               };
    LimitOrder(_symbol, quantity, limitPrice, 
               orderProperties: new IndiaOrderProperties(Exchange.BSE, IndiaOrderProperties.IndiaProductType.CNC)
               {
                   TimeInForce = TimeInForce.GoodTilDate,
               };
}
def initialize(self) -> None:
    # Set the default order properties
    self.default_order_properties = IndiaOrderProperties(Exchange.NSE, IndiaOrderProperties.india_product_type.NRML)
    self.default_order_properties.time_in_force = TimeInForce.GOOD_TIL_CANCELED

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 = IndiaOrderProperties(Exchange.BSE, IndiaOrderProperties.india_product_type.MIS)
    order_properties.time_in_force = TimeInForce.DAY
    self.limit_order(self.symbol, quantity, limit_price, order_properties=order_properties)

    order_properties = IndiaOrderProperties(Exchange.BSE, IndiaOrderProperties.india_product_type.CNC)
    order_properties.time_in_force = TimeInForce.GOOD_TIL_DATE
    self.limit_order(self.symbol, quantity, limit_price, order_properties=order_properties)

Updates

The SamcoBrokerageModel supports order updates.

Handling Splits

If you're using raw data normalization and you have active orders with a limit, stop, or trigger price in the market for a US Equity when a stock split occurs, the following properties of your orders automatically adjust to reflect the stock split:

  • Quantity
  • Limit price
  • Stop price
  • Trigger price

Fills

The SamcoBrokerageModel uses the EquityFillModel.

Slippage

The SamcoBrokerageModel uses the NullSlippageModel.

security.set_slippage_model(NullSlippageModel.instance);
security.set_slippage_model(NullSlippageModel.instance)

Fees

The SamcoBrokerageModel uses the SamcoFeeModel.

Buying Power

The SamcoBrokerageModel uses the SecurityMarginModel. If you have a margin account, the SamcoBrokerageModel allows up to 5x leverage.

Settlement

The SamcoBrokerageModel uses the ImmediateSettlementModel for margin accounts and the DelayedSettlementModel with the default settlement rules for cash accounts.

// For cash accounts:
security.SetSettlementModel(new DelayedSettlementModel(Equity.DefaultSettlementDays, Equity.DefaultSettlementTime));

// For margin accounts:
security.SetSettlementModel(new ImmediateSettlementModel());
# For cash accounts:
security.set_settlement_model(DelayedSettlementModel(Equity.DEFAULT_SETTLEMENT_DAYS, Equity.DEFAULT_SETTLEMENT_TIME))

# For margin accounts:
security.set_settlement_model(ImmediateSettlementModel())

Margin Interest Rate

The SamcoBrokerageModel uses the NullMarginInterestRateModel.
