i recenrly added yunbi and make use of the python-bitsharesrpc package also available in bitshares-pytools as a submodule ..
maybe I should start tagging stuff ;)

ok, I've updated to the new version of the script (except the url to bter wasn't correct, so I had to remove the "data." from it).

I really hope I am doing something wrong when calculating theses percentages:

I don't think so, I get similar results:

http://bitsharesblocks.com/delegate/feeds?name=delegate-dev1.btsnow

I added percent devaitions from the median a few days ago.

How come for BTSNOW most feeds are ok .. but not BTC which is of more than 15%???
Is this on purpose?

It's certainly not "on purpose", we're just running one of the available feed scripts (looks like Xeroc's). The only change I see to it is we changed the URL for bter after it went down and came back up. Maybe there's been later changes that we haven't merged in?

I just checked and noticed that the repo has moved from what we initially cloned, and that there are changes at the new repo. Are they any important changes that we should get from there, Xeroc?

pricefeeds are a concern we should reconsider.

we would love to sell bitBTC - BTC on 1:1, but the bitBTC price is always 2% to high, to do it.

Thx, looking into this.

thanks for your feedback ;)

I am just manually updating the feeds ;)

Would you please take a closer look at your delegate feed script. Your numbers
seem a little off:
