Coach:
If we can assume that because the ES is about 10 points higher than the SPX, then an equivalent trade on the SPX might have been the 1210/1200. Mid on that is $0.45.
However, you're saying that $1.10 would be required to match your trade. If the equivalent trade assumption is correct, then this is a huge difference.
I must be missing some things here, because if this is typical, why would anyone trade spreads on the SPX versus the ES?![]()

well that depends on whether you want to trade the regulars or the EOMsless liquidity in the EOMs so i suppose the regulars would be preferable.

Quote from scoobie27:
Rally, one more quick question. Are the ES option prices dependent or based on the SEP ES futures and not the DEC ES futures?ie the nearest month. So if at expiry, July 21 1280 PUT is 20, does that means SEP ES Futures is at ~ 1260? Thanks
Quote from Aardvark:
ES vs SPX...if more brokers start offering options on ES and ES has tighter quotes and easier fills/liquidity and EOM...hummm I wonder if the CBOE will start giving "true" quote spreads to John Q Public and perhaps easier fills.
