I have account and data subscription with IB, and I run your scripts Heatmap and MVO, can I simple change "assetHistory(Names[N],FROM_YAHOO)" to "assetHistory(Names[N],FROM_IB)"? Would it work?

Is your code a seperate script I should run before I run other scripts? If so, should I run it every time before I run others? or I should put it somewhere in your Heatmap and MVO script?

Can I get stocks data from Google?
