This reverts commit 85c4f66.
Unfortunately, the performance fix for
/trade_aggregationsin 85c4f66 does not work correctly if there are no trades for the requested market, range and resolution within a given limit (i.e. no data in a bucket in a range).As an example, consider a market with no trades on weekends and the following params:
start_time= Monday, 1st day of the month (for simplicity),end_time= Sunday, 14th,resolution= 1 day,limit= 7 days.Before 85c4f66 Horizon returned 7 buckets for each day: Monday-Friday and Monday, Tuesday the following week. With 85c4f66 it returns just 5 buckets because the
end_timewould be overwritten to EOD, Sunday, 7th. This code works great when all buckets in the range are non-empty, however, if there's at least one empty bucket it will return less thanlimitbuckets.
