If you are a day, swing, or momentum trader, how would you trade in this market? Did trading on May 6th blow through all the sell stops on the order books?
Well, I have one friend who is an accomplished trader and he related his strategy regarding this issue. He refrains from trading if the market moves too violently or if there isn’t a clear reason for the market movement (e.g. a war, terrorist attack, major corporate bankruptcy, etc.)
One supposed benefit of an electronic marketplace and program trading by black box algorithms (algos) is market liquidity that would prevent just this type of collapse. The October 19th 1987 Black Monday crash was supposedly caused by computer program trading. It happened again this time — did we learn anything?
Or, as the saying goes:
History is the same events happening to new people who experience it for the first time as though it never happened before.
