Hello, What's an Ans my last question

Okay, thanks for your response.
But the F&O stocks are not getting placed. For example, I tried using the token ‘107755’ for ‘HDFCBANK25NOV25930CE’, and I’m creating the payload exactly the same way as I shared with you earlier.
We’ve also purchased multiple F&O stocks, but the orders are still not being placed.

Ok Thank you for reply
Do the stock symbols in your OpenScript master JSON file change every day?
If yes, is there any Angel One API available that provides updated stock prices along with token and symbol names properly?

Hi Angel One Team,

I’m facing an issue while placing orders through the SmartAPI https://apiconnect.angelone.in/rest/secure/angelbroking/order/v1/placeOrder endpoint.
The same API works fine for most symbols, but for some NFO option tokens it returns “400 Bad Request” with no proper error message in the response.

Here’s an example payload that fails:

{
"variety": "NORMAL",
"tradingsymbol": "FINNIFTY28OCT2527600PE",
"symboltoken": "57121",
"transactiontype": "BUY",
"exchange": "NFO",
"ordertype": "MARKET",
"producttype": "NRML",
"duration": "DAY",
"price": "0",
"squareoff": "0",
"stoploss": "0",
"quantity": "65"
}

I’ve already checked:

Token and symbol are from the latest OpenAPIScripMaster.json
All headers (API key, Bearer token, IP, MAC, etc.) are correctly added
Other tokens work fine using the same setup
Could you please confirm why some tokens return 400 with no message?
Is it due to token expiry, contract restriction, or product type issue?
Also, can you help me get more detailed error logs for debugging?

@admin Thanks for the reply...the link and the suggestion which you provided to me provided already we have done. Still we are getting mismatch error. Please find the below message which we are receiving
"data": null,
"isSuccess": true,
"errorMessage": "The order cannot be processed as the token is categorised under cautionary listings by the exchange."
},

Where i can find " Surveillance Indicator new" api to fetch daily data ...So that we can put it in our application

Hello Angel One Support Team,

I am facing repeated issues while placing orders through the Angel One API for certain stocks, such as IDEA-EQ (symbol token: 14366) on NSE.

The API sometimes returns the following errors even when all details are correctly filled:
1. "The order cannot be processed as the token is categorised under cautionary listings by the exchange."
2. "Entered trading symbol and symbol token is mismatch" (AB1019)

I would like to understand:
1. Why certain stocks are categorized under cautionary listing and if they will be tradable in the future.
2. Why the symbol-token mismatch occurs even when the correct symbol and token are used.
3. If there is any way to programmatically check both the cautionary status and correct symbol-token mapping before placing an order via API to avoid these failures.

Request you to provide guidance or resolution so that these repeated order issues can be avoided.

Thank you,
