well supported?

Today' s markets were opened in line with expectation -4% to -6% and closed with a remarkable recovery from the lower levels.  The unexpected support extended by Doemstic institutional investers at lower levels alongwith very strong coverup of shorts in index, stock futures by FII clearly shows that for a short term our markets may bounce upward.  At present US markets were in deep red. This will result the very deep red in global markets for the next day.  But, tomorrow our indian markets,  if opens in red, will bounce further.  This may be certain.  One has to exit puts and  buy calls of 4200, 4300 only.  Nifty upper resistances may be 4150-4250. ( A very small range? This may be studied as per next day's open interest data and fed decision).  As the international economy is at the worst phase/stage, the hanging axe may fall on our markets at any time.  Don't forget to take shorts around nifty 4250 with a target 3800-3600-etc downside in this settlement or in the next settlement.
