You aren’t going to make the most profit buying back in house. If you are that good at predicting line movement then you should just be betting one side. There are sites out there that show arbs every day using two books. Some sites call it sure bets. Even if you do it your way and wait for movement, having a provider with different lines will be best. Most people that arb are putting up more than $200.
If the OP is getting a ton of money down on the same bets then he is multi-accounting or working as a team. Once again it comes down to looking at bet slips from all involved.
I have no idea what's even happening in this thread now.
I do not use a bot, I am not arbing, my bets are just value bets on mostly esports.
I did not multi-account, I signed up to sportsbets.one which the same email I signed up to bitcointalk 7 years ago.
I also do not understand bot betting as you mentioned I do before, I still don't believe this is a real thing lol
