I fully understand why the traders would not want any sort of warning to come between them and executing their trades. However, I guess that's just "tough". There needs to be some safe guards to protect the retail traders. It's that from of "greed" that has created a mess on the Street and in our country, to say nothing of the global markets.

Having some years of experience with Wall St software, it is often poorly written because it is always needed yesterday and is rarely well specified or well tested. Thus there are often few common sense error checks built in. The high-speed super-computer trading programs are in constant modification to pick up patterns faster in order to "name that tune with fewer notes". There is little interest in hypothesizing or testing what would happen if there is a totally unruly market or patterns fall into the black swan category. With dozens of these black box programs interacting, the result is chaos. These programs are not designed using standard engineering practice which tries to systematically eliminate modes of failure. If airplanes were designed this way, they would fall out of the sky every time they encountered some untested harmonic turbulence.
