The best currency ring to trade are those that has the most activity is the GBP/USD, USD/JPY and GBP/JPY. As you can see, all the 3 currencies present in this ring are the Big Movers of the market. It is advised that you trade only 1 currency ring per account as this will decrease undue drawdown that your balance can suffer with these type of strategies. It is also better in the sense that you will be able to study the behaviour of each ring separately and may better assess their performance. You should always start with very small lots initially... for example, if you have a 10,000usd account, you can start with 0.10 lots and then increase it as your balance increases. Compounding your earnings is among the best ways to increase your profits and grow your account. I hope that you benefit from all these. Take your time to study and practice the method on a demo account... A week or so is definitely not enough to get a good feel of the system, so be patient and enjoy it. Good luck
