ON FEBRUARY 3RD 2010, at 1.26.28 pm, an automated trading system operated by a high-frequency trader (HFT) called Infinium Capital Management malfunctioned. Over the next three seconds it entered 6,767 individual orders to buy light sweet crude oil futures on the New York Mercantile Exchange (NYMEX), which is run by the Chicago Mercantile Exchange (CME). Enough of those orders were filled to send the market jolting upwards.
from the article:
It is certainly true that HFTs are constantly sending and cancelling orders. Some of that activity may be tied to a manipulative technique called âquote-stuffingâ, in which a flood of orders and cancellations causes congestion on networks and thereby a fleeting trading advantage. But the legitimate explanation for it is that marketmakers cannot afford to be static in case the market moves against them, and that in an ever-faster market HFTs have to be quicker to adjust prices.
In this case, the actual value based on the iran news probably $1 move up. With that in mind, who was making all the noise?
My guess is HFTs. Not 1 hft firm, but hundreds of them confusing the market makers on the floor and electronic.
Like I said many times, HFT will blow u away
