What does it mean when your available balance is more negative than your ledger balance?

I'm talking about a checking account. I checked my balance at an ATM machine and was negative 31 dollars, but that was just ledger. My available balance was negative 130 or something like that..|||Your available balance means what is available to you after transactions that are pending have gone through. If you are already negative in your available balance and have transactions still pending your available balance will continue to grow a negative balance, higher and higher, then you need to add in with every item that is in pending goes through you will get hit with a overdraft fee for every item. So if you have 5 items pending and your account is already negative you will get hit with 5 overdraft fees, depending on you banks fees it can be around 30.00 each. 30.00x5=150, add that to your already negative balance and your in deep! good luck and remember if you are just going by what the ATM is telling you, remember that the ATM can only give you a limited amount of info. online banking and using and ledger and writing everything down in it to keep up with what you are spending is the only way to keep track of your spending. Dont go by what the ATM tells you PLEASE! It is punishable in a court of law and if you are writing checks as well as using your card it can get you jail time. Talk to your bank if you are at all worried, they will more than likely work with you.|||It probably means you have more transactions pending to go through and that will be your balance once those transactions clear. It probably doesn't factor in overdraft fees, so expect to be even more negative.|||you're overdrawn and becoming more so every day. make a deposit to your account NOW or it will get worse.
