    Study Notes

    HFT Advantages

    • Liquidity has improved, as measured by bid-ask spreads and other metrics
    • Transaction costs for retail and institutional traders have fallen, mostly due to changes in trading
    • Market structure is closely related to the development of HFT

    HFT Risks

    • Market manipulation using HFT techniques is reported by institutional investors
    • High perceived levels of abuse may harm market liquidity and efficiency for all classes of traders
    • Rising complexity of supervision
    • More frequent technical glitches
    • HFT arms race failures (sniping and overinvestment)

    HFT's Arms Race and Market Design Failure

    • Sniping (tax on liquidity providers)
      • Mechanical arbitrage opportunities are built into Central Limit Order Book (CLOB) market design
      • Arbitrage opportunities violate weak-form EMH
      • Market looks efficient in time space, but not efficient in volume space
      • HFTs earn rents from symmetrically observed public information
    • Arms Race
      • Arbitrage rents induce an arms race for speed
      • Mathematically, a prisoners' dilemma that leads to overinvestment

    Pre-trade Disclosure is Necessary

    • Pre-trade disclosure is necessary for auction mechanisms
      • The Island case study
        • The SEC enforced Regulation ATS, requiring the Island electronic communications network (ECN) to comply with ATS display requirements in several of the highest-volume exchange-traded funds (ETFs) where Island dominated trading and price discovery
        • Island chose to comply by going “dark,” no longer displaying its automated limit order book to any market participant
        • Trading and price discovery continue on Island after it goes dark, but at much lower levels
        • Trading costs (effective spreads) in all ETFs decline in non-Island markets that pick up market share

    Front-running Risks

    • Parasitic traders may seek to exploit the existence of large buy orders by “front running” the order
    • Order matching strategies are used by parasitic traders to exploit large buy orders
    • Traders are more likely to display their orders when the tick size is larger, as the greater tick size makes front-running more costly
    • The parasitic trader has to arrive before the large order in the order book

    Dark Liquidity

    • Dark liquidity (dark pools or hidden orders) is allowed under waivers from pre-trade disclosure in specific situations
      • Reference price
      • Large-in-scale transactions
      • Negotiated trade
    • Matched principle transactions (MPTs)
      • Facilitator interposes itself between the buyer and seller of the transaction, and is never exposed to market risk
      • Transactions are concluded at a price where the facilitator makes no profit or loss, other than a previously disclosed commission
      • MPTs are primarily used to provide access to clearing and/or maintain post-trade anonymity
    • Fiduciary duties towards clients apply (best execution)
    • Organizational requirements for RMs and MTFs
    • No interaction allowed with SI

    Mapping Trading Venue Types

    • OTFs (Order Trading Facilities)

    Trade Reporting

    • Two (pre-trade and post-trade) transparency regimes in MiFID 2 - MiFIR (disclosure to the public) for two sets of asset classes:
      • Equity and equity-like instruments (including actionable Indication Of Interests, IOIs)
      • Non-equity instruments (bonds, structured products and derivatives)
    • Crucial function in financial markets
      • Micro: Price discovery, Market integrity and investor protection
      • Macro: Monitoring systemic risk
    • Transparency is no panacea
      • Market Impact (in particular, pre-trade transparency)
      • Capital commitment (bilateral markets)

    Pre-Trade Transparency in Equity Markets

    • Trading venues shall make public current bid and offer prices and the depth of trading interests at those prices which are advertised through their systems (art. 4 MiFIR)
    • Quotes need to be published even in absence of trade taking place

    Trading Venue Classification

    • The classification of trading venues is a core part of EU legislation on market structure.
    • The objective of this classification is to tailor regulatory action depending on the type of trading venue.
    • This classification is crucial to address various issues, including minimizing "cream skimming" by informed investors, preventing market fragmentation from becoming liquidity fragmentation, promoting an efficient trading environment, and protecting market quality and integrity.
    • Cream skimming refers to informed investors extracting informational rent from uninformed investors, potentially lowering asset quality in the market.
    • EU legislation aims to ensure that organized trading is conducted on regulated venues with full transparency, with internalization being an exception.

