unrecorded trade?

[Walter Crompton]

How can it be that an automatic trade occurred at below the level of the lowest point of the trade quote in that hour? in other words, a position I held automatically sold at well below the lowest point of the whisker during that hour. Do the whiskers sometimes not extend to the true extremes?  It was a very sudden and very short-lived drop, and I smell a rat.
