Online Broker Survey

.

The more than 2,400 readers who filled out our online questionnaire in August and September report that Web site reliability is getting better. A vast majority of them feel they're treated fairly when the dreaded margin call arrives.

Still, survey participants had plenty of complaints to share -- bad executions, high costs, poorly trained customer reps and accounting snafus, to name a few. And nearly one in four say they're thinking of changing brokers in the next six months, so brokers still have their work cut out for them.
