Python API - Historical Data Fetch became arbitrary & DataFrame not coming after TOTP has been imposed
-
Historical Data Fetch became very arbitrary its not INTERNET connection problem. Yesterday night at 1 AM midnight all worked perfectly but today now during market hours now 10 AM around DataFrame not coming
The Code remained same as past before TOTP system using PYTHON
usr = SmartAPI(api_key,client_code,client_pass, totp)
if(usr.sessionData['status'] == True):
smartapiObj = usr.smartapiObj
else:
print("SmartAPI Object Session Data is not TRUE, exiting...")
exit()df = None
status = None
msg = None
stockObj = StockClass('NSE', symbol, token_mumber, smartapiObj)
df, status, msg = stockObj.getDF_Daily(no_of_candles, fromDate, todayDate)In the above code the class function stockObj.getDF_Daily() returns DataFrame only with status and message. All worked perfectly before TOTP. and in this function or class nothing about TOTP used. smartapiObj is generated using TOTP only
The Output shown by program
Checking NIFTY50 Stocks : Please wait..
