A month here is the trades disclosed in filings made public in it, not the trades made in it: members have up to 45 days to report a trade. Amounts are the ranges the filings disclose; "up to" is the top of a range, and a total adds the tops. Each trade counts once. The President and other executive-branch officials are not counted. Each member's page links every trade to its filing. This is a public record turned into a page, not a recommendation and not a statement about why anyone traded.
