Meet CHX's Innovative Liquidity Enhancing Access Delay℠ (LEAD)

SEC Approves LEAD and LEAD Market Makers

CHX's innovative Liquidity Enhancing Access Delay℠ (LEAD) was approved by the Securities and Exchange Commission (SEC) on Thursday, October 19, 2017. On October 24, 2017, the Commission stayed the approval of LEAD, pursuant to Rule 431 of SEC Rules of Practice, which is now subject to Commission review.  The approved rules provide for the creation of a new category of Market Maker – LEAD Market Makers (LMMs).

In the event the stay is lifted, CHX will announce an implementation schedule.

CHX is currently accepting applications to become registered Market Makers at the exchange.  CHX Participants interested in being assigned as an LMM must first be approved as registered Market Makers.  Initially, a limited number of LMMs will be assigned to each securities traded at the Exchange to assure that there is sufficient capacity for the anticipated increase in activity.  LMM assignments will be phased in on a security-by-security basis on a schedule that CHX will announce.

Links to the details of LEAD, LMMs, and CHX's implementation plan are provided below.
