The recommended trade amount per arbitrage bot is between 0.1 and 0.2 BTC.

But if you go over to our wiki at https://wiki.haasonline.com/ then you will be able to find much more information about the arbitrage bots and there recommendations. For small questions i would recommend to send in an support ticket, send am PM or to create an topic on our forum. This way you get the answers as well and this topic will not turn into an slow chat.

No offence, but slow chats are just not really wanted in an more public topic like this, people who read things here just are looking for an good overview or the last news and things alike.  An slow chat does not contribute to it, instead because its specialized its just better to go in deep inside an topic on our own forum at https://forum.haasonline.com/. This advantage of this is that more people are looking into it and are likely to answer and respond.
