Nasdaq Enhances Holding Period for Midpoint Extended Life Order


Nasdaq created the Midpoint Extended Life Order (M-ELO) in 2018 to help institutional investors with longer-term investment horizons interact with each other at the midpoint of the National Best Bid and Offer (NBBO). There is a built-in holding period before a M-ELO order can be executed, to protect M-ELO orders from negative price impact.

Nasdaq recently announced a reduction in the holding period from 500 milliseconds, or half a second, to 10 milliseconds:

Effective Monday, May 11, Nasdaq is optimizing the M-ELO timer by reducing the holding period from 500ms to 10ms. This enhancement will broaden the spectrum of order type use-cases and opportunities while sustaining its strong performance characteristics. M-ELO remains the highest performing order type among its peers, providing a purpose-built midpoint solution to minimize market impact on the single largest exchange in the U.S.

Benefits of M-ELO and M-ELO + Continuous Book Orders:

· Interact with like-minded investors

· Increased availability for algo and routing strategies

· Highest quality of execution at the midpoint of the NBBO

During March’s unprecedented volatility, M-ELO’s quote stability remained consistent and the M-ELO order type outperformed all other venues, including those offering a delay mechanism.

Absolute market response shows the low impact and trade footprint of a M-ELO execution.
