Being a member of a major commodity exchange for over 25 years I know a thing or two about data. One thing is for sure, I would NEVER rely on Yahoo for my data. They may do somethings great but commodity data is not one of them. I have corresponded with Todd,the developer of this app, multiple times about the need for cleaner data to no avail. As another reviewer noted the currency decimals are off, the bonds and notes are cash quotes, the dollar index doesnt even update etc etc. Its a shame because the app has great potential. It does many things very well and with the addition of user defined charts it would be a homerun. However DATA is the key to it all.(GIGO). I have recomended alternative data providers to no avail, so far. I would certainly pay more for an app that can provide me with clean , usable data. All the major exchanges provide their delayed data for free or a small nominal fee. Its just a matter of doing your homework to find a secondary provider that does the job well, yahoo is not one of them.
I hope All those who understand what Im talking about keep the pressure on the developers to address this major issue.
