the best part about arbitrage is u will never find difference in an online trading terminal.. We all will agree here that the online terminals are a bit slower in displaying rates in comparison to the other brokers with high frequency leased line.
Now you will never find that difference in the NSE BSE.. because there are traders with PRO account (Proprietor accounts, zero brokerage) to do it immediately. so if the gaps is there in the market it gets tapped immediately. so u will very rarely get that chance.. moreover there are illegal softwares too for NSE to BSE and viceversa arbitrage..
we do it normally with fast dealers but its getting tougher and tougher.
So better forget it like us in future..:thumb::thumb::clapping:
