KMyMoney: Version 5.1.80-a418cd886 KMymoney shows incorrect balance values for credit cards in ledger and all net worth reports. Steps to reproduce: 1. Create new book with checking account, balance = 0 (name = Direct) 2. Add new credit card account (name=Visa) 3. Add new deposit transaction in checking account, value=20000 3. Just transfer 10000 from checking account to credit card account. Expected result: 1. In Assets and Liabilities Summary in the dashboard net worth should be 20000, checking account balance should be 10000, credit card account should be 10000. Result OK! 2. In credit card ledger, the balance in the row with transfer should be 10000, but the result is -10000. Result FAILED! 3. In credit card ledger total balance should be 10000. Result OK! 4. Net worth for credit card after the transfer transaction in net worth reports should be 10000, but there is -10000. Result FAILED!

This is just how KMyMoney works. A Credit Card Account is a Liability, and Liability Accounts display positive numbers in the ledger - showing how much you owe - a positive liability. In your case, you don't owe anything, you have 10000 available, essentially a negative liability. The numbers are reversed on the home view - I suppose you could just call it convention, or for convenience of seeing both assets and liabilities together.
I think this is a good reason to show both debits and credits(accounting terms) rather than use positive and negative values. Then the values could be absolute and never negative. Standard double accounting, but it will be a little more difficult for those not familiar with double accounting. From the user post, I do not think the result failed, rather it did not show what the user expected. Negatives vs positive values rather than absolute values. Maybe give an option to switch between both views?
The new ledger (currently only seen in versions compiled from master branch, no schedule for release yet) moves in that direction with separate fields in the ledger (Payment and Deposit in asset accounts, I can't check the names in Liability accounts). The only down side is that it takes two columns, so it's not great on smaller screens, or if ever ported to mobile. The idea of an option to control that might be worth filing as a wishlist.
