How much profit should you earn at least to cover this problem fiat -> bittrex -> binance -> bittrex -> fiat 
Cause if you cannot do this then arbitrage is meaningless. I realize 2% is just an example, however, I suppose you should have tried to trade like this on your own. Have you got any history?

There are more factors to take into consideration! However, for your question the most important are transaction fees. All related costs are included in the algorithm, so trades are just executed when the algorithm gives a positive signal. In this case it depends on the absolute value in order to cover the fees. The trades are also saved in the history, which is used for big data analytics in order to improve the algorithm. This can be checked in the Dashboard (start for history: 16/05/2018).
