Hi @Hardik ,

I am facing following error again i have attached the exact payload which i am using. The same payload worked yesterday but its not working today. It is really very painful to see such error messages after taking data subscription and top of that question raise is Dhan a capable platform for algo traders?

{
    “securityId”: “17971”,
    “exchangeSegment”: “NSE_EQ”,
    “instrument”: “EQUITY”,
    “expiryCode”: 0,
    “oi”: False,
    “fromDate”: “2025-08-24”,
    “toDate”: “2025-09-24”

}
headers = {
    “access-token”: “***”,
    “Content-Type”: “application/json”,
    “Accept”: “application/json”

}

{'errorType': 'Input_Exception', 'errorCode': 'DH-905', 'errorMessage': 'Missing required fields, bad values for parameters etc.'}

@Shrutika_Poojari @haricharan this error occurs when the api doesn’t have the historic data, I too have faced the same problem if you want to test just try fetching after 12:00 Am of yesterday’s data you will get the same error. But you if you fetch in morning before the market opens you will get the result.
