Regex Tester & Validator

This regex matches EIM (Energy Imbalance Market) location spread instrument identifiers with named capture groups. It parses structured energy trading codes containing asset '02', two market locations separated by a slash, Calendar Year (CY) contract type with Long offset, Physical (PHY) or Future (FUT) derivative type, and a 4-digit year. Used in energy trading systems for validating and extracting components from spread instrument names.
