# Run the loop for the trading days in the last one year
for i in last_one_year.index:
# Check the conditions to generate signals only if the counter is greater or equal to 5
if days_since_last_signal >= 5:
# ****Step-1: Select the 4 years of daily options data before the selected date****
four_years_data = options_data[:i][-252*4:]
four_years_data.index = pd.to_datetime(four_years_data.index)
In this strategy, I don't really understand the purpose for counter >=5. My understanding trading period period only 5 working days, but why it is 5 days, not 10 days, or stopping at the strike price in the money.
