I don't know if this thread is active or not but i would like to add my experience about arbitrage in general. Even though the concept of arbitrage is easy to understand you must gain experience in order to do it correctly. I am arbitraging markets for the last 7 years now and i have learned everything i know from a forum for free. Searching on google i came across a website named arbusers.com. It was(and still is) like a paradise of arbitrage talks and information. I learned everything i needed to know about arbitrage from there. Even if the site focus mostly on sport betting arbitrage, you can learn a ton of useful information about how arbitrage works, why it works and how the most successful do it. For the ones that interested to learn more you can try and check it.
