Measuring the latency across the harbour is hardly relevant.</blockquote><div><br>Dare I suggest it, but the fact that this is being put in by Vocus means that there probably is at least someone with money who think it is relevant.<br>

<div><br></div><div><span style>Correct - so where you pull your cable up from the harbour, and the path it takes back into the broader network compared to alternate paths, is completely relevant. You may have a short path across the harbour, but if the cable has to run another 600 meters in an indirect path either side to get back to the nearest joint, it adds latency (not saying this is the case, by the way).</span> </div>

<div><br></div><div>There is some demand for low latency circuits between ASX Gore Hill and Chi-X at Equinix SY1, but as Chi-X currently account for only 2-3% of trading volume in Australia (at the moment anyway) I'm not sure how much demand there will actually be.</div>
</blockquote><div><br>Arbitrage is only part of the equation and as you state not as relevant in the Australian industry at this point in time. In reality, arbitrage can't really be that useful in Australia as the rules state that market orders must be met at the lowest price between Chi-X and ASX anyway.<br>
</div></div></blockquote><div><br></div><div><span style>Agree. hence limited demand for low latency services between ASX and Chi-X. The only real demand at the moment is low latency to the ASX, and those that want that will simply telehouse at the ASX's facility and connect directly to the market. That said, the rules are changing all the time as ASIC get more comfortable with the whole dual market arrangement.</span> </div>
