Forever Order on V2 API

APIs, Automation, Algos & Code
1

Hi DhanHQ API team and community,

I’ve been working with the v2 DhanHQ API, specifically with placing forever orders using the endpoint described at Forever Order - DhanHQ Ver 1.0 / API Document. I’ve run into an issue that I’m hoping someone can help me with or investigate.

When placing a forever order using the curl method, I’ve noticed that setting “productType”: “CNC” works fine and successfully places the order. However, when I try to use “productType”: “MTF”, it doesn’t work and returns an error.

“Order 7 response: 400 - {“errorType”:“Order_Error”,“errorCode”:“DH-906”,“errorMessage”:“Missing required fields, bad values for parameters etc.”}”

Here’s an example of the curl command I’m using:

curl --request POST \
    --url https://api.dhan.co/v2/forever/orders \
    --header 'Accept: application/json' \
    --header 'Content-Type: application/json' \
    --header 'access-token: <my-access-token>' \
    --data '{
        "dhanClientId": "1000000132",
        "orderFlag": "SINGLE",
        "transactionType": "BUY",
        "exchangeSegment": "NSE_EQ",
        "productType": "MTF",
        "orderType": "LIMIT",
        "validity": "DAY",
        "securityId": "1333",
        "quantity": 5,
        "disclosedQuantity": 1,
        "price": 1428,
        "triggerPrice": 1427
    }'

it is implemented, please check the v2 docs, but not going through the api, Dhan API

Hi @thiru ,
Can you share exact code which you are running, if possible?
DH-906 means Incorrect request for order and cannot be processed.
So data POST’ed to system seems to be incorrect.

This is the code

import http.client
import json

# Define the API endpoint and headers
conn = http.client.HTTPSConnection("api.dhan.co")

# Loop through each row in the DataFrame
for index, row in df_with_scrip_id.iterrows():
    
    order_data = {
        "dhanClientId": "11111111",
        "correlationId": "",
        "orderFlag": "SINGLE",
        "transactionType": "BUY",
        "exchangeSegment": "NSE_EQ",
        "productType": "MTF",
        "orderType": "LIMIT",
        "validity": "DAY",
        "securityId": str(row['SEM_SMST_SECURITY_ID']),
        "quantity": row['Buy Qty'],
        "disclosedQuantity": row['Buy Qty'],
        "price": row['price'],
        "triggerPrice": row['triggerPrice'],
        "price1": 0.0,
        "triggerPrice1": 0.0,
        "quantity1": 0
    }

    payload = json.dumps(order_data)

    headers = {
        'access-token': access_token,
        'Content-Type': 'application/json',
        'Accept': 'application/json'
    }

    # Send a POST request
    conn.request("POST", "/v2/forever/orders", payload, headers)

    res = conn.getresponse()
    data = res.read()

    # Print the response
    print(f"Order {index} response: {res.status} - {data.decode('utf-8')}")

i think these fields should not be included in payload.You already declared price once.

@Hardik please look into this

Hello @thiru

Can you keep disclosedQuantity as 0. Also, if you can send the JSON payload (not the python but actual request sent). This will help to debug faster.

hi @Hardik thanks for reply curl --request POST \ --url https://api.dhan.co/v2/forever/orders \ --header 'Accept: application/json' \ --header 'Content-Type: application/json' \ --header 'access-token: ' \ --data '{ "dhanClientId": "1101751259", "correlationId": "", "orderFlag": "SINGLE", "transactionType": "BUY", "exchangeSegment": "NSE_EQ", "productType": "MTF", "orderType": "LIMIT", "validity": "DAY", "securityId": "694", "quantity": 11.0, "disclosedQuantity": 0, "price": 1685.50, "triggerPrice": 1683.00, "price1": 0.0, "triggerPrice1": 0.0, "quantity1": 0.0 }' and this is the response { "errorType": "Order_Error", "errorCode": "DH-906", "errorMessage": "Missing required fields, bad values for parameters etc." }

@Hardik same works for CNC but not for MTF, kindly check.

13

Hello @thiru

Understood. Will try to replicate this and will get back to you.

14

Hello @thiru

Can you try now and confirm? We have made some changes at our end for the same.

15

Thank you for the effort @Hardik, but still same error, but the same works for CNC Forever order, "Order 0 response: 400 - {“errorType”:“Order_Error”,“errorCode”:“DH-906”,“errorMessage”:“Missing required fields, bad values for parameters etc.”}
"’

16

@Hardik any updates?

17

Hello @thiru

This has been fixed. Can you check once at your end?

18

Hi @Hardik , if i change “orderType”: “LIMIT” to “orderType”: “MARKET”, in the same payload the order doesnt go through, do we need to make change in Price or Triggerprice , if we are placing a market order via forever order, can you check if the APIs are well handled for this case in backend, kindly help
