Hello ladies and gents!

Could anyone to help me and say: Are there arbitrage services which help to user automate trading between 2 or more exchanges from the single panel? Probably flow:
1. User register & login on the service website
2. See own wallet and replenishes it for 7000$
3. Go to the Monitoring panel and see the list of HOT arbitrage opportunities
4. Select the most profitable
5. Press button "buy BTC on exchange A" for 7000$.
6. After the completion of a transaction press button "sell BTC on exchange B" for 7200$
7. Gets 200$ of profit

Is there such service in the market right now? If no, what do you think about the reason?

Thanks in advance!
