Order Properties

The CoinbaseBrokerageModel supports custom order properties. The following table describes the members of the CoinbaseOrderProperties object that you can set to customize order execution:

TimeInForcetime_in_forceA TimeInForce instruction to apply to the order. The GoodTilCanceled TimeInForce is supported.
PostOnlypost_onlyA flag that signals the order must only add liquidity to the order book and not take liquidity from the order book. If part of the order results in taking liquidity rather than providing liquidity, the order is rejected without any part of it being filled.
public override void Initialize()
    // Set the default order properties
    DefaultOrderProperties = new CoinbaseOrderProperties
        TimeInForce = TimeInForce.GoodTilCanceled,
        PostOnly = false

public override void OnData(Slice slice)
    // Use default order order properties
    LimitOrder(_symbol, quantity, limitPrice);
    // Override the default order properties
    LimitOrder(_symbol, quantity, limitPrice, 
               orderProperties: new CoinbaseOrderProperties
                   TimeInForce = TimeInForce.GoodTilCanceled,
                   PostOnly = true
def initialize(self) -> None:
    # Set the default order properties
    self.default_order_properties = CoinbaseOrderProperties()
    self.default_order_properties.time_in_force = TimeInForce.GOOD_TIL_CANCELED
    self.default_order_properties.post_only = False

def on_data(self, slice: Slice) -> None:
    # Use default order order properties
    self.limit_order(self._symbol, quantity, limit_price)
    # Override the default order properties
    order_properties = CoinbaseOrderProperties()
    order_properties.time_in_force = TimeInForce.GOOD_TIL_CANCELED
    order_properties.post_only = True
    self.limit_order(self._symbol, quantity, limit_price, order_properties=order_properties)
