http://www.zerohedge.com/news/2015-...e-hft-firm-virtu-has-lost-money-once-1485-tra What does the technical architecture look like software and hardware? The Ex Head Trader now works for a different HFT company and they have a career page discussing what hardware and software they use. https://careers-gtsx.icims.com/jobs...eedsRedirect=false&jan1offset=0&jun1offset=60 What do you think their structure is ? What's a individual small scale version of this do you think? Not trying to trade like HFT but speed is important.
There really isn't a small scale of something like what Virtu is doing. As you decrease the amount of money in the trading account, the infrastructure budget, and the people behind those algorithms, you are left with something that won't perform anywhere close to what they are doing. There are smaller HFT shops that are able to make it with fewer people and resources, but even they, don't achieve the same results. Consistently at least.
HFT is dead since at least 3 years: "How the Robots Lost: High-Frequency Trading's Rise and Fall", By Matthew Philips June 06, 2013 : http://www.bloomberg.com/bw/article...ts-lost-high-frequency-tradings-rise-and-fall Some losers are still promoting HFT... ;-)
I don't know whether this is true maybe to some extent....but this is a result of developing automated trading system by someone who does not thoroughly understand how market works. Among human traders, 95% are losers. Same with HFT, presumably only 5 % of HFT developers thoroughly understand how market works. Just because you carry a Samurai's sword, does not mean you have become a Samourai.
Of the said 95% maybe again about 95% cannot be classified as traders or investors, because they are hopefully undercapitalised with their little accounts of size 2k, 5k or even 10k...
