So what you are saying is that a recent COIN amendment makes a change which makes it compliant with one of these SEC rule changes related to BATS released in the middle of the night?
As in COIN was not compliant with this new rule prior to the recent amendments they made?
The last time COIN amended their S-1 was 2/8/17 (http://www.nasdaq.com/symbol/coin/sec-filings). This most recent approved rule change was proposed by BATS, the exchange that will trade COIN. They amended their own rules, which are approved by the SEC, in the ways I described above.
