How to make a profit doing 'spread trading'? I understand making a profit via arbitrage trading between multiple exchanges. I understand what spread is (gap between the bid &amp; ask). How can one make profits by leveraging this spread within a given exchange? Good examples will be helpful.
Thanks
If the spread is $40 you will buy $1 above ask price, then when fulfilled immediately resell the btc at $1 below bid price. You keep $38 profit per btc
