thanks for all the answers.
Arbitrage seems like the most straightforward type of trade to make. But apparently according to slippage and exchange rates and what not, I understand that it is actually not as easy to pull of in practice as in theory.
Anyone have experience?
well i am too lazy and too scared to do something like Arbitrage trading. but i have done some virtual-on-paper-calculations about it and most of the times it is not possible because of the fees and the spread.
on rare occasions when the difference is big the profit is possible but it is very small that is not worth the effort.
and on top of that (in my opinion) you have to trust two different exchanges with your money which is twice the risk
