It's not worth it. Even if they don't ban you outright, the stakes/winnings are very limited for that kind of thing to make sense. And then there are odds data services like Betradar which provide every subscribing bookmaker with enough near-live data to instantly improve their prices so as to make any arbitrage very hard.

Gotcha. I figured it was too obvious of an idea for people to not already have optimized it.

Interesting about bookmakers being subscribed to a common line feed. I didn't know that, but it makes sense in a borderless-money, networked world.
