I did have the scanner running on Friday ... DGX was #2 on it at 10:29 AM and then went to #1 for many minutes thereafter ... if you were fast enough you could have made some money ... slow and it would have been a scratch ... very slow and you would have lost a bundle. Let me look at the Twitter feed mentioned in this Bloomberg piece:
Tweet simply conveyed a market rumor, says the author. I'd like to know the time stamp of the deleted tweet ... was it 10:29 AM or earlier?
StockTwits stream from the time... WallStJesus and OptionRunners both noted unusual activity in calls before my scanner picked up stock movement at 10:29 AM.
Nanex posted a nice chart, as usual ... professional traders need a good data feed like his, $9.99 isn't going to cut it.
