If you are making more than 30 trades a quarter you have access to Pro and MT - both of them have top losers and gainers. Along with that Pro has a scanner that you can customize: The E*TRADE Pro trading platform is available at no additional charge to Pro Elite active trader customers who execute at least 30 stock or options trades during a calendar quarter. To continue receiving access to this platform, you must execute at least 30 stock or options trades by the end of the following calendar quarter.
