I use MarketSmith and I like nearly everything about the software except charts frequently fail to load and I must wait a minute or more to see any charts. I use an iMac as well as an iPod. I am convinced the problem is not my server because I frequently go to another state with a different ISP using both computers and the problem is always the same. If I want to review the charts late in the trading day before making a trade, the inability of seeing the Marketsmith data has prevented me from making a timely trade. This now seems to be an everyday occurrence, even on weekends and the middle of the night. Frequently, I spend more times waiting for information to download than I actually do studying the info. Also, when using Marketsmith I get far too many pop-up ads because pop-up blockers must be deactivated to use the software. Software of this expense should not serve up ads. A huge frustration. So far, I am living with the problem but if I can find anything better I will switch.
