[+5] u/Accurate_Shift_3118: In all honesty, CME documentation related to exercise style tends to be oddly inconsistent. I had to check this for myself when running derivatives workflows on Runable because certain brokers’/documentation sites’ terminology differs. As far as I recall, the majority of conventional commodity-based futures options (CL/GC/SI/NG) are American-style, whereas the exercise style of index products depends on their expiry terms.
