had a lot of success in the past with Coinfalcon and Coss using another arbitrage tool that does not work anymore
would be interested to see theses 2 ones maybe

a great improvement of your tool could be a better maths with market depth and fees instead of basic calculator and "do it yourself"
often I see some really tiny ask or bid and this is shown as profit percentage . In fact 99% of the trade would occur at a lower one and benefit would be destroyed by fees and transfer.
As calculator use "1 BTC" as default value, it could lead to a lot of mistakes

But still a good tool
I renewed a few hours ago as promised
