Yes, I noticed data problems as well. ETF's are not updated to show the correct component stocks, or somtimes they don't have any component stocks at all, even though I can verify the ETF components by going to the ETF web site, like the SPDR's etc. The tech support helps on formula creation, but as far as correcting defects and data errors, support is lacking and they have not responded at all. There is some other weirdness in some of their features, and they are a bit defensive in their posture. Its a good product, just wish they would be less arrogant, and more helpful in resolving their issues. Also their iPad program is lacking, and not ready for prime time.
