[klllmmm]

Hi @tirtha9,

Good day!

Hope the below answer helps

df2['ISBearish'] = df2['Date'].apply(lambda x: (Scanner(df2, x).isbearish2()))
print(df2)

Output:
	Date	Open	High	Low	Close	ISBearish
0	2020-01-31	788.00	791.50	764.00	767.1	True
1	2020-02-01	771.85	798.00	728.40	742.8	None
2	2020-02-03	754.00	794.95	752.45	785.7	None
3	2020-02-04	784.70	794.50	773.60	776.9	None
