due to the too short time setting the last proposal is not approved, in this period some suggestive ideas emerged and it seems we need to consider more on the back asset selection.

below is the XCD/USD rate chart in last ten years, we can see that from 2011 the rate is fixed to 0.37037 USD/XCD with some minor fluctuation.



the design logic/purpose of XCD(not bitXCD) is to peg USD, if we create bitXCD which has a fixed rate to bitUSD, it would be great, right?

I tried to set a newly parameter as below after went through all the ideas about it.

MAXIMUM SUPPLY 100,000,000,000
Precision 4
Feed lifetime   1year #to make a 'static' price
Minimum feeds   7
Force settlement delay   10 min #to enable instantly USD/XCD conversion, should be as short as possible
Force settlement offset   0.3%   #with the fixed rate shorters have little risk, so the 'service fee' should be low.
Max force settle vol   5%          # need to be larger than other BTS backed smartcoins
Short backing asset   USD

and, witnesses need to feed as below:

1XCD = 0.37037 USD
MCR:100.1%  #should be higher than but close to 100%
MSSR:100.5% #even when margin call happen, shorters will lose little.

any ideas on this?
and, this solution is not tested yet, is it possible to do the test in several days to ensure it is bug free?

proposal created and is waiting for approval:
https://cryptofresh.com/p/1.10.6006

witnesses please prepare the price feeding for bitXCD, with the assumption that 1USD=2.7XCD.

Great news! I have one concern though. It is not clear from the proposal how decentralized will be your bots. Since you plan to use funding through WP, I would expect the resulting product to belong to community and server nodes to be easy to run by anybody. Btsbots is great, but it was ran in a centralized way, and wee see what happened.  Could you make any comments regarding this concern?

We will not provide servers for the purpose. Everyone has to run the bots on their own computers or servers. Many of the market making strategies are suitable for use on computers that aren't on all the time. So it will create a very redundant swarm of decentralized bots, where everyone holds their own keys, and many their own nodes.

So market making pro's can run this on a server, and normal people plus noobs can do it on a laptop. There will be a CLI version and an installable GUI version.
