Hi @Nitin_06,

Apologies for the delayed response.

Please try using the below code in market hours and let us know if you face the same issue.

from SmartApi.smartWebSocketV2 import SmartWebSocketV2
from logzero import logger

AUTH_TOKEN = "auth_token"
API_KEY = "api_key_here"
CLIENT_CODE = "client_code"
FEED_TOKEN = "feed_token"
correlation_id = "abc123"// any string value
action = 1
mode = 3
token_list = [
    {
        "exchangeType": 1,
        "tokens": ["26009"]
    }
]
#retry_strategy=0 for simple retry mechanism
sws = SmartWebSocketV2(AUTH_TOKEN, API_KEY, CLIENT_CODE, FEED_TOKEN)

#retry_strategy=1 for exponential retry mechanism
# sws = SmartWebSocketV2(AUTH_TOKEN, API_KEY, CLIENT_CODE, FEED_TOKEN,max_retry_attempt=3, retry_strategy=1, retry_delay=10,retry_multiplier=2, retry_duration=30)

def on_data(wsapp, message):
    logger.info("Ticks: {}".format(message))
    # close_connection()

def on_control_message(wsapp, message):
    logger.info(f"Control Message: {message}")

def on_open(wsapp):
    logger.info("on open")
    some_error_condition = False
    if some_error_condition:
        error_message = "Simulated error"
        if hasattr(wsapp, 'on_error'):
            wsapp.on_error("Custom Error Type", error_message)
    else:
        sws.subscribe(correlation_id, mode, token_list)
        # sws.unsubscribe(correlation_id, mode, token_list1)

def on_error(wsapp, error):
    logger.error(error)

def on_close(wsapp):
    logger.info("Close")

def close_connection():
    sws.close_connection()


# Assign the callbacks.
sws.on_open = on_open
sws.on_data = on_data
sws.on_error = on_error
sws.on_close = on_close
sws.on_control_message = on_control_message

sws.connect()
