Why are some strikes way more liquid?

[murray t turtle]

People love whole numbers, it must be a psychological thing. Round numbers are always more popular and memorable with people. When professional athletes reach new milestones/round numbers in their stats, everyone gets excited. The trading world, wall street, is also obsessed with whole numbers, psychological, breakthrough barriers in charts. Funds buy options by the whole, round, numbers...that's why the volume with whole numbers is so much, obviously, more.

Clearing
OTC Products


In 2014, OCC began offering clearing services for OTC products on S&P 500® index options. Transactions are transmitted to OCC via an approved OTC Trade Source and are guaranteed by OCC through a similar novation process as other OCC cleared products.

OTC options must be negotiated and matched OTC (not transacted on an exchange or exchange-like market). Clearing member clients must be eligible contract participants.

SEC No-Action
Following is a "no-action" letter from the SEC to OCC with respect to cleared OTC options and Exchange Act Rules 15c3-1 and 15c3-1(a). OCC received no-action relief from the SEC to permit OTC options to be treated the same as other listed options for purposes of Rule15c3-1, enabling broker dealers to use an approved theoretical options pricing model to calculate capital charges for positions in OTC options and market makers to trade in OTC options without making themselves ineligible for capital treatment.

In addition, the minimum capital charge for each OTC option under SEC Rule 15c3-1 will be $0.75, adjusted as appropriate for the size of the OTC option, not to exceed the market value in the case of long contracts in OTC options.

Excellent. Thank you for this Alex. It seemed that we started out a bit too confrontational. Every source I looked at including the OCC website, OCC email contact and a call to the OCC gave different information. That's why it was a bit frustrating for you to simply say your wrong or "good trading". It is much more helpful to see something concrete that shows different information.
