## Introduction

This page explains the `OandaBrokerageModel`, including the asset classes it supports, its default [security-level models](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/key-concepts.md#02-Security-Level-Models), and its default markets.

```python
self.set_brokerage_model(BrokerageName.OANDA_BROKERAGE, AccountType.MARGIN)
```

For more information about this model, see the [class reference](https://www.lean.io/docs/v2/lean-engine/class-reference/py/QuantConnect/Brokerages/OandaBrokerageModel/) and [implementation](https://github.com/QuantConnect/Lean/blob/master/Common/Brokerages/OandaBrokerageModel.cs).

## Asset Classes

The `OANDABrokerageModel` supports trading [Forex](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/forex.md) and [CFDs](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/cfd.md).

## Orders

The `OandaBrokerageModel` supports several order types, the `TimeInForce` order property, and order updates.

### Order Types

The following table describes the available order types for each asset class that the `OANDABrokerageModel` supports:

| Order Type | Forex | CFD |
| --- | --- | --- |
| [Market](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/market-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) |
| [Limit](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/limit-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) |
| [Stop market](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/stop-market-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) |
| [Stop limit](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-types/stop-limit-orders.md) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) | ![green check](https://cdn.quantconnect.com/i/tu/check.png) |

### Time In Force

The `OANDABrokerageModel` the `GOOD_TIL_CANCELED` [TimeInForce](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-properties.md#03-Time-In-Force).

```python
self.default_order_properties.time_in_force = TimeInForce.GOOD_TIL_CANCELED
self.limit_order(self._symbol, quantity, limit_price)
```

### Updates

The `OANDABrokerageModel` supports [order updates](https://www.quantconnect.com/docs/v2/writing-algorithms/trading-and-orders/order-management/order-tickets.md#04-Update-Orders).

## Fills

The `OandaBrokerageModel` uses the [ImmediateFillModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/trade-fills/supported-models/immediate-model.md).

## Slippage

The `OandaBrokerageModel` uses the [NullSlippageModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/slippage/supported-models.md#02-Null-Model).

## Fees

The `OandaBrokerageModel` uses the [ConstantFeeModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/transaction-fees/supported-models.md#02-Constant-Model) with zero fees. OANDA offers "Spread" and "Core + Commission" pricing models. Our data is the spread dataset, so we model the spread pricing. To estimate OANDA Core+Commission data, use a [custom fee model](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/transaction-fees/key-concepts.md#04-Model-Structure) and a [custom fill model](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/trade-fills/key-concepts.md#04-Model-Structure).

```python
security.set_fee_model(ConstantFeeModel(0))
```

## Buying Power

The `OandaBrokerageModel` uses the `SecurityMarginModel` and allows up to 50x leverage.

## Settlement

The `OandaBrokerageModel` uses the [ImmediateSettlementModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/settlement/supported-models.md#02-Immediate-Model) for Forex trades and the [AccountCurrencyImmediateSettlementModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/settlement/supported-models.md#04-Account-Currency-Immediate-Model) for CFD trades.

## Margin Interest Rate

The `OandaBrokerageModel` uses the [NullMarginInterestRateModel](https://www.quantconnect.com/docs/v2/writing-algorithms/reality-modeling/margin-interest-rate/supported-models.md#02-Null-Model).

## Default Markets

The default market of the `OandaBrokerageModel` is `Market.OANDA`.

## Account Currency

The `OandaBrokerageModel` doesn't set a default currency. To change the algorithm's currency from USD to a different currency, see [Set Account Currency](https://www.quantconnect.com/docs/v2/writing-algorithms/initialization.md#03-Set-Account-Currency).