    Market Structure

    • Trading venues operate based on different market structures with distinct features, such as order-driven or quote-driven auctions, as well as bilateral trading.
    • MiFID I saw a limited number of bilateral trades (13), while MiFID II witnessed a significant increase in more than 100 bilateral trades, leading to a successful capture of most OTC trades.
    • However, the shift towards public markets has been limited.

    MiFID Trading Venues (Non-Equities)

    • Trading venues in the EU are categorized into two main groups: neutral and non-neutral.
    • Neutral venues include multilateral matching, both non-discretionary access and execution, and riskless counterpart.
    • Non-neutral venues involve bilateral matching, allowing both non-discretionary access and discretionary execution and execution.
    • Non-equity instruments include bonds, structured finance products, emission allowances and derivatives.
    • The EU regulates Regulated Markets (RMs), Multilateral Trading Facilities (MTFs), Systematic Internalisers (SIs) and Organised Trading Facilities (OTFs).

    Organised Trading Facilities (OTFs)

    • OTFs are multilateral systems distinct from regulated markets and MTFs.
    • These facilities allow multiple third-party buying and selling interests to interact, leading to contracts for non-equity assets.
    • While OTFs offer a level playing field with MTFs and RMs, they differ in their execution rules.
    • OTFs operate with non-discretionary access while allowing discretionary execution in terms of matching.

    OTF Characteristics

    • OTFs allow discretionary execution with specific restrictions, including adhering to client instructions and best execution obligations.
    • Although OTFs do not possess proprietary capital, they permit matched-principle transactions with client consent, primarily for clearing and post-trade anonymity.
    • Matched-principle transactions (MPTs) involve facilitators interposing between buyers and sellers, ensuring no market risk exposure.
    • OTFs are subject to the same organizational requirements as RMs and MTFs, including best execution duties for clients.
    • OTFs are prohibited from interacting with SIs.

    Mapping Trading Venue Types

    • A graphical representation of the mapping of different trading venue types, including OTFs, exists.

    Trade Reporting

    • MiFID II and MiFIR establish two transparency regimes: pre-trade and post-trade, for two distinct asset classes: equities and equity-like instruments, as well as non-equity instruments.
    • The transparency regime is crucial for achieving market integrity and investor protection.
    • Trade reporting plays a significant role in achieving price discovery and monitoring systemic risks, both at the micro and macro level.

    Pre-trade Transparency

    • Pre-trade transparency in equity markets mandates the public disclosure of current bid and offer prices, along with the depth of trading interests at advertised prices, even in the absence of completed trades.

    Market Data Provision and Consolidated Tape

    • There are different data publication formats for markets and national competent authorities (NCAs) according to the specific data type.
    • The provision of market data and the development of a consolidated tape are crucial for ensuring market efficiency and transparency.

    Approved Publication Arrangements (APAs)

    • APAs are authorized entities responsible for publishing trade reports on behalf of investment firms.
    • APAs aim to enhance the quality of trade reporting, particularly for OTC equity trades, and facilitate data consolidation with other trading venues.
    • Investment firms can report to multiple APAs, while operators of trading venues can act as APAs, reporting various types of data.

    Approved Publication Arrangements (APAs) (for info)

    • APAs have stringent organizational requirements including addressing conflicts of interest, non-discriminatory treatment of information, and security mechanisms.
    • Data published by APAs must be provided "as close to real time as technically possible", typically within one minute.
    • Technical requirements for APAs include promoting data consolidation by standardizing formats, ensuring granularity and accuracy for timestamps, and incorporating identifiers.
    • APAs must ensure non-discriminatory access to collected information and provide disaggregated data for analysis.

    Direct Electronic Access (DEA)

    • DEA refers to arrangements that enable access to secondary securities markets, providing both investors and intermediaries the ability to submit bids and offers.
    • DEA arrangements can be categorized as either sponsored access (SA) or direct market access (DMA) depending on the level of access.
    • Investors and intermediaries can participate in trading platforms through various access methods, including membership, membership fees, and execution fees.
    • The diagram illustrates a simplified representation of the various access methods and trading platforms involved in DEA arrangements in secondary securities markets based on investor bids and offers.
