There are two methods to install uTrade Connect:

1. Using pip:

   uTrade Connect is available on PyPI and can be installed using pip. Ensure you have Python 3.8 or above and internet access. Run the following command in your terminal:

   pip install utradeconnect

2. Using the provided shell script:

   Alternatively, you can use the runPackage.sh shell script provided in the project's root directory. This script creates a Python wheel for the project and installs it. To use this method, navigate to the project's root directory in your terminal and run the following command:

   sh runPackage.sh

After installation, check the config.ini file in the project's root directory and ensure you add the root url, keep source as WEBAPI, and disable_ssl as true.

There are two methods to configure base parameters for uTrade Connect:

1. Using config.ini:

configure an .ini file named as config.ini in your application's working directory, the sample content is as below:

    [user]
    source=WEBAPI

    [SSL]
    disable_ssl=True

    [root_url]
    root="Provided Url"
    broadcastMode=Full

2. Passing root url, disable_ssl while creating uTrade Connect Object

connect_object = UtradeConnect(
      apiKey=<your_api_key>,
      secretKey=<your_secret_key>,
      source=<source>,
      root=<provided_url>,
      debug=<debug_mode_boolean>,
      disable_ssl=<boolean>
  )            

• API Credentials and Config

    API_KEY = "YOUR_API_KEY_HERE"
    API_SECRET = "YOUR_API_SECRET_HERE"
    source = "WEBAPI"
    BASE_URL = "Provided Url"
  

  To securely manage your API credentials, it is recommended to use a .env file in your project

• uTradeConnect

  • Instantiate a UtradeConnect object by specifying your API appKey, secretKey, source, root[optional] as parameters when employing market APIs.

  • Conversely, if interactive APIs are preferred, furnish the requisite credentials for interactive functionality.

    utradeConnect = UtradeConnect(api_key=API_KEY, secretKey=API_SECRET, source=source, root=BASE_URL)

• Login ( API authentication )

  • To initiate API authentication, invoke the login service, which will provide a token for continued access to various services throughout the session.

    • Marketdata Login

          response = utradeConnect.marketdata_login()

    • Interactive Login

      The acquisition of an access token is mandatory for client interactive login.

      • For Client Interactive login

         response = utradeConnect.interactive_login(accessToken)

• Subscribe Symbol

  To commence a subscription to a specific symbol, employ the marketdata API. This API facilitates the retrieval of a Subscribe Response object, which encapsulates relevant tick data, including metrics such as Last Traded Price (LTP), Open, High, and other pertinent information, depending on the subscribed event type
  • CandleData event: 1505
  • Index event: 1512
  • MarketDepth event: 1502
  • Market event: 1507
  • OpenInterest event: 1510
  • TouchLine event: 1501

        instruments = [
              {"exchangeSegment": 1, "exchangeInstrumentID": 22},
              {"exchangeSegment": 1, "exchangeInstrumentID": 2885},
          ]
    
        response = utradeConnect.send_subscription(
              instruments=instruments, eventCode=1501
          )

• Quotes

  • The Quote service furnishes details pertaining to Asks, Bids and other pertinent information

         instruments = [
               {"exchangeSegment": 1, "exchangeInstrumentID": 22},
               {"exchangeSegment": 1, "exchangeInstrumentID": 2885},
           ]
    
         response = utradeConnect.get_quote(
               instruments=instruments, eventCode=1501, publishFormat="JSON"
           )

• Place Order Request

  • To execute an order, leverage the Interactive API. The resulting response will include an AppOrderId.

          response = utradeConnect.place_order(
            exchangeSegment="NSECM",
            exchangeInstrumentID=2885,
            productType="MIS",
            orderType="LIMIT",
            orderSide="BUY",
            timeInForce="DAY",
            disclosedQuantity=0,
            orderQuantity=10,
            limitPrice=300,
            stopPrice=0,
            orderUniqueIdentifier="123abc",
            clientID="C1",
        )

• Cancel Order Request

  • To cancel an order, leverage the Interactive API. The resulting response will include an AppOrderId.

          response = utradeConnect.place_order(
            appOrderID = OrderID
            clientID="C1",
        )

Refer to the Python client postman documentation for the complete list of supported methods.

• Market WebSocket

  Transmission of events, including TouchLine, MarketData, CandleData, OpenInterest, and Index, occurs through the socket. To capture these events, implementation of the UtradeAPIMarketdataEvents interface is required. The relevant events will be received through the methods that are specifically overridden within this interface.

  • Connecting to Marketdata socket

        # Authenticate to obtain an authorization token if you are not currently logged in.
        response = utradeConnect.marketdata_login()
        # Store the token and userid
        set_marketDataToken = response['result']['token']
