whilst all trading is USD based, as you pointed out, however in realities for me, the value in GBP is more understandable/comparable, and as such i use your bitcoin gadget to display my wallet content, and it's value in GBP and then i use your other gadget to display the current GBP exchange rate.
I use the BitPay exchange api because one of the PC accessory sites i use accept bitcoin, and use that site for their conversion rates.
THe high / low rates being in GBP would just have been a nicety
oddly enough nobody does this, even the BitPay widget for your phone, that they make only ever works in USD yet their site is a global concern that supplies exchange rates in multiple currencies.
i guess it just boils down to the fact i'm used to working in GBP, what i pay for with bitcoin is likely to have a comparable GBP value
Well, not a scenario I would have thought of, and officially not supported, but I think it can be done. Use this settings. I might add conversion option in the next version to make this simpler.
Primary exchange:
https://bitpay.com/api/rates/GBPPrimary exchange JSON key: json.rate / conversionRate
Ticker currency: USD
Target currency: GBP
Secondary exchange:
https://www.bitstamp.net/api/ticker/Field 1 JSON label: high
Field 1 JSON key: json.high * conversionRate
Field 2 JSON label: last
Field 2 JSON key: json.last * conversionRate
Field 3 JSON label: low
Field 3 JSON key: json.low * conversionRate
which by chance also shows a second issue, the secondary info does not populate unless the gadget is expanded and left for the update period to complete (i also noticed a similar failure to load automatically on the primary info if you used 2 wallets in gadget)
leaving for the time it took to screenshot and upload resulted in it updating....
I'll look into it - I did notice similar problems with Google Docs. It fires out several requests and waits for responses, and updates as response is received. I think it might not update if response received is not valid. One thing you can do is simply open settings and click OK - this forces an update.
