Updates

The WebullBrokerageModel 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 WebullBrokerageModel uses the EquityFillModel for Equity trades and the ImmediateFillModel for Equity Options and Index Options trades.

Slippage

The WebullBrokerageModel uses the NullSlippageModel.

Fees

The WebullBrokerageModel uses the WebullFeeModel.

Buying Power

The WebullBrokerageModel uses the SecurityMarginModel. If you have a margin account, the WebullBrokerageModel allows up to 2x leverage.

Settlement

The WebullBrokerageModel 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 WebullBrokerageModel uses the NullMarginInterestRateModel.

Default Markets

The default market of the WebullBrokerageModel is Market.USA.

Account Currency

The WebullBrokerageModel doesn't set a default currency. To change the algorithm's currency from USD to a different currency, see Set Account Currency.
