You can but you need infrastructure to do so. I mean a human can not scout all available arbitrage opportunities presented before bots (Systems) spot and act on it thus erasing the opportunity for humans.
Even if one is able to spot the opportunity it should be acted on with lightning speed and definitely systems are much faster than individuals.
Even if managed to act it should be well executed. In this case I mean one should consider impact costs, slippages etc. Institutions are well equipped with execution type algos.
Also high volume and low profit margins work only if transaction costs are minimal and retailers are also cornered in this case.
Finally one should give credit to systems and should be ready to invest in infrastructure to work on high volumes with less profit margins successfully and consistently.
