India is a closed market which is controlled by many authorities. Forex market is also not open to everyone. This gives an opportunity to do do currency arbitrage.
There is a very good arbitrage opportunity between exchange platform ( bse and nse currency) and OTC market.
The opportunity is in pairs like Euro Inr, GBP Inr and Jpy Inr. The difference is around 15 to 20 paise in second month contract.
The average return on investment is more than 30% on an average basis. Please write to me on odilia.advisors@gmail.com for further details
