The comments beneath your reference article relating to HFT at #msg-27098180 are as interesting as the piece itself. Was the entry below submitted by someone you know? ;)Snip: Angry West Coast Canuck 2:11 AM on January 16, 2011 Is this what capitalism has devolved to? In what way does the trading of stocks in this way benefit the corporation whose stock is being traded? In other words, why in hell should a corporation trash its long term prospects in order to bring short term "shareholder value" when those "shareholders" aren't actually interested in the company. At all. The system is very, very broken. I have a feeling it's going to get much more broken before anything gets done to fix it. If anything. -- As I'm sure you are well aware, if you go back to the July 2010 time frame in this forum you'll come across a number of earlier discussions between us, some including poster aladin and others, that delved into the need for and issues related to some means of propagation delay equalization. This is not a new phenomenon to telecoms engineering types. Envelope delay equalization (compensating for the frequency-variability of phase shift along a conductor, called the "phase shift characteristic" and its derivatives, not to mention absolute delays) has been an area of pursuit that transmission engineers have been grappling with since the late 1800s. In fact, it's one of the parameters that affected audio fidelity (frequency slope response) on long copper loops, necessitating the use of "loading coils" along the length of a copper pair, which introduced inductive reactance every 3000 to 6000 feet on lines exceeding 12,000 ft. This was done to offset the innate capacitance between the two conductors of a copper pair. Whether stock traders can be corralled and then be expected to act like copper wires or fibers or radio waves is another problem entirely. FAC ------
