PERF: Optimize session close lookups in resample bar reader ( #1749 )
...
Optimize session close lookups in MinuteResampleSessionBarReader:
- Adds `session_closes_in_range` method (along with
`session_opens_in_range`) to TradingCalendar to allow vectorized
retrieval of all values in a range of sessions.
- Improves code path for resampling a single session's worth of data (as
is the case when calling `get_value`), since we don't actually need to
look up the close minute.

When retrieving the open and close for a given session, we only care

is significantly faster.

PERF: Avoid repeated recursive calls when getting forward-filled close

Instead of recursively calling `DailyHistoryAggregator.closes` until we
find a non-nan close, we can instead call `load_raw_arrays` once, and
find the value from the returned array.

Should be no functional change.
By making the raise on `if not isinstance` instead of doing a continue on `if
isinstance` (with a raise at the end of the loop if no 'good' conditions were
met'), the function should be more amenable to adding an additional validity
check, after the type check passes.
This is on the path to adding an additional validity checks parameter to
`check_parameters`, e.g. adding an 'is positive' check.

MAINT: Clear up naming and logic in resample close.
...
- Instead of maintaining a separate `j` value, set the bounds of the range so
that `i` is the values emitted by the range.
- Change `close_loc` to `prev_close_loc` since the market close location is used
to ensure that the data index stops at the market open if the entire day is
nans.
- Change the setting of `loc` to be done before the loop which check for nans,
instead of setting to the previous close loc at the end of the loop.
This prepares for a separate fix to prevent out of bounds access when the first
session has nans for all minutes.

ENH: Allow override of order amount rounding. ( #1722 )
...
* ENH: Use regular rounding to calculate order amounts.
We previously tried to prevent accidental over-ordering by truncating
orders down unless they were within 1e-4 of the next higher integer.
Unfortunately, this makes it easy for a sell order to be one share short
of the desired position.
Using regular rounding treats both buys and sells in the same way.
* ENH keep non-rounding behavior consistent, but leave code structured to make easier to override
* DOC make round_order public and describe behavior in docstring
