Which online stock trading company is the best?

Question

which one do you prefer and how much does it cost?

Answer 1

All major brokerage firms provide their clients with on-line services, including trading platforms, latest market & financial news and research.

Customer need to select the site that is best for them.  Traders have requirements in a site, while investors have other requirements.  

Although most sites are geared to general securities and commodities, however customers may have special needs for the types of products they trade, and the markets in which they trade.

Most professional investors and/or traders do not cost one of their primary concerns for selecting a brokerage firm to place their account. It's more important to select a firm with good order routing, and existing order flow, direct exchange membership with their own floor operation and participates in selling groups.

It seems that the most popular firms for on-line investing all of which provide excellent platforms and services are; Scottrade; Chas.Schwab; TDAmeritrade; Fidelity; E-Trade and Thinkorswim

Answer 2

Fidelity.com.  It is one I have used for years.  I pay 10.95 per trade and make few trades per year.  I have seen cheaper rates if you make many trades.
