Hi
1) I download the Apple daily stock market from Yahoo Finance.
2) Import the data into SAS, work perfect.
PROC IMPORT DATAFILE="\AAPL.csv"
OUT=Apple DBMS=CSV REPLACE;
GETNAMES=YES;
RUN;
3)I set the trading day, work perfect.
DATA APPLETD;
SET Apple;
IF weekday(Date)=2 or weekday(Date)=3 or weekday(Date)=4 or weekday(Date)=5 or weekday(Date)=6;
RUN;
4) Try to use X12, but there is error :
ERROR: Time ID variable Date contains gaps.
PROC X12 DATA=APPLETD Date=Date;
VAR AdjClose;
x11;
output out=out a1 d10 d11 d12 d13;
RUN;
TITLE;
Thanks for the answers
