Re: File No. SR-CboeEDGA-2019-012
Dear Ms. Countryman:
The Investment Company Institute1 is writing to express opposition to the proposal by Chicago
Board Options EDGA Exchange, Inc. (“EDGA” or the “Exchange”) to establish the Liquidity
Provider Protection delay mechanism (the “Access Delay”), which intentionally would delay all
liquidity taking orders by at least four milliseconds in order to allow liquidity providers time to adjust
their quotations in response to new market data.2
We strongly oppose the Proposal because, among other things, it:
(i) would unfairly discriminate against liquidity takers as well as liquidity providers that are
unable to update their quotes within four milliseconds;
(ii) would introduce intractable complexity to the duty of best execution and the market
structure generally; and
(iii) is inconsistent with a fair and efficient national market system under Section 11A of the
Securities Exchange Act of 1934 (“Exchange Act”).
For these reasons, as described below, we believe the Proposal is inconsistent with the Exchange
Act and the Commission therefore should disapprove it.
First, by asymmetrically applying the Access Delay only to orders that take liquidity, the Proposal
would unfairly discriminate against market participants that are primarily liquidity takers, which

include most retail and institutional investors.3 These investors would no longer be able to rely on a
displayed quotation on EDGA because liquidity providers could modify or remove that quotation
during the period of the Access Delay.4 The Exchange argues that this discrimination is justified to
encourage market makers and “any of a wide range of other market participants entering resting
limit orders” to provide liquidity by preventing those resting orders from “being picked off by
opportunistic traders.”5
That purported rationale, however, fails to acknowledge that only one category of liquidity providers
could benefit from the Access Delay: fast liquidity providers that are capable of modifying their
quotations on EDGA within four milliseconds following a change in market prices. In fact, any
investor submitting a limit order that joins the best bid or offer on EDGA but which is unable to
cancel or modify its order within four milliseconds would face the risk of an adverse execution
against the opportunistic traders.
The Access Delay, therefore, favors only sophisticated, low-latency market makers at the expense of
liquidity takers, who would lose efficient and reliable access to displayed liquidity on the Exchange,
and slower liquidity providers.6 We further believe that this unfair discriminatory structure would
impose an undue burden on competition on liquidity takers and slower liquidity providers and does
not further the protection of investors or the public interest.7
Second, the Proposal could significantly complicate the duty of best execution and would exacerbate
market complexity more broadly.
The Exchange states that while market participants would not be required to access liquidity on
EDGA under Regulation NMS because EDGA quotations would not be protected, market
participants “would be permitted to send orders for execution on EDGA” consistent with the duty
3 Section 6(b)(5) of the Exchange Act requires that the rules of an exchange not be “designed to permit unfair
discrimination between customers, issuers, brokers, or dealers.” 15 U.S.C. 78f(b)(5).
4 The Access Delay also may increase incidents of trade throughs on the Exchange. For example, when an investor
sends a marketable sell order to EDGA, the best bid made ticks up on another market during the Access Delay. To the
extent the EDGA liquidity provider does not update its quotation to match the new best bid during the Access Delay,
there is no better priced hidden liquidity inside the spread on EDGA; and the order is not routable to the trading center
with the new best bid; and therefore the execution following the conclusion of the Access Delay would trade through
the superior bid available on the away exchange.

6 Moreover, under the Proposal, the low-latency market makers capable of benefitting from the Access Delay, at the
expense of slower liquidity providers and liquidity takers, would be under no obligation to improve market quality. The
Commission has stated that “while exchanges may legitimately confer special benefits on market participants willing to
accept substantial responsibilities to contribute to market quality, such benefits must not be disproportionate to the
services provided.” Exchange Act Release No. 67437, 77 FR 42525, 42527 (SR- NYSEAmex-2011-86) (disapproving a
proposed rule change that would allow certain market makers to access certain order information unavailable to other
market participants).
7 See 15 U.S.C. 78f(b)(5) and (8) (requiring, among other things, that the rules of an exchange be designed to protect
investors and the public interest and to not impose any burden on competition not necessary or appropriate in
furtherance of the Exchange Act).

of best execution.8 This framing of the duty of best execution may suggest that broker-dealers have
the option to consider or ignore EDGA quotations even where EDGA quotations are better than
the best protected quotations. It is difficult to imagine a scenario where a broker-dealer could
ignore a better priced EDGA quotation to fill (or partially fill) an order without potentially inviting
claims that it may be violating its duty of best execution. Even if a broker-dealer consistently found
that it is unable to reliably access EDGA quotations because liquidity providers modify their quotes
during the Access Delay, it nevertheless could face regulatory scrutiny, including from the Exchange
itself, as to why it did not route or attempt to route to a better priced EDGA quotation.
The Proposal would exacerbate market complexity generally by establishing a harmful precedent.
Other exchanges may similarly adopt manual quotations and access delays of varying lengths, which
will undermine the efficacy of the Order Protection Rule and further complicate a broker-dealer’s
best execution analysis.9 As additional exchanges adopt access delays of varying lengths, broker-
dealers would have to account for each separate delay in determining which quotations are
immediately accessible, further complicating routing decisions. Broker-dealers also would need to
separately account for the national best bid or offer and the best protected bid or offer to ensure
compliance with both their duty of best execution and the Order Protection Rule.10 If the Proposal
is approved, exchanges subsequently might propose specific order types that are exempt from these
asymmetric access delays adding further complexity to the market structure. As a general matter,
increases in market complexity benefit the most sophisticated market participants to the detriment
of less sophisticated investors, and raise costs for everyone.
Third, the Proposal is inconsistent with a fair and efficient national market system under Section
11A.11 A fundamental principle of the national market system is that immediate access to quotations
facilitates the efficient pricing, display, and execution of orders. It is primarily for this reason that
the Commission stated when adopting Regulation NMS that “a trading center’s systems should
provide the fastest response possible without any programmed delay.”12 The Proposal would retreat
from intermarket price protection and efficient access to the Exchange’s quotations by allowing low-
latency liquidity providers to modify their displayed quotations. The Commission has recognized
that the ability of investors to timely access firm, displayed quotations is a cornerstone of open, fair,
and transparent markets.13

sizes posted on the Exchange as well as other factors such as the likelihood of execution.

particularly if other exchanges similarly adopt “manual” quotations that are electronically accessible.

In sum, we believe that the Proposal’s potential benefits solely would inure to a few low-latency
liquidity providers, The direct harm to liquidity takers and slower liquidity providers as well as the
disruptions and complexity that the Proposal would introduce to the market greatly outweigh those
potential benefits. For these reasons, we strongly urge the Commission to disapprove the Proposal.
