From a couple of days i am seeing high prices on zebpay and low prices of koinex which provides an opportunity to make some money via arbitrage. I am going to share a couple tips if someone wants to make use of arbitrage opportunity.
1) Always ensure you have money in both the exchanges so in case you find some coin going down, you don't have to load money from your bank or do a NEFT on the spot.
2) find a considerable difference ( the difference should be good in amount like if ripple on koinex is 35 rs , it should be atleast 55 or 60 rupees in zebpay). This difference has to be seen because once you make a withdrawal from your koinex ripple address, it is going to take some time say 15 min to reach your zebpay. If the price difference is less like say 10 rupees , the window of arbitrage may go. Ensuring a healthy difference will give a better time window to do arbitrage.
3) Always pre-save your ripple, ethereum etc address in both the wallets so you don't waste time copying or doing a mistake transaction.
4) The arbitrage opportunity sometimes happen in odd hours so if you are online at 1am or 3am, you need to check out once a while where you might find yourself lucky.
5) Do not try to do arbitrage with bitcoin even if the difference is good because bitcoin transactions are costly, takes hell lot of time and if the arbitrage window closes you might lose your time and money on it.
The arbitage opportunity is not much seen among Indian exchanges. The price diff which you are suggesting is huge and I have never seen such a hue diff. in price among two Indian exchange. If in case such opportunity strikes, The transaction fees is quite high and after deducting transaction fees, taxes at time of buying/selling make the profit so less which is not even worth of making so many efforts.
