Return an Order.*(...) value from on_tick. Returning nothing holds.

• Order.Hold() — do nothing this tick and keep any open position.
• Order.Close() — flatten the current position at market.
• Order.Buy(...) / Order.Sell(...) — place an order.
• Order.Score(score) — emit a ranking score instead of trading (see below).

Give a quantity and, optionally, a price limit.

• The quantity comes first — positionally or as quantity=.
• A whole number means whole units: quantity=1.
• For a fractional size, use base(...), base_units(...), or as_base(...) — for example quantity=base(0.25).
• limit_price= is optional. Build it with price(...). A literal float is accepted; wrap a computed decimal in price(...).
• A limit_price of 0 or less means market.
• reduce_only=True lets the order only shrink the position, never flip or grow it.
• A quantity of 0 or less holds at runtime.

6            return Order.Buy(base(0.05), limit_price=price(self.cap), reduce_only=False)
7        return Order.Hold()

Order.Score ranks ideas instead of placing a trade directly.

• Pass the score positionally (Order.Score(x)) or as score=x.
• The score is a whole number — wrap a computed decimal in int(...).
