When to use this pattern

This pattern is drawn from the Finance > Securities & Trading category and carries a ReDoS-safe certification. That matters for Python developers because particularly important in Python web servers where CPU-bound regex operations can stall concurrent request handling. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Common Pitfalls

Month codes are a historical convention, not alphabetical. 'I', 'L', 'O', 'P', 'R', 'S', 'T', 'W', 'Y' are not used as month codes. The year rolls over — Z24 is December 2024.

Technical Notes

Month codes: F=Jan, G=Feb, H=Mar, J=Apr, K=May, M=Jun, N=Jul, Q=Aug, U=Sep, V=Oct, X=Nov, Z=Dec. Common roots: ES=S&P 500, CL=Crude Oil, GC=Gold, NQ=Nasdaq 100.
