I set a stop 4 points down on the Russell 2000, and if it hit 66, it would close out 60 small cap positions. Day's low was 68. I got up at 8 and all my position had been sold. I looked at a very odd tick on the graph. Other than blatent stop running, it seems like a fair and orderly market would not allow a quick 4 point dip. A few seconds later, it was back to 68. Anyone know the best way to investigate this ?
