Hi @Tradehull_Imran sir, today I observed one strange thing, I would be happy if you help me on this:This was one of the buying/selling condition:
chart = tsl.get_historical_data(stock_name, “NSE”, “5”)
lcc_chart = chart.iloc[-2]
bc3 = chart.iloc[-2]['CDLENGULFING'] == 100
In this case I am getting value of true or false in bc3.
But problem in this case is:
chart = tsl.get_historical_data(stock_name, “NSE”, “5”)
lcc_chart = chart.iloc[-2]
bc3 = lcc_chart['CDLENGULFING'] == 100
Output:

For your information line 47 refers to sc3 = lcc_chart[‘CDLENGULFING’] == -100.
Kindly help me on this.
Thank you in advance.
Hi @nitinsubudhi ,
The error occurs because CDLENGULFING is not a column in the DataFrame. Accessing a non-existent column from a row Series will always raise a KeyError.
when i try to run my python file i get this error Traceback (most recent call last):
