Fil Mackay wrote a new blog post titled Sponsored Access: feathering the nest of a Black Swan?
Market Access Mechanisms Over time the equities marketplace has evolved from phone-based trade execution, to using computerised channels such as Direct Market Access. Direct Market Access This is where a trader sends an order electronically to their broker who, assuming everything is OK, simply passes it straight through to the market. Unlike in the past, where the trader may have placed an order with the broker, granting them some discretion over when and how to execute it; DMA is simply a pipe giving you immediate access to the market. Think of it as a no-frills self-service offering. Naked...

Fil Mackay wrote a new blog post titled A New Model for Understanding High Frequency Trading
I have found the term High Frequency Trading to be somewhat overloaded, and now unusable term. Instead of referring to high-tech traders, the terms is now referring to more traditional traders who are dragged into the technology war in order to protect themselves. To throw both of these groups under the one "HFT" label is to completely misunderstand what is going on. I would like to propose a model for HFT that splits the term into 4 subcategories: Components of HFT: Market Making: automated quoting of prices in order to earn the bid/ask spread Algorithmic Execution: automated and...

Fil Mackay wrote a new blog post titled Chi-X Australia take off?
With the expiry of ASIC's transitional arrangements for best execution I think the dynamics of the Australian cash equities market is about to shift dramatically. Thus far, Chi-X AU as been trapped in the first phase of liquidity capture: market makers being the predominant quoter of resting orders on the venue. While other brokers have been taking better prices when available, they predominantly quote on ASX. The key barrier to Chi-X at this point is the reluctance for brokers to quote orders on Chi-X in preference to ASX. This motivation is understandable - up until now not all brokers have...

Fil Mackay wrote a new blog post titled New Age TCA
A few interesting articles on Tabb Forum this week about TCA. Couldn't have said it better myself Larry! I have developed a "high frequency TCA" technology that assists buy-side firms (and by extension sell-side) to see deeper inside their execution processes. While traditional TCA takes an aggregate approach to evaluating the performance of execution, HF-TCA aims to also inspect what happens to each child order once it is sent for execution. But liquidity is liquidity, right? If you look at child orders, some will win (meaning the price moves favorably after the fill) and some...

Fil Mackay wrote a new blog post titled AFR: Call for tax that already exists?
Keeping up the momentum, the AFR posted this article on "Call for tax to rein in high-speed trading". Unfortunately for the title, it's already in effect. This article is based on a pretty good report from Baseline Capital. FSC chief executive John Brogden rejected any suggestion of an outright ban on high-speed trading of shares, but said regulators needed to keep a tight rein on the sector to prevent market manipulation and negative consequences for investors. “Both dark pools and high-frequency trading have a legitimate role to play in the market and as such we reject any calls...

Fil Mackay wrote a new blog post titled AFR: Pay up, high-frequency traders told
The AFR ran an article on HFT, purporting to report on an increased desire to push more supervision costs onto HFT. The central tennant of the article does not make sense, and perhaps by extension the Treasury report it's based on. A substantial increase in algorithmic trading including HFT [high-frequency trading] – incorporating not only increased trading volume but increased cancelled orders and messages for each transaction executed – has led to a general increase in ASIC’s workload, The terms are a bit muddled here - there are two items that ASIC charges the supervision levy.

Fil Mackay wrote a new blog post titled AFR: A little transparency would go a long way
Adele Furguson wrote a not-bad piece on the removal of broker ID's from the Australian equities market back in 2005. One aspect of the story she didn't mention was the fact that pre-2005 only brokers could see the ID's (at least in theory). This created information asymmetry, which the brokers did not mind, since their clients would need to constantly ring them to find out the identity of orders they were interested in. Fixing this gap was certainly a positive. At the time I rallied against the "large investment bank" push to ban real-time ID's. But I appreciated the fact that they...

Fil Mackay wrote a new blog post titled The NBN of Liquidity
Previously I have proposed TimeMatch, a system where every order is auctioned in a timeframe that the order's owner chooses. This would mitigate the speed advantages enjoyed by the technology firms. It basically means that investors get to choose, when they place an order, how much they value speed of execution verses improved prices. They are not forced to value speed of execution over improved prices, as the current price-time priority rules say. Let's look at another thought experiment: a market modelled on the NBN. National Broadband Network To those not in Australia, the NBN is a new...

Fil Mackay wrote a new blog post titled The Aus: HFT an unlevel playing field?
Andrew Main wrote a piece in The Aus on HFT, interviewing Zac May the author of the Industry Super Network ASIC consultation paper response I responded to earlier. Zac May says: High Frequency Trading is the creation and then the exploitation of an unlevel playing field HFT certainly didn't create the market we currently have. It is human intuition that said that the guy that matches the order first gets the trade (price-time priority). HFT's have just become the most efficient at adapting to the market that already existed. Maybe Zac is talking about quote stuffing (in the US - it doesn't...

Fil Mackay wrote a new blog post titled Fears about HFT dislocated from reality
Gareth Hutchens posted this followup to the weekend article. Lets look at the weekend article first: Not everyone thinks so. Some sections of the financial industry are privately seething that Funke Kupper and others have been whipping up hysteria about high-speed trading. In the bars of Sydney's financial district, the topic is waved away with scorn. ''It's just become a scapegoat,'' is the refrain. Funke Kupper is both responding to concerns in the public about HFT, and at the same time helping to further those concerns. He is in a difficult position. On the one hand you have people...

Fil Mackay wrote a new blog post titled HFT debate: talk your own book
There has been some interesting discussion on HFT from significant players in the ASX broking community. Firstly, UBS got into the debate by calling on HFT to be curbed: “There are some things that we support which aren’t necessarily great for our business, but we think they are actually right for the market structure,” UBS is implying that HFT is good for their business, but they'll play the honesty card and admit it's not great for the market as a whole. I'd say their share of HFT business is somewhat underweight, and therefore see a competitive advantage in laying into HFT in the hope...

Fil Mackay wrote a new blog post titled The HFT Stole My Lunch Money
Perspective When talking about HFT, it’s important we get this problem in perspective: predatory HFT is not to blame for taking that stock you bought for $2, ending up at 20c a few months later. I was reminded of this by a mate (who knows retail traders very well) who said HFT is a long way from the biggest problem faced by retail traders. Lack of knowledge and information that comes through established private networks would be higher on this list. Predatory HFT is akin to a “rounding” loss for retail traders, and only directly exposes you when you trade, not hold, securities. Nonetheless, a...
