You used to be able to do this, but it's not something which is present at the moment. Arbitrage has been taken over by bots, tons and tons of them who are verified on every site (both here and abroad) and who can capitalize on opportunities in milliseconds -- instead of people which is, of course, going to take a long time to figure out and is going to end up making you lose every single time against the bots.
So, it's not REALLY possible anymore.
telegram still provide some bots that display the differents price between market today. but maybe its only for a few famous coin like btc/eth and others.
this one can be used as the different between market but still, its highly risk at all.
