Problem Statement:
On non-trade dats, get_trade_time() returned the second-to-last trade instead of the latest one.
Root Cause:
_pick_trade_date(trade_dates,use_today=False) skips trade_dates[0], but on non-trade days trade_dates[0] is already the most recent trade date
Solution:
for non-trade days, put use_today=Ture
