You can get the data from hivesql, from the VOFillVestingWithdrawals table.
Here is a query I run once per month to get the data for the previous month ... adjust the dates for whatever period you need:
DECLARE @MonthRange INT = -1;
DECLARE @QueryDay INT = 1;
SELECT
CONVERT(DATE,timestamp) as T_date,
SUM(deposited)/SUM(withdrawn) as HIVEVESTS
FROM VOFillVestingWithdraws
WHERE
CONVERT(DATE,timestamp) BETWEEN DATEADD(MONTH, @MonthRange, GETDATE()-@QueryDay) AND GETDATE()-@QueryDay
AND deposited_symbol = 'HIVE'
GROUP BY CONVERT(DATE,timestamp)
ORDER BY CONVERT(DATE,timestamp) asc
Unsurprisingly, it's still basically a straight line post-split.
Well that makes my work redundant 😅
