The Dow has its best day since August 1st but its the NASDARK that takes the biscuit with a 1.4% gain - its best day in 6 weeks. S&P 500 futures ramped all the way to recent highs, snagging stops all the way to its 50DMA once again. Trannies were the big short-squeeze high-beta muppet-killers today though +2%!!

By plotting the number of messages for each of the 6 multicast lines used by the Tape C SIP (Securities Information Processor), we discovered the quote blasts map directly to individual multicast lines. The ‘line’ carrying AAPL’s ticker saw the largest and most egregious quote volumes (spamming perhaps) that eventualy ovehwlemed NASDARK’s creeking infrastructure.
