Will a stop order get triggered if the floor is hit and trading is halted?
quantycuenta is right, if a halt is in place, then no trading will occur, simple as that. But in the practice of risk management it is a little different. Want to remind you that you are assuming that trading is halted immediately upon the drop in price. That doesn't always happen, so if there is any time between the actual price drop and halt of trading, then it is possible that your order will be filled, depending on how liquid your security is. Also not every security has circuit breakers in place and the exact requirements to trigger a breaker is not public information.  In some cases, trades are ordered to be rolled back (reversed) by the exchange but this is usually reserved for institutional traders who make some sort of mistake.  This article below mentions day traders who bought at or near the bottom of the May 6, 2010 flash crash. This was before circuit breakers but I think it's a good story for someone looking to understand the finer workings of the electronic market.  http://www.marketwatch.com/story/book-takes-a-look-inside-professional-day-traders-1339513989350
