REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders of Applied Finance Valuation Large Cap ETF
and Board of Trustees of ETF Opportunities Trust
In planning and performing our audit of the financial statements
 of Applied Finance Valuation Large Cap ETF (the 'Fund') as of
and for the year ended December 31, 2022, in accordance with the
 standards of the Public Company Accounting Oversight Board
(United States) (PCAOB), we considered the Fund's internal
control over financial reporting, including controls over
safeguarding securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form
 N-CEN, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion.
The management of the Fund is responsible for establishing and
maintaining effective internal control over financial reporting.
 In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and
related costs of controls. A fund's internal control over
financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in
 accordance with generally accepted accounting principles (GAAP).
 A fund's internal control over financial reporting includes
those policies and procedures that (1) pertain to the maintenance
 of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the
fund; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial
statements in accordance with GAAP, and that receipts and
expenditures of the fund are being made only in accordance with
authorizations of management and trustees of the fund; and (3)
provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use or disposition of a
fund's assets that could have a material effect on the financial
 statements.
Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future
periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.
A deficiency in internal control over financial reporting exists
 when the design or operation of a control does not allow
management or employees, in the normal course of performing their
 assigned functions, to prevent or detect misstatements on a
timely basis. A material weakness is a deficiency, or combination
 of deficiencies, in internal control over financial reporting,
such that there is a reasonable possibility that a material
misstatement of the Fund's annual or interim financial statements
 will not be prevented or detected on a timely basis.
Our consideration of the Fund's internal control over financial
reporting was for the limited purpose described in the first
paragraph and would not necessarily disclose all deficiencies in
 internal control that might be material weaknesses under
standards established by the PCAOB. However, we noted no
deficiencies in the Fund's internal control over financial
reporting and its operation, including controls over safeguarding
 securities, that we consider to be a material weakness as
defined above as of December 31, 2022.
This report is intended solely for the information and use of
management and the Board of Trustees of the Fund and the
Securities and Exchange Commission and is not intended to be and
 should not be used by anyone other than these specified parties.
