Our free real-time charts have several important restrictions that may cause you to prefer our ExtraRT or PRO service instead:

• Most stock orders are executed on the NYSE, Nasdaq, or TSX exchanges.  Only our ExtraRT and PRO service shows the "official" data for those exchanges.
• There is no reliable volume information associated with our free real-time data bars.
• Free real-time charts are only available for popular US stocks.  We do not have free real-time data for Canadian stocks or thinly traded US stocks.
