<div>Latency issues are more than just the fiber, but the infrastructure too. There’s a decent whitepaper (we wrote, sorry for the plug) around FIX at</div>

<div>—excerpt —</div>
<div><br>
</div>
<div>
<div>The FIX Protocol specification was co-authored in 1992 by Robert Lamoureux and Chris Morstatt, specifically to support electronic communication of equity trading data between Fidelity Investments and Salomon Brothers, for pre-trade and trade activities.
Since its initial release, the scope of FIX has expanded significantly, through to the post-trade space, supporting straight-through processing (STP) from indications of interest (IOI) to allocations and confirmations. FIX is now the de facto messaging standard
for pre-trade and trade messaging in global equity markets, and has been adopted more broadly in post-trade activities, foreign exchange (FX), fixed income and derivatives.</div>
<div><br>
</div>
<div>Who Uses FIX and Why?</div>
<div><br>
</div>
<div>There are a number of key reasons why the securities community continues to use, develop and invest in FIX infrastructure, including:</div>
<div><br>
</div>
<div>• FIX is a free and open standard.</div>
<div>• FIX is not generic. It was developed by the securities community for securities applications, and is extensively used, tested and peer reviewed to ensure it remains fit for purpose.</div>
<div>• The FIX protocol is relatively simple and has a fairly narrow focus; key benefits being very little overhead and improved protocol efficiency and performance over a generic messaging scheme.</div>
<div>• FIX compresses the time needed for price discovery and time to transact, by enabling the electronic exchange of trade-related information (it does not require human intervention).</div>
<div>• Since FIX enables the electronic exchange of trade-related information, it is a key component in automation for high-frequency trading, algorithmic trading and arbitrage (we discuss these shortly).</div>

The thing that stuck out to me most - is the updates via multiple 'exchanges' when an order is placed, and the front-running they described. Obviously as network builders it is not our role to take ethics and morals into account when doing things like this
- but with the structure of ASX, is the same thing [frontrunning] possible? Or is this industry secret/question that won't be answered?<br>
<br>
I understand and fully support the need to have low-latency communication with the ASX to catch trends first and get your orders filled at the right price, but the idea that they were detecting trades early and beating them to the trade before the order was
filled is outright devious (IMHO).<br>
<br>
Ethics and the actual trading itself aside - i liked the idea of staggering the orders so they hit out at once, and the new exchange they started using a 60km roll of fibre to artificially inflate response !

<br>
Hi list,<br>
<br>
Just watched this piece:<br>
<br>
<a href="http://www.youtube.com/watch?v=8RFLIj4a2kw#t=29" target="_blank">http://www.youtube.com/watch?<u></u>v=8RFLIj4a2kw#t=29</a><br>
<br>
It's 60 minutes, so a bit sensationalised, but it discusses the role of fibre optic networks in stock exchanges and namely High Frequency trading, and some interesting solutions to the problem. Found it quite interesting so thought I'd share!<br>
<br>
Thanks<br>
<br>
