A Bloomberg futures ticker usually looks like:
MCDZ3 Curcny
where the root is MCD, the month letter and year is Z3 and the 'yellow key' is Curcny.
Note that the root can be of variable length, 2-4 letters or 1 letter and 1 whitespace (e.g. S H4 Comdty).
The letter-year allows only the letter listed below in expr and can have two digit years.
Finally the yellow key can be one of several security type strings but I am interested in (Curncy|Equity|Index|Comdty) only.
In Matlab I have the following regular expression
expr = '[FGHJKMNQUVXZ]\d{1,2} ';
[rootyk, monthyear] = regexpi(bbergtickers, expr,'split','match','once');
where
rootyk{:}
ans =
'mcd' 'curncy'
and
monthyear =
'z3 '
I don't want to match the ' ' (space) in the monthyear. How can I do?
