The avg IBKR trader trades over 600 times a year. The average TRAD trader trades over 400 times per year. The avg ETFC, AMTD, and Schwab trader makes under 30 trades per year. TRAD is the last place to find the kind of high-volume trader suited for the IBKR platform . . . TRAD does about the equivalent of 25% of IBKR volume, which is pretty remarkable for a firm with just $2.5 in client capital (IBKR has about $18 billion in client capital, if I remember correctly). So as far as growth goes, for IBKR it's pretty much TRAD or bust.
