>>> from rayforce import Table, Column, Vector, Symbol, Time, F64
>>> quotes = Table({

time.fromisoformat("09:00:00.295"),
time.fromisoformat("09:00:00.145"),
time.fromisoformat("09:00:00.155"),
time.fromisoformat("09:00:00.345"),
],
ray_type=Time,
),
"bid": Vector(items=[100.0, 101.0, 102.0, 200.0, 201.0, 202.0], ray_type=F64),
"ask": Vector(items=[110.0, 111.0, 112.0, 210.0, 211.0, 212.0], ray_type=F64),

>>> result = (

first_time=Column("time").first(),
)
.where((Column("bid") >= 110) & (Column("ask") > 100))
.by("symbol")
.execute()
