Pretty big newbie looking for some guidance here...
I have a script already, but I am stuck at some basic calculations which are easy to do in other platforms like TradingView (but have their own limitations) which have me guessing at what to do next. I have the data frame of the security (date and close columns). Now I want to count the number of days the security closed below the previous day's close before it closed above it.
For instance, Day 1: 192 Day 2: 191: day 3: 192 would be 2.
How would I do this?

When creating a function like this it is important to think about the parameters and the return value. In this case, the return value is just an integer for the number of days. But what would the parameters be? In the fixed case above a simple script would be:
# for this example a list of prices was chosen to iterate through def sample(list): #the number of days counter = 0 #index in the list i = 0 while(True): previous_close = list[i] current_close = list[i+1] #checks if previous_close is less if(previous_close < current_close): #goes to next day and increases the day count counter++ i++ else: #returns the number of days return counterAn implementation using the same code provided would be creating a list, calling the function on each day in the period, and adding the number to the list. The resulting list would have the number of days "the security closed below the previous day's close before it closed above it" for each day in the period.

Thanks so much for the response! I follow the logic of the formula you provided but I could not get it to work with my dataframe. Could you help me use it on my dataframe?
