I don't like talking $$$'s but points per day profit. You can then convert it to your bank into those dollars.

Im happy with a 1-2 unit profit a day. 1 point = bet size. So if you are betting $1000 then the profit would be $1-$2K. If you only bet $50 then your profit is $50 - $100.

I have lots of systems. I keep an eye on them but am always looking to add more.

I can do your arbitrage with a bot simply enough as I don't use commercial bot software. I write my own software but its hard to werite bots for people as websites change their layout a lot and scraping can be a pain when they do that. So I might write a bot that works for 2 months then breaks and I need to go see what happened to the site and fix the code. Of course if your sites use an xml feed or an api that makes it a lot better.
