Group by and add or subtract depending on the indicator - powershell

Question

I have a file which has transaction_date, transaction_amount and debit_credit_indicator. I want to write a program which shows for each date total count and total amount.
Total amount is calculated as follows -
if debit_credit_indicator is 'C' add else if 'D' subtract.
I got till grouping by indicators but don't know how to proceed after wards.
My ouput looks like this
TRANSACTION_DATE DEBIT_CREDIT_INDICA TotalAmount Count
TOR
---------------- ------------------- ----------- -----
2019-02-26 C 1478
2019-02-25 D 100
2019-02-26 D 200
param([string]$inputFileName=30)
(Get-Content $inputFileName) -replace '\|', ',' | Set-Content c:\learnpowershell\test.csv
$transactionData = Import-csv c:\learnpowershell\test.csv | Group-Object -Property TRANSACTION_DATE, DEBIT_CREDIT_INDICATOR
[Array] $newsbData += foreach($gitem in $transactionData)
{
$gitem.group | Select -Unique TRANSACTION_DATE, DEBIT_CREDIT_INDICATOR, `
#{Name = ‘TotalAmount’;Expression = {(($gitem.group) | measure -Property TRANSACTION_AMOUNT -sum).sum}},
#{Name = ‘Count’;Expression = {(($gitem.group) | Measure-Object -count).count}}
};
write-output $newsbData

I suppose you want replace '|' by ',' because you dont know -delimiter option otherwise keep you code for replace. now i propose my code for your problem:
#import en group by date
import-csv "c:\learnpowershell\test.csv" -Delimiter '|' | group TRANSACTION_DATE | %{
$TotalCredit=0
$TotalDebit=0
$CountRowCredit=0
$CountRowDebit=0
$HasProblem=$false
#calculation by date for every group
$_.Group | %{
if ($_.DEBIT_CREDIT_INDICATOR -EQ 'C')
{
$TotalCredit+=$_.transaction_amount
$CountRowCredit++
}
elseif ($_.DEBIT_CREDIT_INDICATOR -EQ 'D')
{
$TotalDebit+=$_.transaction_amount
$CountRowDebit++
}
else
{
$HasProblem=$true
}
}
#output result
[pscustomobject]#{
TRANSACTION_DATE=$_.Name
CountRow=$_.Count
Credit_Total=$TotalCredit
Credit_CountRow=$CountRowCredit
Debit_Total=-$TotalDebit
Debit_CountRow=$CountRowDebit
Total_DebitCredit=$TotalCredit - $TotalDebit
HasProblem=$HasProblem
}
}
You can add ' | Format-Table ' if you want print result formated in table
