It appears to me that they automate or in their language ‘contract’ a lot of things we still do manually. Not that it is a bad thing in these early days of discovery and learning how to hold a peg but we need to find a way to be able to automate too when the rules are becoming more clear, which I think we are nearing. Lacking automation will get in the way of scaling up or balloon costs.
Re SDR datafeed, maybe we need to build a crowd sourcing datafeed where a number of people are incentivized to vote for the actual feed values every day after the official feed is updated.
Or just skim this page: https://www.imf.org/external/np/fin/data/rms_five.aspx. They also publish a rates file which can be used to source a feed.
