Unlike the CME. all electronic exchanges a la eurex or euronext (nyse-euronext <g>) have not reported many glitches in fast markets. IMO, these are due to queuing and priority order principles. Also, just an evidence, members with a dedicated dataline to the exchanges we have their transaction committed faster, and faster the faster their connection is. People on non-real-time operating systems will just have to wait a couple of seconds for a possible window to get their trade through. Say, those people (most small orders) would not have a chance to clobber the system as they even won't get in. And that is a lot of orders. <g> When you don't have the tools, don't expect to trade like a pro. ROFL. The other part, harsh moves: I try to verify an hypothesis. The more sophisticated program trading, r-quanted algorythms, trading systems are used, the more they will trend to a mean, resulting in more programs reacting the same way on the same data. The more cutting-edge the programs are, the lesser specialists would be able to write those programs. And a cutting-edge is an edge, concentrated, not diversified theories. This could explain steadily rising markets as well as sudden corrections. FWIW.
