Yes, it's quite similar to Dinabot, I personally didn't like it / some features of it, so decided to make a better one (in my opinion

)
I have used Dinabot a lot of times in the past. The exchange fee rate is pretty high at Dinabot, otherwise it was pretty good and smooth. But your one is better as you are providing the service with 0.3% exchange fee only. You are providing a 3rd party service, but this type of service doesn't work automatically without API access from the site. Have you taken the API access from Eddie? Or will your exchange service work manually?
