Append `?lang=csharp` to this URL for the C# version of this page. ## Introduction Instead of using the data from your brokerage, you can also use IQFeed if you're on Windows. Using IQFeed requires you to have an IQFeed developer account and you need to have the IQFeed client installed locally. This tutorial demonstrates how to set up the [IQFeed data provider](https://www.quantconnect.com/docs/v2/lean-cli/datasets/iqfeed.md) with the QuantConnect Paper Trading brokerage. To view the implementation of the IQFeed integration, see the [Lean.DataSource.IQFeed repository](https://github.com/QuantConnect/Lean.DataSource.IQFeed). To use the CLI, you must be a member in an [organization](https://www.quantconnect.com/docs/v2/cloud-platform/organizations/tier-features.md) on a paid tier. ## Deploy Local Algorithms Follow these steps to start local live trading with the IQ Feed data provider: 1. [Log in](https://www.quantconnect.com/docs/v2/lean-cli/initialization/authentication.md#02-Log-In) to the CLI if you haven't done so already. 2. Open a terminal in the [organization workspace](https://www.quantconnect.com/docs/v2/lean-cli/initialization/organization-workspaces.md) that contains the project. 3. If your algorithm trades US Equities, Options, or Futures, [purchase and download](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect.md) the QuantConnect datasets that LEAN uses for the asset class. Crypto, Forex, and CFD algorithms can skip this step. The following table shows the datasets for each asset class: | Asset Class | Datasets | | --- | --- | | US Equity | [US Equity Security Master](https://www.quantconnect.com/datasets/quantconnect-us-equity-security-master/cli), to get adjusted prices. Without it, your algorithm uses raw prices. | | US Equity Options | [US Equity Security Master](https://www.quantconnect.com/datasets/quantconnect-us-equity-security-master/cli) and [US Equity Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-equity-option-universe) | | US Index Options | [US Index Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-index-option-universe) | | US Futures | [US Futures Security Master](https://www.quantconnect.com/datasets/quantconnect-us-futures-security-master/cli) and [US Future Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-universe) | | US Future Options | [US Futures Security Master](https://www.quantconnect.com/datasets/quantconnect-us-futures-security-master/cli), [US Future Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-universe), and [US Future Option Universe](https://www.quantconnect.com/datasets/quantconnect-us-future-option-universe). To get access, [contact us](https://www.quantconnect.com/contact). | If your algorithm uses [universe selection](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/key-concepts.md), also download the universe dataset, such as the [US Equity Coarse Universe](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect/us-equity-coarse-fundamental.md) or [US ETF Constituents](https://www.quantconnect.com/docs/v2/lean-cli/datasets/quantconnect/us-etf-constituents.md). 4. Run `lean live deploy ""` to start a live deployment wizard for the project in `. / ` and then enter a brokerage number. ``` $ lean live deploy "My Project" Select a brokerage: 1) Paper Trading 2) Interactive Brokers 3) Tradier 4) OANDA 5) Bitfinex 6) Coinbase Advanced Trade 7) Binance 8) Zerodha 9) Samco 10) Quant Bridge 11) Trading Technologies 12) Kraken 13) Charles Schwab 14) Bybit 15) TradeStation 16) Alpaca 17) Tastytrade 18) Eze 19) dYdX 20) Webull 21) Public 22) Clear Street ``` 5. Enter the number of the live data provider(s) to use and then follow the steps required for the data connection. ``` $ lean live deploy "My Project" Select a live data provider: 1) Interactive Brokers 2) Tradier 3) Oanda 4) Bitfinex 5) Coinbase Advanced Trade 6) Binance 7) Zerodha 8) Samco 9) Quant Bridge 10) Trading Technologies 11) Kraken 12) Charles Schwab 13) IQFeed 14) Polygon 15) CoinApi 16) ThetaData 17) Custom data only 18) Bybit 19) TradeStation 20) Alpaca 21) Tastytrade 22) Eze 23) dYdX 24) DataBento To enter multiple options, separate them with comma: ``` 6. Enter the path to the IQConnect binary. The default path is `C: / Program Files (x86) / DTN / IQFeed / iqconnect.exe` if you used the default settings when installing the IQFeed client. ``` $ lean live "My Project" IQConnect binary location [C:/Program Files (x86)/DTN/IQFeed/iqconnect.exe]: ``` 7. Enter your IQFeed username and password. ``` $ lean live "My Project" Username: 123456 Password: ********** ``` 8. If you have an IQFeed developer account, enter the product Id and version of your account. ``` $ lean live "My Project" Product id: Product version: 1.0 ``` 9. If you don't have an IQFeed developer account, open `iqlink.exe`, log in to IQLink with your username and password, and then enter random numbers for the product id and version. ``` $ lean live "My Project" Product id: 123 Product version: 1.0 ``` 10. View the result in the ` / live / ` directory. Results are stored in real-time in JSON format. You can save results to a different directory by providing the `--output ` option in step 4. If you already have a live environment configured in your [Lean configuration file](https://www.quantconnect.com/docs/v2/lean-cli/initialization/configuration.md#03-Lean-Configuration), you can skip the interactive wizard by providing the `--environment ` option in step 4. The value of this option must be the name of an environment which has `live-mode` set to `true`. ## Deploy Cloud Algorithms The CLI doesn't currently support deploying cloud algorithms with the IQFeed data provider. ## Supported Assets Our IQFeed integration supports securities from the following asset classes: - [US Equity](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/us-equity.md) - [US Equity Options](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/equity-options.md) - [Forex](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/forex.md) (listed on FXCM) - [US Futures](https://www.quantconnect.com/docs/v2/writing-algorithms/securities/asset-classes/futures.md) The IQFeed data provider serves raw data. To get adjusted Equity data in local deployments, [download the US Equity Security Master](https://www.quantconnect.com/datasets/quantconnect-us-equity-security-master/cli). To get [continuous Futures](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/futures.md#12-Continous-Contracts) data in local deployments, [download the US Futures Security Master](https://www.quantconnect.com/datasets/quantconnect-us-futures-security-master/cli). ## Mutiple Data Providers When you [deploy a live algorithm](https://www.quantconnect.com/docs/v2/lean-cli/live-trading/data-providers/iqfeed.md#02-Deploy-Local-Algorithms), you can add multiple data providers. If you use multiple data providers, the order you select them in defines their order of precedence in Lean.
