🚀 Quick Start

>>> from datetime import time
>>> from rayforce import Table, Vector, Symbol, Time, F64
>>> from rayforce.types.table import Column

>>> quotes = Table.from_dict({
        "symbol": Vector(items=["AAPL", "AAPL", "AAPL", "GOOG", "GOOG", "GOOG"], ray_type=Symbol),
        "time": Vector(
            items=[
                time.fromisoformat("09:00:00.095"),
                time.fromisoformat("09:00:00.105"),
                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 = (
        quotes
        .select(
            max_bid=Column("bid").max(),
            min_bid=Column("bid").min(),
            avg_ask=Column("ask").mean(),
            records_count=Column("time").count(),
            first_time=Column("time").first(),
        )
        .where((Column("bid") >= 110) & (Column("ask") > 100))
        .by("symbol")
        .execute()
    )
>>> print(result)
