This CSV file contains the results of my investments.

The column containing the profit/loss is the column named back

And I want to test it like this:

Let’s assume that I want to see the total profit only for the investments I would make if according to some filters this investment pattern was profitable in previous records.

Example:

The 51st investment is 'market_name' → Over/Under 2.5 Goals, 'runner_name' → Under 2.5 Goals and 'odds' → 1.24

So I want to sum the profit/loss of 50th previous investments if they have these same filters, if the sum of these filters is greater than zero, then I make investment 51.

And so on in each of the lines, 100th investment, I see if the previous 99 investments filtering the cited options will be profitable, if so, I add the back column of 100th to the list for final sum.

So I created this code:

import pandas as pd

df = pd.read_csv(test.csv')
df = df[df['result'].notnull()]

matches = []

for number in range(len(df)):
    try:
        dfilter = df[:number]
        filter = dfilter[(dfilter['market_name'] == df['market_name'][number+1]) & (dfilter['runner_name'] == df['runner_name'][number+1]) & (dfilter['odds'] == df['odds'][number+1])]
        back_sum = filter['back'].sum()
        if back_sum > 0:
            matches.append(df['back'][number+1])
    except:
        pass

print(sum(matches))

But the final sum is delivering a result that does not match my real results where I invest.

I can’t find where the flaw is in the code because it looks correct to me visually.

Answers:

Slice df[:number] means to take elements up to number. And when referring to the current line, you must use number, not number+1. This can be checked, for example, print df[:3] and get all the lines up to the third one.

But if you use loc, then operations through the slice will not be up to, but inclusive (you should not forget about this). That is, with df.loc[:3, :] rows will be selected, including the third one.

That is, you need this:

for number in range(len(df)):
    try:
        dfilter = df[:number]
        filter = dfilter[(dfilter['market_name'] == df['market_name'][number]) &
                         (dfilter['runner_name'] == df['runner_name'][number]) & (dfilter['odds'] == df['odds'][number])]

        back_sum = filter['back'].sum()
        if back_sum > 0:
            matches.append(df['back'][number])
    except:
        pass

If the dataframe is large, the loop will be slow. I can recommend List comprehension, which is many times faster than a loop. Below I made a column ‘invest’, where, depending on back_sum, the values will be True or False.

df = pd.read_csv('test.csv')

#df = df[df['result'].notnull()].reset_index(drop=True)
"""
is whether all indexes of the original dataframe are needed,
if not, then you can add this line and use the filtered dataframe(if you need a filtered dataframe,
uncomment this line df = df[df['result'].notnull()].reset_index(drop=True))
"""

def my_func(i):
    dfilter = df[:i]
    filter = dfilter[(dfilter['market_name'] == df['market_name'][i]) &
                     (dfilter['runner_name'] == df['runner_name'][i]) & (dfilter['odds'] == df['odds'][i])]
    back_sum = filter['back'].sum()
    aaa = True
    if back_sum <= 0:
        aaa = False

    return aaa

df['invest'] = [my_func(i) for i in range(len(df))]
