May I ask your help (or where to look, or who to consult)to find
the appropriate functions or data set up to reference price on prior
days, and subsequent days to answer a question typical of the query
below on the data base sample SP mini CME shown below without having
to do separate columns for all combinations of changes over many days.
I was able to use subset or apply for intraday changes using columns,
but wanted to be able to report changes upon certain conditions by
reference to prior days and subsequent days. Many thanks.
Query: What is the change to open tomorrow after price today
exceeds yesterday's high when yesterdays close < the day before
yesterdays close.
sample data ES3.t column is 1= 9:30 2=11:00 3= 2:30 4=4:00
ES3.p is price open at specified time
ES3.jd is julian date.
c1-c4 are changes one bar to the next
oc is change from open to close
ES3.d ES3.jd ES3.dw ES3.t ES3.p c ES3.c1 ES3.c2 ES3.c3
ES3.c4 oc
