Cboe is experiencing a systems issue which is preventing the SPX underlying price to properly update at Whispertrades. This is an issue with Cboe's systems and must be resolved by Cboe.

Our bots can only read the last known price for SPX. Options quotes continue to update. Without and accurate underlying price, options greeks (delta) are inaccurate, and any bot entries or exits based on distance from underlying may not be accurate.
