Currently, ICICI Bank made a rebound after a correction. Levels of 747, 765 and 805 can be immediate resistance on the way up.
If the rebound fails, then, look for strong support at 710, below which 692 is another support zone.
Also, 734-682 looks like consolidation range and hopefully the stock should stay in this range if it falls.
Going bullish, a target of 843 and 974 in the medium to long term looks probable.
