Please remember to cc the list on your replies. You can use "reply all" or, if your mail client supports it, "reply list".

The developer list is for discussing development of Gnucash itself, not scripting or even custom reports. Those are user activities.

The next problem is that you don't "update your balance" in Gnucash. Gnucash calculates the balance of an account from the transactions which you enter or import. Alternatively, if you are interested in updating the current value of some "electronic-currency" scrip in a real currency (US Dollars or Euros, perhaps), you would import price information, treating the scrip like a stock. No coding is required to import transactions provided they're formatted in a way that Gnucash already understands. Importing properly formatted price data is also pretty straightforward, but it's not exposed via the command line or GUI so you would need a small script to call the requisite functions. Take a look at src/scm/price-quotes.scm to see what you'd need to do.
