A minor up swing on the anvil ?

After yesterday's jumbo crash of 258 points, Nifty was range bound between 4155 and 4230 today (7-7-09) and closed at 4202 with a gain of 36 points. As tomorrow's Agni level is at 4230 it is likely that Nifty may give buy signal by moving above that point. If it moves above 4230, shorts is to be covered for getting opportunity to short again near upper band of Sudha Rishabham ie. near 4348.
