Baron, It means that for a 2 minute period, you can do as many trades in that stock in the same direction for 1 ticket price. So you can buy 2k csco, buy another 2k up .02. then sell them all up a dime, and then buy another 2k when it retraces a nickle, and sell that again. If it's all done in under 2 mins, it's all for just 2 tickets. 1 buy, and one sell, even though you technically did 2 roundtrip trades, and actually 3 buys.
