@trictors:
Is looks to the software that it is trying to sell (or buy) coins that are not there. The messages you are seeing are telling this, i recommend you check your trade-amount and coin-position.
The only thing, that could be causing this problem, from me not having enough coins.
Is say if your account has 0 ltc, Your program buys 50. Then when it sells it attempts to use other ltc in your account that it didnt even buy.
Either way its an error, and not a user error correct?
And in plainer english, If you have 1000USD, and 0 LTC. you should be able to start your bot on LTC/USD.

It bought the coins itself, it should know exactly how much it has to sell because it bought it. The coins are there. the position changed.
