Cost Above All
The single simplest and best argument in favor of using online brokers, however, is a simple matter of cost. Sometimes it can prove difficult to compare online brokers on fees and other expenses, because these can depend heavily on the fine print. But on the whole, it is usually safe to assume that an online broker will offer significantly lower costs than a traditional broker, simply because they are offering less extensive personal services.
There are a number of other positives as well, ranging from ready access to personal records to rapid trade execution. Ultimately, however, all of these advantages depend entirely upon how comfortable you feel as an investor operating largely on your own.
