I've also tried arbitrage 3 days ago between poloniex and bittrex for emc2 coin. The gap was big enought to make profit. I transfer the tokens to bittrex. And then the gap got much smaller. So I finished it with a very little profit.
Nice sharing. Could you please share how you managed to spot the gap for that particular coin ? Are you continuously trading that coin alone or do you keep on checking multiple coins for gaps from one exchange to another exchange ? I just wonder how people finds the gap between exchanges and making profits from arbitrage trading.
I guess if we are holding some coins and checking for better prices in one or two exchanges then we may find gaps for that one particular coin. Otherwise we must need bots to help us to spot gaps across exchanges.
same would love to know how you detect those arbitrage.
