Because no one believes a random person can find arbitrage opportunities that hedge funds or high frequency traders are not already exploiting.. In this case I think most people are wrong. I think it is possible to still find arbitrage opportunities in the open market.
Oh, you can find opportunities. They just don’t have the RoI and scalability that hedge funds are looking for. Sometimes bigger scraps reach the ocean floor and it’s a big day in bottom feeder’s life to stumble upon one.
