Here is the working sample code to Place Orders:

from smartapi import SmartConnect 

obj = SmartConnect(api_key="your_api_key")
data = obj.generateSession('client_id', 'your_password')
refreshToken= data['data']['refreshToken']

orderparams = {
    "variety": "NORMAL",
    "tradingsymbol": "symbol",
    "symboltoken": "token",
    "transactiontype": "BUY",
    "exchange": "NFO",
    "ordertype": "MARKET",
    "producttype": "INTRADAY",
    "duration": "DAY",
    "quantity": "quantiy"
 }
orderId = obj.placeOrder(orderparams)
print(orderId)

Above code just punch order and returns orderId of particular order.

I too used web scraping to get upcoming expiry. Little code of Scrapy or BeautifulSoup does the job very well.

@rajanprabu How many ticks you receive per second for a single symbol? I'm getting more than 3 ticks/sec for a symbol.

@admin Why I'm getting more than 1 tick/sec. Anything changed in WebSocket response ? Also WebSocket getting closed randomly.

@admin

(2021-05-18 14:44:42,193)  -  (Connection error: 1006 - connection was closed uncleanly (peer dropped the TCP connection without previous WebSocket closing handshake))
(2021-05-18 14:44:42,194)  -  (Connection closed: 1006 - connection was closed uncleanly (peer dropped the TCP connection without previous WebSocket closing handshake))
