Can you explain how HFT caused a shorter fiber route across the Atlantic? Is this route open to the non-HFT public?
I read Flash Boys and am aware of a custom fiber link between Weehauken, NJ and Chicago, IL, but I thought they are were moving to microwave. I thought there were some HFT links (fiber or microwave) within Europe.
- hermitdev 8y agoMicrowave is great for latency, but the bandwidth sucks. When you need bandwidth & low latency, you need a more direct fiber link.
- Iem3ohvi 8y agoI recall a new transatlantic cable constructed a few years ago being advertised as shaving off a few milliseconds. Trading and cloud providers were mentioned as target customers. I don't know whether they also route public internet traffic.
- daddylonglegs 8y agoThere are microwave links across Europe: https://sniperinmahwah.wordpress.com/2016/01/26/hft-in-the-banana-land/ https://sniperinmahwah.wordpress.com/2016/01/26/hft-in-the-b... There are apparently shortwave links across the Atlantic: https://sniperinmahwah.wordpress.com/2018/05/07/shortwave-trading-part-i-the-west-chicago-tower-mystery/ https://sniperinmahwah.wordpress.com/2018/05/07/shortwave-tr... https://sniperinmahwah.wordpress.com/2018/07/16/shortwave-trading-part-iv-sleuthing-examples-research-tools-techniques-deputies-wanted/ https://sniperinmahwah.wordpress.com/2018/07/16/shortwave-tr... These should have a lower latency than fibre links although the shortwave link will probably have rather a low data rate.
