showMyTrades returns nothing about btcde

[js931]

I found a way to make it work, you have to pass the "state" argument: state=1
It is described as "optional" in the API docs, but if you actually want to receive some data, you have to pass it to the function!

Additional note: If i try to pass an argument to the function, an error occurs.
trades = conn.showMyTrades(type='buy')
