60k es minis sold seconds into the close today. fat finger trade, or tactical dump/dive to cause the least ripples? $4billion notational, around $250mil margin req., i'm sure i wasn't one of us. whats the rationale behind a trade like this into the close? head fake? first rat off a sinking ship? 'simple', yet rushed, flattening out before the fed meeting? it seemed more than algos working toward their next target, this seemed personal.
