Data Providers

IQFeed

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 with the QuantConnect Paper Trading brokerage.

To view the implementation of the IQFeed integration, see the Lean.DataSource.IQFeed repository.

Deploy Local Algorithms

Follow these steps to start local live trading with the IQ Feed data provider:

  1. Log in to the CLI if you haven't done so already.
  2. Open a terminal in the organization workspace that contains the project.
  3. Run lean live deploy "<projectName>" to start a live deployment wizard for the project in . / <projectName> 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) Terminal Link
11) Trading Technologies
12) Kraken
13) Charles Schwab
14) Bybit
15) TradeStation
16) Alpaca
Enter an option: 1
  4. 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) Terminal Link
10) Trading Technologies
11) Kraken
12) Charles Schwab
13) IQFeed
14) Polygon
15) IEX
16) CoinApi
17) ThetaData
18) Custom data only
19) Bybit
20) TradeStation
21) Alpaca
To enter multiple options, separate them with comma:
  5. 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]:
  6. Enter your IQFeed username and password. 
    $ lean live "My Project"
Username: 123456
Password: **********
  7. If you have an IQFeed developer account, enter the product Id and version of your account. 
    $ lean live "My Project"
Product id: <yourID>
Product version: 1.0
  8. 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
  9. View the result in the <projectName> / live / <timestamp> directory. Results are stored in real-time in JSON format. You can save results to a different directory by providing the --output <path> option in step 2.

If you already have a live environment configured in your Lean configuration file, you can skip the interactive wizard by providing the --environment <value> option in step 2. 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:

Mutiple Data Providers

When you deploy a live algorithm, you can add multiple data provider. If you use multiple data providers, the order you select them in defines their order of precedence in Lean.
