SBD Price Feeds with Automatic Peg Support
I am in no position to tell anyone how to run their witnesses, I am merely sharing the strategy I employ for mine.
Since the beginning, I have been running highly reactive price feeds updates (update on 1% change treshold, from near real-time volume weighted market prices).
I used to support the peg by manipulating the base, however, marking the peg support via quote is a much more elegant solution, so as of today, I am switching to that.
Calculating the Quote
We can derive the quote by looking at implied SBD/USD spread, and thus determine how much offset is necessary to create a $1 USD to $1 SBD peg.
Calculating the quote using implied price is actually really simple:
quote = 1 / markets.sbd_usd_implied()
You can find a reference implementation for witness price feeds in Python here.
steemtools support
Steemtools now supports setting the quote via quote argument:
tx = Transactions().witness_feed_publish(current_price, witness_name, active_key, quote=quote, sim_mode=False)
print(tx)
To upgrade to latest version (1.3.3), please run:
pip install -U steemtools
Result
Thanks

UV and RS for you as always.
Interesting. Thank you for sharing :) I have noticed that the peg has strengthened quite a bit over the last several days versus where it was a couple weeks ago when Steem was approaching $.10
