent Index high near 3260. A move above this level has a stronger resistance barrier near 3280 reached in 2016 November. This is a psychological resistance level . A breakout above 3280 can develop into a strong continuation of the uptrend towards a long term target of 3400.
