Signals

from qtradex import Buy, Sell, Thresholds, Hold

`Buy`

Buy(
    price: float = None,      # Execution price override
    maxvolume: float = inf,   # Volume cap
    reason: str = None        # Optional label for trade history
)

Long entry signal. is_override = True — executes as a market order immediately.

Attribute	Type	Description
`price`	`float \| None`	Fill price override (default: market price)
`maxvolume`	`float`	Volume cap
`reason`	`str \| None`	Optional label
`unix`	`int`	Timestamp (engine fills on execution)
`profit`	`float`	Profit (engine fills)
`is_override`	`bool`	Always `True` — market order

`Sell`

Sell(
    price: float = None,
    maxvolume: float = inf,
    reason: str = None
)

Short entry or long-exit signal. Same structure as Buy. Market order.

`Thresholds`

Thresholds(
    buying: float,          # Price to buy if not in position
    selling: float,         # Price to sell if in position
    maxvolume: float = inf  # Maximum order volume
)

A limit-order signal. Doesn't execute immediately — the engine watches the market and converts it to a Buy or Sell when the price crosses a threshold:

If the wallet holds currency (not in position): waits for low < buying, then places a Buy limit at buying.
If the wallet holds asset (in position): waits for high > selling, then places a Sell limit at selling.

In live mode this becomes two simultaneous limit orders — a straddle around the current price.

Attribute	Type	Description
`buying`	`float`	Entry threshold price
`selling`	`float`	Exit threshold price
`maxvolume`	`float`	Volume cap
`price`	`None`	Not set by constructor (engine fills from execution)
`unix`	`int`	Timestamp (engine fills on placement)

`Hold`

Hold()

Neutral signal. Prevents execution hooks from triggering but lets them know the strategy evaluated. In live mode this cancels all open orders.
