What is Chi-X and how does it work?

[Updated in February 2019]

Chi-X Australia (CXA) has come a long way since its launch in October 2011. As Australia's first alternative trading venue to the ASX, the exchange began with as little as 6 tradeable stocks to now offering the full suite of 2,100 ASX-listed companies and full suite of 230 ETFs, as well as quoting its own Warrants market. 

In October 2018 Chi-X launched the first tranche of its long-awaited Transferable Custody Receipts (TraCRs), providing investors access to invest in the top US stocks (e.g. APPLE) just like a share which is traded, cleared and settled in Australian dollars (AUD), under Australian regulation, during Australian trading hours. Learn more about TraCRs.

Today Chi-X Australia has over 20% market share, trades over a billion $AUD per day in cash equities and has as much as 30% of the total volume of some big cap stocks such as Telstra and 30-40% of A-REITs (Australian real estate investment trusts). See this weeks most traded stocks at chi-x.com.au or the Fidessa Fragulation Index.

While all this is great, I thought it was time to get back to basics about what Chi-X actually is and how it works. Since OpenMarkets became a participant of Chi-X back in 2015, I've had a number of people ask how it's possible to trade ASX listed stocks on anything other than the ASX and why you would?

So let's get back to basics...

What is Chi-X?

Chi-X Asia Pacific is an alternative market operator and a provider of innovative market solutions

that competes with primary exchanges. It pioneered the introduction of new and competing trading venues in Australia, Canada* and Japan, and previously in Europe (now operating as BATS Chi-X Europe).  *News Flash this morning: Nasdaq acquires Chi-X Canada

In Australia we have Chi-X Australia, a competing stock exchange to the Australian Securities Exchange (ASX) and alternative venue where you can trade the full suite of 2,100 ASX listed companies.  Being a stock exchange, Chi-X has developed new products of their own such as a new Warrants market and most recently with TraCRs See TraCRs – a new world of investment opportunities. Check out CEO Vic Jokovic explaining What Chi-X TraCRs are in the video below.

Check out John Fildes explaining What is Chi-X in the video below.

Chi-X is to ASX like what WoolWorths is to Coles

It's similar to deciding which supermarket you want to buy a jar of Vegemite from, but in our case we're buying stocks.

If your broker is connected to Chi-X, you have the choice to buy your stocks (or place your order) on either ASX or Chi-X, where the end product (the parcel of holdings) is exactly the same.

All other ASX listed products (ASX Warrants, LICs, XTBs etc)                                                     


Chi-X trades can be sold on ASX, and vica versa

Since Clearing and Settlement is still facilitated by the ASX, any stocks you buy through Chi-X will settle on your CHESS HIN or directly with the share registries.  This means you can sell the stock back through either exchange. 

Why trade through Chi-X?

It has an 'Integrated Order Book' at no extra cost

Unlike the ASX, Chi-X has an "integrated order book", which means its 'lit' and 'dark' markets work together. So when you place a trade on Chi-X, the trade will look at both its lit and dark markets (Mid-Point) to fill your trades.
It is often in the dark market(s)* that traders can uncover hidden liquidity i.e. more shares, at a fraction-of-a-cent cheaper price than what's showing in the visible market depth. This is particularly relevant for day traders or high-volume traders, where a fraction of a cent can result in significant cost savings.


Compared to when you place a trade on the ASX, it will only look for fills in their lit market (ASX Trade Match). To benefit from ASX's own dark market (Centre Point), you have to put your trade on separately, providing your broker is connected to Centre Point, and it'll cost you more. (Or at least, ASX charged us brokers more for that transaction.
In saying that, a trading platform that has a Smart Order Router like IRESS and shortly, Pulse, will allow you to have the best of both worlds. It will actually scan both ASX and Chi-X lit and dark markets in the blink of an eye - looking for the best price and fills across all markets.

It costs less to trade

For us brokers, the cost of execution on Chi-X is lower:

  • Limit Order:  0.06bps (passive ) or 0.12bps (aggressive) per trade compared to ASX’s 0.15bps
  • ASX charge for Centre Point0.50bps per trade, whereas Chi-X doesn't charge extra for accessing its Mid Point market


It offers 'price improvement' opportunities

Because of Chi-X's integrated order book, trades can often be executed at a better price for both buyer and seller.  For example, if you put a limit order on Chi-X. it'll check its Mid-Point market (dark market) to see if it can get a better price for you (referred to as trading 'within the spread').  These price improvement opportunities, though often individually miniscule, mount up particularly for active traders. 

Chi-X claims to have already saved investors more than 30 million dollars this year through price improvement opportunities.

It has shorter queue times due to its 'day only' system

Particularly among the heavily traded stocks, making your way through the order queue can sometimes cause costly delays.  In busy periods, it can take up to 20 minutes for orders to reach the front of the order queue on the ASX.  The problem is far less pronounced on Chi-X with its day-only system meaning no orders rest overnight, so all stocks open at 10am allowing for queue priority daily, promoting faster execution.

It has a "Market on Close" order type that extends trading by 8 minutes

Chi-X has introduced a unique order type called Market on Close (MOC) which allows you to trade 8 minutes after normal market hours. Dark up to 4.12 and dark or lit up until 4.20. Watch John Fildes explain MOC

How to trade on Chi-X

Although most online brokers are connected to Chi-X not every trading platform they offer is, so you'll need to do your homework.  Here's a short list of brokers suited for retail traders that are connected to Chi-X.

If your broker platform is connected to Chi-X, you'll be able to select the market in the Order Pad.

Or alternatively if you have access to smart order router (SOR) capabilities, you could select that destination and your trade could potentially get filled across multiple markets - Chi-X, Mid-Point, ASX TradeMatch, Centre Point.  The purpose of an SOR is that it will automatically scan across all available markets looking for the best price.


Where to next for Chi-X?

[updated Feb 2019)

Access to US stocks via Transferable Custody Receipts (TraCRs)

Chi-X has launched in October 2018 Transferable Custody Receipts (TraCRs) (pronounced 'Tracers'). TraCRs can be traded just like a share on Chi-X. They are based on a underlying asset that is a member of the primary index of a specified offshore market such as NASDAQ and NYSE, providing Australian investors with access to invest in the top US stocks with settlement via ASX CHESS - meaning you can hold it on your HIN just like a share.  See more here.


Introducing competition in trading venues is good for financial markets and the global trading community. It challenges the monopoly of the primary exchanges in that country, exposing any excessive costs and lowering them. It promotes fairness and transparency in the way it is regulated, but most of all it encourages innovation.

Chi-X's launch seven years ago not only prompted the halving of trading fees but also widespread trading infrastructure upgrades, lower latency and the introduction of new 'dark markets' such as Mid-Point and consequently, ASX's Centre Point.

This competition has done a great service to our stockbroking industry, benefiting not just the big instos but retail traders too.

I'm looking forward to seeing what Chi-X continues to do over the next few years!
