Watch Your Incentives — NASDAQ added two new incentives programs, and robotraders responded. On November 1st, there were 369 seconds where the number of quotes in BAC exceeded 17,000; a total of 6.6 million quotes. During those seconds, only 1,879 trades executed. Between market open (9:30am) and 12:45, BAC had 7.8 million quotes and 116,000 trades. Which means 85% of all BAC quotes occurred in those 369 seconds. Which means it is likely that one algo from one firm (all of this quote spam is from Nasdaq) is responsible for 85% of all canceled orders in BAC. (via Robert O’Brien)
