How to find out the last EUR conversion rate update?

[pxstein]

Electrum automatically converts all bitcoins in my wallet to corresponding EUR value in a separate column.
Sometimes I suspect that the conversion rate seems not the most recent one.

How can I find out the last EUR-BTC rate update date+time?
From which server/source is the rate retrieved?

Where can I find the (virtual) EUR sum of all my BitCoins?
Read the sum of a all filled 7 addresses

EDIT: Okay since you edited your post.

The rates can be retrieved from different sources (CoinGecko, Kraken, etc.) you can change that from Tools -> Preferences -> Fiat -> Source.

I think these variables are what control how often the price is fetched (someone corrects me if I'm wrong):

SPOT_RATE_REFRESH_TARGET = 150      # approx. every 2.5 minutes, try to refresh spot price
SPOT_RATE_CLOSE_TO_STALE = 450      # try harder to fetch an update if price is getting old
SPOT_RATE_EXPIRY = 600              # spot price becomes stale after 10 minutes -> we no longer show/use it

It does not take so long, just a few couples of minutes as pointed out by OmegaStarScream

Specifically for the EUR - itBit, Kraken, BitcoinVenezuela, coindesk, Bitstamp

Just look at the bottom left of the window of your electrum wallet, next to the green dot

Thank you.

But where do I change these values?
I cannot find them in electrum_data\config   file

I am using the portable version of Electrum

@pxstein, is there a special reason why you want to change these values? I personally not sure that this can be done (maybe it is possible), but if I want to know roughly how much some amount of BTC is worth, I simply visit some of the websites that have long been known as places for reference values of BTC in various currencies.

Our member @bitmover has his own website where you can always see the value of BTC in $ or EUR, and many other currencies.

I don't believe you can change those values by using the configuration file, you probably need to change the source code and recompile the file yourself.

What is it that you're trying to achieve though? as suggested above, you can always get the BTC value from your Electrum, and then head to preev.com to check.

Thanks for mentioning my project.

You can also use this API which can convert any amount of bitcoin to any local currency and use it in the forum.

For example 0.1 BTC in EUR

Code:

They are baked in to the Python source, which you cannot access from the Windows EXEs since Python code is compiled down during the build process. But if you run Electrum directly from the Python interpreter, there should be files littered in your Python's site-packages folder, and these contain the full source code of all Python packages including Electrum, which you can even modify (although be advised that any changes you make will be overwritten on the next update).

Alternative of preev.com, we have https://preev.net/. Preev.com had problems, back to normal bit eventually it was dead months ago.

One more https://pnnv.com/?datasource=bitstamp&btc=btc&val=1&currency=eur that has an announcement thread
