HI does anybody know of a good Arbitrage Trading Program trading BTC or USD?
The people who posted above have posted about a bot called GunBot. You can use that, because it is open source and the developer is active on social media channels and their forum. Quick support system and a growing community to help you when you need.
also is arbitrage profitable?
Depends on your opinion. Some people try out exchanges and use the minor differences in prices to buy on one exchange and sell on another taking advantage of the difference. That is one method to profit which the bot makes it easier since it observes several exchanges and runs the algorithm itself. You just have to put in your bitcoins there.
It does not mean you are guaranteed a profit. There may not be a positive difference every time. So use them at your own risk.
