Description:
How to calculate Parabolic SAR on a 5 days basis of stock data? 
all weeks except the first week must have 5 days, where the date is the first date of the week series.  
the OHLVC is calculated as: 
O = First Open, H = Highest High, L = Lowest Low,  
C = Last Close, and V = EMA average. 
Input Sample:
CODE,DATE,OPEN,HIGH,LOW,CLOSE,VOLUME  
AIQ,03/02/09,2.91,2.98,2.54,2.54,2845000 
AIQ,03/03/09,2.60,2.64,2.44,2.46,3036900 
AIQ,03/04/09,2.51,2.84,2.47,2.78,7518800 
AIQ,03/05/09,2.71,2.71,2.50,2.56,2468700 
AIQ,03/06/09,2.58,2.91,2.56,2.89,2962900 
AIQ,03/09/09,2.63,3.59,2.52,3.03,3380300 
AIQ,03/10/09,3.19,3.59,3.05,3.58,7604400 
AIQ,03/11/09,3.48,3.60,3.41,3.55,2349100
Output Sample:
DATE_GROUP TIME FIRST_OPEN HIGHEST_HIGH LOWEST_LOW EMA_VOLUME LAST_CLOSE SAR 
03/04/09 00:00 2.91 2.98 2.44 5245866 2.78 2.98 
03/11/09 00:00 2.71 3.60 2.50 4046566 3.55 2.44
