Always do your research on what you want to use and ask for proof that it works on an demo program that runs 24/7, if a product can't offer proof of their system working 24/7 all the time and making a profit, they are not worth even trying. I personally would suggest staying away from it if you are new to this, that is a very high end level of trading to use a bot to do arbitrage, there are a lot of ways to cover between being a newbie to doing that.
Totaly agree, that you should be fast.
And the second important things- it's excanage fees of crypto exchanges, if you have standart fees the arbitrage will give you only loses.
