RE: 2) use a VPN block (e.g. Express VPN)
As a suggestion (and I haven’t tried/tested this myself), for those that use a VPS i.e. Speedy Trading Server, which is hosted in the US. You might be able to update your Share Trade Tracker via your VPS. I.e. install Excel on your VPS and load your Share Trade Tracker from your VPS, that way your using a US Geo IP Address, which then may allow you to update prices from Google/Yahoo etc.
Once again, I haven’t tried this myself, but it might work. Worth a try anyway.
