It is possible but it is not easy at all, first of all forget about doing this manually, you will need a bot and you need it to be coded so it can run and execute your trades as fast as possible, you will also need the fastest server you can get as arbitrage opportunities can disappear in seconds and that can be the difference between making money or losing it, and if that was not enough you will need accounts on all exchanges and have capital there as well, so unless you can do all of that it should be better for you to forget about arbitrage.
