Hi,

Unable to place order through API, other APIs work. However able to place an order through web platform.

Client ID :P479104

Please advice.

"Order placement failed: 'NoneType' object is not subscriptable"

Illustrative orderparams:
orderparams = {
"variety": "AMO",
"tradingsymbol": "CRUDEOIL21NOV630000PE",
"symboltoken": "233501",
"transactiontype": "BUY",
"exchange": "NFO",
"ordertype": "MARKET",
"producttype": "CARRYFORWARD",
"duration": "IOC",
"price": "0",
"squareoff": "0",
"stoploss": "0",
"quantity": 50 #quantity #lot size CRUDE 100, NIFTY 50
}

Tried with Normal, Day options as well, during the trading hours.

Hi @neeluru

We have noticed that you are experiencing issues with our SDK due to poor error handling. The error message you are seeing, "TypeError: 'NoneType' object is not subscriptable", is a result of the SDK not handling exceptions properly. This is causing the orderResponse variable to be None, which is leading to the error you are seeing.

The correct error message from the RestAPI is "Invalid Order Type" with error code "AB1020". This error is likely being caused because you are using the wrong value for the "variety" parameter. For STOPLOSS_MARKET orders, the acceptable input for the "variety" parameter is "STOPLOSS" and not "NORMAL".

Please note that our SDKs are open source, so you are welcome to make contributions to improve the error handling and other aspects of the code. Additionally, if you encounter any errors in the future, you can make a call to the RestAPI directly to get the correct error message and information on how to resolve the issue.

We apologize for any inconvenience this may have caused and thank you for your understanding.

error message from the RestAPI

Hi @admin
if my understanding is correct you mean to say that this error "'NoneType' object is not subscriptable" is due to wrong "variety" parameter. Please correct if I misunderstood it.

I am also facing the same issue regularly. I had already raised this, please see https://smartapi.angelbroking.com/topic/3398/error-while-placing-orders

And I checked the "variety" in order parameters, it is "NORMAL" for regular orders and "ROBO" for Bracket orders.

@laxm
below is piece of code..

try:
    orderparams = {
        "variety": "STOPLOSS",
        "tradingsymbol": str(tradingsymbol),
        "symboltoken": str(symboltoken),
        "transactiontype":"BUY",
        "exchange": "NFO",
        "ordertype": "STOPLOSS_LIMIT",
        "producttype": "CARRYFORWARD",
        "duration": "DAY",
        "price":pricelimit,
        "triggerprice":triggerprice,
        "squareoff": "0",
        "stoploss": "0",
        "quantity": "50"
        }
    orderId=obj.placeOrder(orderparams)
    return orderId
except Exception as e:
    print(orderparams)   # it's helpful to understand which values you've passed..
    print("Order placement failed: {}".format(e.message))

ROBO order is working fine for me.

try:
orderparams = {
"variety": "ROBO",
"tradingsymbol": str(tradingsymbol),
"symboltoken": str(symboltoken),
"transactiontype": str(transactiontype),
"exchange": str(symbolexchange),
"ordertype": "LIMIT",
"producttype": "BO",
"duration": "DAY",
"price":float(pricelimit),
#"triggerprice":100,
"squareoff": 12,
"stoploss": 12,
"quantity": str(quantity)
}
orderId=client_smartApi.placeOrder(orderparams)
return orderId
except Exception as e:
print("Order placement failed: {}".format(e.message))

I tried the above piece of code and it works perfectly with a valid "orderId" but the challenge is on the Angle Broking UI under "Open Orders" this is not reflected.
But if you get into "VIEW ORDER HISTORY" page it shows the following error:

Reason: 16408 : Trigger price entered has invalid characters

Below are the details and have attached the screenshot STOPLOSS order error on AngelOne UI01012023.png

HI @N210013

We have noticed that you are experiencing issues with our SDK due to poor error handling. The error message you are seeing, "TypeError: 'NoneType' object is not subscriptable", is a result of the SDK not handling exceptions properly. This is causing the orderResponse variable to be None, which is leading to the error you are seeing.

The correct error message from the RestAPI is "TPIN is not validated" with error code "AB4013". This error is likely being caused because you are trying to sell delivery holding without TPIN authorization. To read more about the same, please read this post on forums.

Hello @admin

I'm receiving this error very frequently, sometimes it goes good. For example, yesterday it failed to place the order and today it was able to place the order successfully (no changes made).
I'm following up on this error from many days through multiple threads. But I never got a solution. Can you please respond or make changes as to show the proper reason for the error.

Hope I'll get some resolution this time...Thanks in advance.
