Because ,my friend your license is tied to your api key that will be used in the bot.And if you had some previous experience with bot trading and how api/secret works you wouldn ask that question.

P.S. Guys dont ask for vouch copy if you dont have any previous experience with trading bots or at least have a minimum understanding of how those things works.Thanks!

Sorry, there is no trials.Only vouch copies (2 left).Im giving 1 each 24hours.Feel free to apply for a copy.

Im not sure what you consider as "bug".Let me explain what you see in the output log and how it is getting to that point.

When the bot found an arbitrage opportunity it compares your balance per trade to the available volume at the specified price.The trades are executed only if the volume is few times higher than your balance per trade(currently set to 3 * pair1AmountToBuy, 9 * pair2AmountToBuy and 3 * pair3AmountToSell), so the bot is not initializing trades on lower volumes than needed.Sometimes due to server/network latency and/or other factors(someone else bought it before you and etc) the amount (in this example BTCD) you want to buy may become unfilled.So in that case we are left with XMR balance.Those balance is added to the other left xmr amounts and the price of the total xmr amount is averaged.Later that balance is used in the next arbitrage(if it will be profitable), also every 45seconds the xmr sell price is checked and if it is higher than our bought price the bot sell the left xmr amount.The same logic applies for ETH.

Exchange is only one - Poloniex .This bot is not doing arbitrage between exchanges.Its doing in-house arbitrage on Poloniex.Take a look at the logs.
